Here's a number that might surprise you: a well-maintained golf cart can last 20+ years. A neglected one? Often just 5-8 years before major failures start piling up.
The difference isn't luck. It's maintenance. And the good news is that most golf cart maintenance is straightforward, takes minimal time, and costs far less than the repairs you'll avoid.
This guide covers everything you need to know about maintaining both electric and gas golf carts. We'll show you exactly what to do, how often to do it, and why each task matters. Whether you're a new owner or just want to get more years out of your cart, you'll find actionable checklists and specific intervals—not vague advice like "check regularly."
Let's talk money. Maintenance isn't just about keeping your cart running—it's one of the best investments you can make as a golf cart owner.
The Bottom Line: Spending $1,500 on maintenance over 5 years preserves $2,200+ in resale value and avoids $1,500+ in emergency repairs. That's a 250%+ return on your maintenance investment.
Beyond the financial case, proper maintenance means:
Before diving into maintenance tasks, you need to know what type of cart you have. The maintenance requirements differ significantly.
How to identify your cart type:
For a deeper comparison, see our electric vs. gas golf cart guide.
Electric carts are generally lower maintenance than gas carts, but they have one critical component that demands attention: the batteries. Battery failure is the #1 reason electric golf carts end up in the shop—and proper maintenance can extend battery life by 2-3 years.
Task: Plug in your cart to charge after every use.
This is the single most important habit for electric cart owners. Here's why:
Smart Charger Safety: Modern smart chargers (also called "automatic" or "intelligent" chargers) monitor battery state and stop charging when full. You can safely leave your cart plugged in without overcharging concerns. However, older "dumb" chargers can overcharge—if yours doesn't shut off automatically, unplug when the charge cycle completes.
If you have flooded lead-acid batteries (the most common type), water level maintenance is critical. Skip this if you have lithium or AGM batteries.
Always check water levels AFTER a full charge cycle. Charging causes electrolyte expansion—adding water before charging can cause overflow and acid damage.
Pop off the caps on each battery cell. Most batteries have 3 or 6 caps per battery. Use a flashlight to see inside.
Water should cover the lead plates by 1/4" to 1/2". If you can see the tops of the plates, the water is too low. If water is at the bottom of the fill well, it's too high.
Use ONLY distilled water—never tap water. Tap water contains minerals that coat the plates and reduce battery capacity. Fill to 1/4" to 1/2" above the plates, not higher.
Press caps back into place firmly. Loose caps allow acid mist to escape, which corrodes nearby components.
Why Distilled Water Matters: Tap water contains calcium, magnesium, and other minerals. When water evaporates during charging, these minerals stay behind and coat the battery plates. Over time, this reduces the battery's ability to hold a charge. A gallon of distilled water costs $1-2 and protects batteries worth $800-$1,500+.
| Usage Level | Water Check Frequency | Why |
|---|---|---|
| Heavy (daily driving) | Weekly | High charging frequency = more evaporation |
| Moderate (2-3x/week) | Every 2 weeks | Standard evaporation rate |
| Light (weekly or less) | Monthly | Lower charging cycles |
| Hot climate (90°F+) | More frequent | Heat accelerates evaporation |
| Cold climate | Less frequent | Slower evaporation |
Corrosion on battery terminals is a silent performance killer. That white, crusty buildup you see? It's reducing power transfer and can eventually prevent your cart from running.
What you need:
Steps:
Proper tire pressure affects range, handling, and tire life. Electric carts are especially sensitive—low pressure increases rolling resistance and drains batteries faster.
Pro Tip: The exact PSI for your tires is printed on the sidewall. Check every 2-4 weeks—temperature changes affect pressure (expect to lose 1-2 PSI for every 10°F drop).
Brand-specific recommendations:
Go beyond water levels and do a comprehensive battery check:
Check brake function every 3-6 months:
Apply lubricant to moving parts:
Use white lithium grease or manufacturer-recommended lubricant.
Even if you handle all DIY maintenance, an annual professional inspection catches issues you might miss. A trained technician will:
Cost: $100-$300 for electric cart annual service
Battery maintenance differs dramatically based on battery type. Here's what you need to know:
Using the right charger is critical. A mismatched charger can undercharge (reducing capacity) or overcharge (damaging batteries permanently).
Charger matching rules:
For more on batteries, replacement costs, and when to upgrade, see our complete golf cart battery guide.
Gas carts require engine maintenance similar to a small automobile or lawn mower. The upside: no battery watering. The downside: more moving parts and fluids to manage.
