Which Golf Cart Battery Type Should You Buy?
Choose based on the cart's condition, how often you drive, the range you need, and how much routine maintenance you will do. Lithium is not automatically the best use of money for an older cart that also needs a controller, motor, brakes, or major wiring work.
| Buyer type | Best battery choice | Why |
|---|---|---|
| Daily neighborhood driver | Correctly sized lithium pack | Low routine maintenance; size capacity and BMS current for the route and cart |
| Budget replacement | Flooded lead-acid deep-cycle set | Lowest upfront cost and easy local availability |
| Low-maintenance lead-acid buyer | AGM deep-cycle batteries | Sealed design with less upkeep than flooded batteries |
| Older 36V cart | Matched 6V lead-acid set or full lithium conversion | Avoid mixing new and old batteries |
| Street-legal or lifted cart | Battery matched to controller and added load | Verify continuous and peak current instead of choosing by amp-hours alone |
| Seasonal owner | Either chemistry with a documented storage plan | Follow the maker's state-of-charge, disconnect, and temperature instructions |
If you are buying a used electric cart, battery condition should change the price. A cart that needs batteries soon can require another $900 to $4,000 after purchase. Use our used golf cart buying guide, golf cart value calculator, and used golf cart prices guide before you negotiate.
Best Golf Cart Battery Options to Shortlist
There is no single best golf cart battery for every cart. Voltage, tray size, controller draw, charger compatibility, and how far you drive all matter. Use this shortlist as a starting point:
| Category | Good fit for | What to look for |
|---|---|---|
| 48V/51.2V LiFePO4 pack | Daily neighborhood carts, lifted carts, street-legal carts | Capacity for the route, controller-compatible BMS current, charger, monitor, physical fit |
| Premium lithium brands | Owners keeping the cart long-term | Golf-cart-specific kits from established brands with strong warranty support |
| Value lithium packs | Budget lithium conversions | Verify BMS output, charger, cold-charge protection, monitor, and return policy |
| Flooded lead-acid set | Lowest-cost replacement | Matched 6V or 8V deep-cycle batteries from the same age and brand |
| AGM batteries | Owners who want sealed lead-acid | Proper deep-cycle rating, charger compatibility, and realistic range expectations |
Current golf-cart lithium options span value-focused complete kits and dealer-supported packages. Do not compare battery prices without checking whether the charger, monitor, mount, cables, accessory converter, and warranty support are included. For traditional lead-acid replacements, Trojan's T-875 remains a common 8V flooded deep-cycle reference point.
The important part is not the logo on the case. It is matching the battery to the cart's voltage, controller, charger, space, and expected range. If you are not comfortable checking those details yourself, use a local electric golf cart repair shop, compare ranked repair shops by state, or contact a dealer before ordering a lithium kit.

Types of Golf Cart Batteries
There are four main types of golf cart batteries. Each type performs differently and costs a different amount. Here's what you need to know to pick the right one.
Lead-Acid Flooded Batteries
Lead-acid flooded batteries are the most common and affordable option for golf carts. These traditional batteries contain liquid electrolyte (sulfuric acid and water) and require regular maintenance including water level checks and terminal cleaning.
Key Characteristics:
- Cost: About $150-$260 per battery, or $900-$1,600 for a six-battery set
- Lifespan: Commonly about 4-6 years with proper charging and maintenance
- Maintenance: High (monthly water checks, terminal cleaning)
- Weight: 60-80 lbs per battery
- Best for: Budget-conscious buyers, occasional use
AGM (Absorbed Glass Mat) Batteries
AGM batteries are a sealed lead-acid variant that eliminates the need for water maintenance. The electrolyte is absorbed in fiberglass mats, making them spill-proof and more resistant to vibration.
Key Characteristics:
- Cost: About $1,200-$2,100 for a full set
- Lifespan: Often about 5-7 years, depending on use, heat, and charging
- Maintenance: Low (no water required, occasional terminal cleaning)
- Weight: 55-75 lbs per battery
- Best for: Those wanting reduced maintenance without lithium cost
Gel Batteries
Gel batteries use a silica-based gel electrolyte instead of liquid, offering excellent deep-cycle performance and resistance to extreme temperatures. They're less common in golf carts due to higher cost and specific charging requirements.