Check fuel level — Running out of gas can damage the fuel pump and introduce air into fuel lines. Keep at least 1/4 tank.
Ensure the cart is on flat, level surface for accurate reading. Wait 5 minutes after running to let oil settle.
Find the dipstick (usually has a yellow or orange handle). Pull it out and wipe clean with a rag.
Reinsert dipstick fully, then remove and check oil level. Should be between MIN and MAX marks. Also check oil color—should be amber to light brown, not black or milky.
If low, add small amounts of 10W-30 oil (most common recommendation) and recheck. Don't overfill.
Oil condition warning signs:
The most important maintenance task for gas carts. Old oil loses lubrication properties and becomes acidic, damaging engine internals.
Change intervals:
What you need:
Note: Always check your owner's manual for model-specific requirements. Capacities vary by model year and engine type.
A clogged air filter restricts airflow, reducing power and fuel efficiency. Inspect every 3-4 months, replace annually or when visibly dirty.
Signs of a dirty air filter:
The fuel filter catches debris before it reaches the carburetor. Replace every 6-12 months depending on fuel quality and usage.
Check spark plug condition:
Replace spark plugs annually or when worn. Gap to manufacturer specification (typically 0.028-0.030").
A professional service for gas carts should include:
Cost: $150-$400 for gas cart annual service

Understanding maintenance costs helps you budget and make smart decisions about DIY vs. professional service.
Bottom line: $200-$400 in annual maintenance prevents $1,000-$3,000+ in repairs.
Learning from others' mistakes can save you hundreds or thousands of dollars.
The problem: Electrolyte expands during charging. Water added before charging overflows, taking battery acid with it and causing corrosion damage.
The fix: Always charge first, then add water. The only exception is if plates are exposed—add just enough to cover them, then charge, then top off.
The problem: Tap water contains minerals (calcium, magnesium, iron) that coat battery plates, reducing capacity by 20-30% over time.
The fix: Use only distilled water. It costs $1-2 per gallon at any grocery store. Your batteries cost $800-$1,500+.
The problem: Lead-acid batteries suffer permanent capacity loss when left discharged. Sulfation crystallizes on plates and can't be reversed.
The fix: Charge after every use. If storing, use a battery maintainer. Never let batteries sit more than 30 days without charging.
The problem: Unlike lead-acid, lithium batteries degrade faster when stored at 100% charge. High voltage causes accelerated cell aging.
The fix: Store lithium batteries at 50-70% charge. Check every 2-3 months and recharge to this range if needed.
The problem: Charging lithium-ion batteries below 32°F (0°C) causes lithium plating—permanent, irreversible damage that reduces capacity and can cause fires.
The fix: Never charge lithium batteries when they or the ambient temperature is below 32°F. Wait until they warm up naturally.
The problem: Leaving the cart in "Run" mode allows electronics to slowly drain batteries over storage periods.
The fix: Switch to "Tow" or "Storage" mode before any period of non-use longer than a week.
The problem: Low pressure increases rolling resistance (reducing range 10-15%), causes uneven wear, and can damage tires. Many owners never check pressure.
The fix: Check pressure every 2-4 weeks. Set a phone reminder if needed. Takes 2 minutes.
The problem: Old oil loses lubrication properties and becomes acidic. Engine wear accelerates dramatically, leading to early failure.
The fix: Change oil every 125 hours or 6 months, whichever comes first. Mark your calendar.
The problem: Mismatched voltage or chemistry damages batteries. A 48V charger on a 36V system, or a lead-acid charger on lithium batteries, causes permanent harm.
The fix: Match charger voltage exactly to your system. Use chemistry-specific chargers (lead-acid vs. lithium).
The problem: Reactive maintenance costs 3-5x more than preventive maintenance. Small issues become big repairs.
The fix: Follow a maintenance schedule. Simple prevention prevents 80% of common failures.

Golf carts should receive professional service annually or every 100-125 hours of operation. Between professional services, perform DIY maintenance on a schedule: daily charging (electric), weekly battery water checks during heavy use, monthly tire pressure and terminal cleaning, and quarterly brake inspections. Most owners spend 15-30 minutes per month on routine maintenance tasks.
Electric golf carts require battery-focused maintenance: charge after every use, check water levels weekly to monthly (lead-acid only), clean terminals monthly, and keep batteries fully charged during storage. Additionally, check tire pressure every 2-4 weeks, inspect brakes every 6 months, lubricate moving parts quarterly, and get annual professional service. Lithium batteries require less maintenance than lead-acid but have different charging rules.