Key Characteristics:
- Cost: Often $1,500-$2,400 for a full set
- Lifespan: Varies by product, charging profile, climate, and depth of discharge
- Maintenance: Low (sealed, no water required)
- Weight: 55-75 lbs per battery
- Best for: Extreme climates, deep-cycle applications
Lithium-Ion (LiFePO4) Batteries
Lithium iron phosphate (LiFePO4) batteries replace a multi-battery lead-acid set with one purpose-built pack or a matched drop-in kit. They remove watering and can reduce weight, but fitment and electrical compatibility matter.
Key Characteristics:
- Cost: $1,200-$3,500 DIY or $1,500-$4,000 installed
- Lifespan: Manufacturers commonly publish several thousand cycles; calendar life varies
- Maintenance: No watering; inspect the pack, cables, mount, and charger as directed
- Weight: Many 100Ah-class packs weigh about 50-110 lbs
- Best for: Frequent users who value lower weight and less routine maintenance
Battery Type Comparison at a Glance
*Lithium cycle ratings and charge times depend on the manufacturer's test conditions, usable capacity, charger output, temperature, and depth of discharge.
How Long Do Golf Cart Batteries Last?
How long your batteries last depends on the type, how you use them, how well you maintain them, and the weather. Here's what affects battery life and replacement costs.
Lifespan by Battery Type
Lead-Acid Flooded: About 4-6 years is a useful planning range, but heat, deep discharge, charging, watering, storage, and daily workload can shorten or extend service life.
AGM Batteries: About 5-7 years is a common estimate. AGM removes watering, but it still needs the correct charger and can be damaged by heat, overcharging, or long periods at a low state of charge.
Lithium-Ion: Current LiFePO4 makers commonly publish several thousand cycles, but the number only makes sense with its test conditions. LiTime publishes 4,000 cycles at 100% depth of discharge and 6,000 at 80%, while Vatrer lists 4,000+ cycles for its 48V 105Ah kit. Neither rating guarantees a fixed number of calendar years. Heat, storage, current draw, charging, and warranty terms still matter. To see how replacement cycles fit into overall cart longevity, check our guide on how long golf carts last.
Factors That Affect Battery Life
Charging Habits
Use the charger or charge profile approved for the pack. Do not let lead-acid batteries sit discharged, and follow the lithium maker's instructions for routine charging and storage state of charge.
Temperature
Heat accelerates battery aging, while cold can reduce available capacity and may block lithium charging. Follow the battery maker's charging, discharging, and storage temperature limits.
Maintenance
Flooded lead-acid batteries need water and terminal checks at the intervals in the manual. Lithium removes watering but still needs secure mounting, clean connections, and periodic inspection. For easier watering, see when a golf cart battery watering system is worth buying.
Usage Frequency
Frequent deep cycles add wear, but long periods sitting discharged can also damage a pack. Compare cycle depth and storage habits, not mileage alone.
Terrain
Hilly terrain and frequent acceleration increase current draw, accelerating wear. Carts used primarily on flat ground typically achieve longer battery life than those regularly climbing hills.
Load Weight
Heavier loads (multiple passengers, cargo) increase power consumption and battery stress. Consistently overloading your cart reduces battery lifespan. See our guide on how much a golf cart weighs for weight considerations.
Lithium vs Lead-Acid: Complete Comparison
Compare the complete replacement, not chemistry alone. Lead-acid is often cheaper upfront and easier to source locally. Lithium removes watering and can reduce weight, but it may require a charger, mounting hardware, accessory converter, or professional setup.
How to Compare Long-Term Battery Cost
| Cost factor | Flooded lead-acid | Lithium |
|---|---|---|
| Initial battery cost | $900-$1,600 for a typical six-battery set | $1,200-$3,500 for a DIY pack or kit |
| Extra parts | Core charges, cables, terminal hardware | Charger, mount, monitor, cables, or DC-to-DC converter if not included |
| Installation | Usually a direct same-voltage replacement | $200-$500 is a useful labor allowance for a normal conversion |
| Replacement timing | Often planned around 4-6 years, but condition decides | Maker cycle ratings vary; warranty and actual use decide |
| Routine care | Watering, charging, cleaning, and connection checks | No watering; inspect mounting, cables, BMS status, and charger |
A simple ownership comparison is more honest than a fixed ten-year promise. For example, one $1,200 lead-acid set plus one future replacement would total $2,400 before labor or price changes. A $1,660 lithium kit could cost less over the same period only if it fits without major extras and remains in service long enough. Use your local quotes, expected ownership period, warranty terms, and annual use.
Performance Differences
Beyond cost, lithium can offer practical performance advantages when the pack is correctly sized for the cart:
More consistent voltage: A correctly sized lithium pack generally holds voltage more consistently under load than an aging lead-acid pack. The BMS can shut the pack down near its limit, so do not plan around the final few percent of indicated charge.
Shorter charging with the right charger: Current 100Ah kits paired with 18A to 20A chargers advertise roughly five to six hours for a full charge. Actual time depends on usable capacity, starting state of charge, charger output, and temperature. See the golf cart battery charging time guide for the math.
Lower battery weight: Replacing a 330- to 480-pound lead-acid set with a roughly 50- to 110-pound lithium pack can remove well over 200 pounds, depending on the exact configurations. That changes how much weight the cart carries. For model-specific numbers, see our golf cart weight guide.
Range depends on usable energy: Do not assume a fixed percentage gain. Compare usable kilowatt-hours, controller draw, speed, terrain, tires, passengers, accessories, and the condition of the old pack.
When Lead-Acid Still Makes Sense
Despite lithium's advantages, lead-acid batteries remain the right choice in certain situations:
- Limited budget: You want the lowest upfront replacement cost
- Infrequent use: Less than once per week
- Short ownership: Planning to sell the cart within 2-3 years and wanting to check current resale with our golf cart value calculator
- Older carts: Carts with compatibility issues or limited remaining lifespan
Golf Cart Battery Replacement Costs
Golf cart battery replacement usually costs $900-$1,600 for a flooded lead-acid set, $1,200-$2,100 for AGM, or $1,200-$3,500 for a lithium DIY project. A lithium conversion with installation typically lands around $1,500-$4,000.
To see how battery costs fit into the bigger picture, try our free Cost of Ownership Calculator, which factors in battery replacements, charging costs, and maintenance over your full ownership period.
| Battery replacement | Typical 2026 cost | What changes the total |
|---|---|---|
| Six 6V flooded batteries for a 36V cart | $900-$1,600 | Brand, amp-hours, core exchange, cables, local labor |
| Six 8V flooded batteries for a 48V cart | $960-$1,600 | Brand, amp-hours, core exchange, cables, local labor |
| AGM set | $1,200-$2,100 | Battery count, voltage, capacity, charger compatibility |
| Lithium battery or complete DIY kit | $1,200-$3,500 | Capacity, charger, monitor, mount, cables, converter |
| Installed lithium conversion | $1,500-$4,000 | Cart-specific wiring, regenerative braking, accessories, labor |
Current U.S. listings show why a range is more useful than one average. As of July 18, 2026, one golf cart dealer lists a six-battery flooded set from $900 and a Trojan T-105 set at $1,200, while another lists an individual Trojan T-105 at $194.99 before any core charge. Local pickup, core exchange, shipping, and regional inventory can move the quote.
Lithium pricing now overlaps premium lead-acid. A LiTime 48V 100Ah complete kit lists around $1,275 and a Vatrer 48V 105Ah kit around $1,660. Dealer-oriented options cost more: an Eco Battery 51V 105Ah battery lists at $2,178 before cart-specific parts and labor, while an Allied RS 48V 105Ah package lists at $2,700. Sale prices change, so compare what is actually included.
Budget separately for corroded cables, damaged hold-downs, taxes, core charges without an exchange, and installation. On lithium, confirm the charger, state-of-charge display, mounting hardware, charge-port adapter, and DC-to-DC converter before comparing two advertised prices.

7 Signs Your Golf Cart Batteries Need Replacement
Recognizing the warning signs of failing batteries helps you plan for replacement before being stranded. Battery, cable, and charger problems are common reasons a golf cart will not start, so use our complete diagnostic guide before assuming the battery pack is the only cause.
Inspecting a used cart's batteries? Our Buyer's Toolkit ($19) includes a 25-point inspection checklist with battery-specific tests, plus pricing data to know if the asking price is fair.
Significantly Reduced Range
If your cart used to travel 25-30 miles per charge but now only manages 15-20 miles, battery capacity has degraded significantly. A 30%+ reduction in range typically indicates batteries nearing end of life.