Annual golf cart maintenance costs $200-$600 depending on whether you DIY or use professionals. DIY maintenance costs $50-$150/year (distilled water, cleaners, filters, oil). Professional service runs $100-$300 for electric carts and $150-$400 for gas carts annually. Major repairs if maintenance is neglected can cost $800-$2,000+ (battery replacement, carburetor rebuild), making preventive maintenance a smart investment.
Check battery water levels weekly during heavy use (daily driving) or monthly during moderate use. Add distilled water AFTER charging, not before, filling to 1/4" to 1/2" above the lead plates. Never use tap water as minerals damage batteries. In hot climates or during summer, check more frequently as heat accelerates water evaporation. Lithium batteries don't require water—this applies only to flooded lead-acid batteries.
With proper maintenance, golf carts last 15-20+ years compared to just 5-8 years without maintenance. Electric carts can last 20-40 years with diligent care. The key factors are battery maintenance (the most common failure point), regular service intervals, and protecting the cart from elements. A well-maintained cart also retains 70-80% of its value after 5 years versus 50-60% for neglected carts.
Most golf cart tires should be inflated to 18-22 PSI, with the specific recommendation printed on the tire sidewall. EZGO recommends 18-22 PSI front and 22-24 PSI rear. General guidelines: standard tires 20-22 PSI, low-profile tires 20-24 PSI, all-terrain tires 18-20 PSI (lower for more grip), and turf tires around 20 PSI. Check pressure every 2-4 weeks as temperature changes affect PSI.
Change gas golf cart oil every 125 hours of operation or every 6 months, whichever comes first. For brand-new carts, perform the first oil change after just 8-10 hours to remove manufacturing debris. Use 10W-30 oil as recommended by most manufacturers (EZGO, Club Car, Yamaha). Always drain oil while the engine is warm for complete drainage.
Yes, charge your electric golf cart after every use, even short trips. This practice prevents deep discharge cycles that damage lead-acid batteries and ensures your cart is always ready. Modern smart chargers prevent overcharging, so leaving the cart plugged in is safe. Exception: lithium batteries can be charged less frequently but should still be charged before dropping below 20% capacity.
Yes, most golf cart maintenance is DIY-friendly. Tasks like checking tire pressure, adding battery water, cleaning terminals, and checking fluid levels require no special skills. Intermediate tasks like changing oil (gas carts) or replacing filters need basic tools. Leave complex electrical work, brake system repairs, and controller diagnostics to professionals. DIY maintenance saves $150-$300 annually versus full professional service.
Warning signs include: reduced range or power (battery issues), slow acceleration, unusual noises (grinding, clicking, squealing), difficulty steering, spongy or weak brakes, visible corrosion on terminals, low or discolored oil, hard starting (gas carts), burning smell, and uneven tire wear. Address these promptly—small issues become expensive repairs if ignored.
Lithium batteries require different care than lead-acid: no water maintenance needed, store at 50-70% charge (not full), never charge below 32°F (0°C), and avoid complete discharge. Check BMS indicator lights monthly. Lithium batteries last 8-10+ years with proper care versus 4-6 years for lead-acid. They cost more upfront but require less maintenance and last longer.
Electric carts focus on battery maintenance (charging, watering, terminal cleaning) while gas carts focus on engine maintenance (oil changes, air filters, fuel system). Electric carts are generally lower maintenance with fewer moving parts. Gas carts require more frequent service intervals but don't have the battery replacement costs. Both need universal maintenance: tires, brakes, steering, and exterior care.
Inspect golf cart brakes every 6 months or immediately if you notice reduced stopping power, squealing, grinding, or the cart pulling to one side. Check brake pads for wear (replace when thin), inspect cables for fraying, test brake fluid level (if applicable), and verify the parking brake holds. Brakes are safety-critical—don't delay service if you notice any issues.
Yes, rarely-used carts still need maintenance. Lead-acid batteries self-discharge 5-15% monthly and can be damaged if left uncharged. Check and charge batteries every 30 days minimum, even if not using the cart. Run gas carts for 10-15 minutes monthly to circulate fluids. Check tire pressure before each use after extended sitting. A maintenance routine prevents the "hasn't been used in 6 months and now it won't start" problem.
For winter storage: fully charge lead-acid batteries (or 50-70% for lithium), use a battery maintainer, add fuel stabilizer to gas carts, inflate tires to maximum PSI, clean thoroughly, and use a quality cover. For year-round winter use: check tire pressure more often (cold drops PSI), keep batteries charged, consider an enclosure for weather protection, and never charge lithium batteries below 32°F. See our complete winterization guide for detailed steps.