Slow Acceleration & Hill Climbing
Struggling to accelerate or climb hills that were previously easy indicates reduced power output. Weak batteries can't deliver the high current needed for acceleration.
Extended Charging Times
If charging takes materially longer than it did with the same pack and charger, test both. Slow charging can indicate battery degradation, a weak cell, poor connections, or a charger problem.
Visible Physical Damage
Bulging or swollen battery cases, cracks, leaking acid, or heavy corrosion on terminals are clear signs of battery failure. These conditions can be dangerous and require immediate attention.
Low Voltage Readings
A fully charged 6-volt battery should read 6.3-6.4V, and an 8-volt battery should read 8.4-8.5V. Readings below 6.1V or 8.1V after full charge indicate significant capacity loss.
Sulfur or Rotten Egg Smell
A strong sulfur smell indicates overcharging or internal damage causing hydrogen sulfide gas release. This is both a battery failure sign and a safety concern requiring immediate attention.
Age Beyond Expected Lifespan
Age raises the chance of reduced capacity, but it is not a diagnosis by itself. Combine the date code with range, under-load voltage, charge behavior, physical condition, and the maker's service guidance.
Testing tip: Check pack voltage, individual battery voltage, and voltage under load. One weak battery can pull down a series pack, but open-circuit voltage alone does not measure remaining capacity. Ask a battery shop to load-test the set before ordering replacements.
If you need exact rested voltage targets for 6V, 8V, 12V, 36 volt, and 48V systems, use our dedicated golf cart battery voltage chart and test guide.
Recommended Testing Equipment
A good digital multimeter is essential for diagnosing battery issues. Here's what we recommend:
Golf Cart Battery Maintenance Guide
Good maintenance makes batteries last longer and work better. Different battery types need different care. If you are reviving batteries after winter storage, our spring golf cart maintenance checklist has a step-by-step battery revival process with voltage targets.
Lead-Acid Battery Maintenance
Monthly Maintenance Tasks
Check electrolyte at the interval and level shown in the battery manual. Use only distilled water. Many makers instruct owners to perform normal watering after charging, but follow the procedure for your exact battery.
Remove corrosion with a mixture of baking soda and water using a wire brush. Rinse with clean water, dry thoroughly, and apply terminal protectant spray or petroleum jelly.
Ensure all cable connections are tight and free of corrosion. Loose connections cause resistance, heat, and reduced performance. Tighten to specifications but don't over-torque.
Use an equalization charge only when the battery and charger manuals call for it. Do not apply a generic extended overcharge to AGM, gel, or lithium batteries.
Recommended Maintenance Products
To properly maintain your lead-acid batteries, you'll need a few essential tools. For a full rundown including hydrometers, torque wrenches, and brand-specific socket sizes, see our complete golf cart tool kit guide.
Lithium Battery Maintenance
Lithium batteries remove watering and corrosion-prone interconnects, but they are not inspection-free. Follow the pack manual and check these items:
- Keep clean: Occasionally wipe down the battery housing to prevent dirt buildup
- Check connections and mounting: Inspect at the interval in the manual and torque terminals to the maker's specification
- Monitor the BMS: Investigate recurring voltage, temperature, current, or cell-balance faults instead of repeatedly resetting the pack
- Follow storage limits: Use the maker's required state of charge, disconnect procedure, temperature range, and inspection interval
Charging Best Practices
The right charging procedure depends on battery chemistry and the exact pack:
- Use an approved charger or charge profile. Match chemistry, pack voltage, connector, polarity, and charging current.
- Do not let flooded lead-acid batteries sit discharged. Recharge and maintain them according to the cart and battery manuals.
- Follow the lithium maker's storage instructions. Do not copy one brand's state-of-charge target or cold-weather rule to another pack.
- Investigate abnormal charging. Repeated faults, overheating, swelling, odor, damaged cables, or a charger that will not stop require service.
- Confirm low-temperature rules. Many LiFePO4 packs block charging below a specified temperature; some use self-heating.
For help choosing a replacement charger, see our golf cart charger buyer's guide. You can also add solar panels to keep batteries topped off between drives and extend their lifespan. For more maintenance information, see our complete golf cart maintenance guide.
Understanding Golf Cart Voltage Systems
Golf carts use either 36-volt or 48-volt electrical systems, which affects battery selection, performance, and compatibility.
How to Identify Your System Voltage
The easiest way to determine your golf cart's voltage is to count the batteries and identify their individual voltage:
Golf Cart Voltage Calculator
Tip: Count the fill caps (water holes) on each battery: 3 caps = 6V, 4 caps = 8V, 6 caps = 12V
36V vs 48V Systems Compared
| Feature | 36-Volt System | 48-Volt System |
|---|---|---|
| Common lead-acid layout | 6× 6V batteries | 6× 8V, 8× 6V, or 4× 12V batteries |
| Lithium replacement | Purpose-built 36V pack or approved series kit | Purpose-built 48V/51.2V pack or approved series kit |
| Range | Depends on usable energy and the cart | Depends on usable energy and the cart |
| Hill performance | Depends on motor, controller, pack current, load, and gearing | Depends on motor, controller, pack current, load, and gearing |
| Buying rule | Match the existing system unless planning a full electrical upgrade | Match the existing system unless planning a full electrical upgrade |
Brand Compatibility Guide
The badge on the cart does not determine the battery by itself. Model family, year, drivetrain, pack layout, charger path, and prior conversions all matter.
| Model family | Common battery setups | What to verify before replacement |
|---|---|---|
| E-Z-GO TXT | Older 36V lead-acid, later 48V lead-acid, gas starter battery, or converted lithium | Model year, PDS/DCS/TXT48 system, battery count, charger plug, cable routing, and controller limits |
| E-Z-GO RXV | 48V lead-acid, factory ELiTE lithium, or converted lithium | Regenerative-braking compatibility, controller settings, charger path, BMS current, and physical fit |
| Club Car DS | 36V or 48V lead-acid, gas starter battery, or converted lithium | Year and serial prefix, pack layout, OBC status, round-plug charging path, tray dimensions, and cables |
| Club Car Precedent, Tempo, and Onward | Commonly 48V lead-acid, factory lithium, converted lithium, or gas | Exact model, ERIC/OBC charging, six-8V versus other pack layouts, factory-lithium status, and warranty requirements |
| Yamaha G-series, Drive/G29, and Drive2 | 36V or 48V lead-acid, converted or factory lithium, or gas starter battery | Model generation, gas/electric drivetrain, tray dimensions, charger plug, onboard charging, and battery chemistry |
Use the golf cart batteries finder when you are ready to compare battery types, fitment checks, tools, and buying paths. For model-specific parts beyond the battery system, open the linked brand page. If you are comparing modern system voltages before buying a cart, the 48V vs 72V golf cart guide explains the speed, range, and cost tradeoffs.
Upgrading to Lithium Batteries
Keep the cart at its existing voltage unless you are deliberately upgrading the controller, wiring, solenoid, charger, and possibly the motor. A normal lithium conversion still requires more than swapping battery cables.
What's Required for Lithium Conversion
| Conversion item | Typical cost | Check before buying |
|---|---|---|
| Battery or complete kit | $1,000-$2,700 | Voltage, capacity, BMS current, regenerative braking, physical fit |
| Charger, if not included | $150-$300 | Approved charge profile, voltage, current, connector, polarity |
| Mounting hardware and cables | $0-$200 | Tray condition, secure hold-down, terminal layout, cable condition |
| 48V-to-12V converter, if needed | $40-$100 | Lights, stereo, USB ports, and other 12V accessories |
| Professional labor | $200-$500 | Cart-specific wiring, controller setup, testing, warranty terms |
Conversion Considerations
Before converting, verify:
- Controller and BMS current: Verify continuous and peak current, not just voltage and amp-hours.
- Regenerative braking: Carts such as the EZGO RXV need a pack and controller setup approved for regenerative current.
- Charger and receptacle: Use the battery maker's approved charge profile and confirm connector and polarity.
- Mounting and physical fit: Measure the tray and use hardware that prevents pack movement or cable strain.
- Accessories: Power 12V accessories through a correctly sized DC-to-DC converter instead of tapping the pack incorrectly.
- Warranty: Check the cart and battery terms, registration deadline, charger requirements, and installation exclusions.

Recommended Golf Cart Chargers
A quality charger is essential for battery longevity. Choose based on your battery type and golf cart brand:
Lithium buying note: Current complete kits can start around $1,200, while dealer-supported packages and installed conversions can approach $4,000. Compare the full package and contact a local golf cart dealer or electric cart repair shop if you need fitment or installation help.
Frequently Asked Questions
What are the best golf cart batteries?
Flooded lead-acid batteries are usually the lowest-cost replacement for an older or occasionally used cart. For frequent use and less maintenance, compare a purpose-built 36V or 48V LiFePO4 pack. The right choice must match the cart voltage, controller current, charger, tray size, and range needs.
How long do golf cart batteries last?
Flooded lead-acid golf cart batteries commonly last about 4-6 years with proper charging and maintenance. Lithium manufacturers commonly publish several thousand charge cycles, but calendar life varies with depth of discharge, heat, storage, current draw, and warranty terms.
How much does it cost to replace golf cart batteries?
A full flooded lead-acid golf cart battery set typically costs about $900-$1,600 before installation. AGM sets often cost $1,200-$2,100. A lithium conversion typically costs $1,200-$3,500 as a DIY project or $1,500-$4,000 installed, depending on the battery, charger, mounting parts, wiring, and labor.
Are lithium golf cart batteries worth the cost?
Lithium can be worth the higher upfront cost when the cart is in good condition, gets regular use, and will stay in your ownership for several years. It removes watering, reduces battery weight, and can shorten charging time. Compare the complete installed cost and warranty instead of assuming lithium will always be cheaper over a fixed period.
How do I know if my golf cart batteries are bad?
Common warning signs include reduced range, weak acceleration, materially different charge time, excessive voltage sag under load, repeated charger or BMS faults, swelling, leaks, severe corrosion, heat, or unusual odor. Inspect the cables and charger and load-test the pack before deciding that every battery needs replacement.
Can I replace just one golf cart battery?
Test the full pack before replacing one battery. A single replacement may be reasonable when the remaining batteries are similar in age and tested capacity, but putting one new battery into an aged, weak series pack often creates imbalance. Never mix battery chemistries, voltages, or incompatible capacities. Replacing the full matched set is usually better when several batteries are worn.
How often should I charge my golf cart batteries?
Follow the battery and charger manuals for charging frequency, storage state of charge, and temperature limits. Lead-acid packs should not sit discharged, while lithium instructions vary by manufacturer. Always use a charger or charge profile approved for the battery chemistry and pack voltage.
What is the difference between 36-volt and 48-volt systems?
A 36-volt cart commonly uses six 6-volt batteries. A 48-volt cart may use six 8-volt, eight 6-volt, or four 12-volt batteries, or one purpose-built lithium pack. System voltage alone does not determine range or hill performance; battery capacity, controller, motor, tires, load, and terrain also matter.
Can I upgrade my golf cart from lead-acid to lithium batteries?
Yes, many golf carts can be converted from lead-acid to lithium. A conversion typically costs $1,200-$3,500 DIY or $1,500-$4,000 installed. Verify the cart voltage, controller current, regenerative braking, charger, mounting hardware, accessory converter, and physical fit before ordering.
Why is my golf cart battery not holding a charge?
Common causes include sulfation, a damaged cell, a charger fault, loose or corroded connections, low electrolyte in a flooded battery, parasitic electrical draw, or one weak battery pulling down a series pack. Check the charger and cables, then test pack voltage, individual batteries, and voltage under load.
How do I maintain lead-acid golf cart batteries?
Follow the battery manual for watering intervals and electrolyte level. Use only distilled water, keep terminals clean and correctly torqued, and do not let the pack sit discharged. Run an equalization charge only when the battery and charger manufacturers specify it.
Conclusion: Choosing the Right Golf Cart Batteries
Choose the replacement that fits the cart, the budget, and how long you expect to keep it. Flooded lead-acid remains practical when upfront cost matters most. Lithium is worth comparing when the cart is sound, gets regular use, and you value lower battery weight and no watering.
Key Takeaways:
- Budget about $900-$1,600 for a flooded lead-acid set before installation
- Budget about $1,200-$3,500 DIY or $1,500-$4,000 installed for lithium
- Compare the charger, mounting hardware, cables, monitor, converter, labor, and warranty in the total
- Treat lithium cycle ratings as manufacturer specifications, not guaranteed calendar life
- Load-test a weak lead-acid pack and inspect the charger and cables before ordering replacements
- Match the existing system voltage unless you are planning a broader electrical upgrade
