Gas-powered EZ Go golf carts use a 12V automotive-style battery to power accessories and ignition. Regular maintenance includes checking terminals for corrosion, ensuring proper water levels (if non-sealed), testing voltage monthly, and storing the cart in moderate temperatures. Replace batteries every 3-5 years or when voltage drops below 12.4V.

What Type of Battery Does an EZ Go Gas Golf Cart Use?
EZ Go gas models typically use Group U1 12V lead-acid batteries with 35-50 Ah capacity. These feature top-post terminals and dimensions around 7.7″ x 5.1″ x 7.3″. Maintenance-free AGM (Absorbent Glass Mat) batteries are preferred for vibration resistance and leak-proof operation. Redway Power‘s RXU1-35 AGM battery is a popular aftermarket upgrade with 500+ CCA for reliable starts.
How Often Should You Replace a Gas Golf Cart Battery?
Replace gas golf cart batteries every 3-5 years. Signs of failure include slow cranking, dim lights, or voltage below 12.4V when fully charged. Test voltage monthly with a multimeter – healthy batteries show 12.6-12.8V at rest. Extreme temperatures and frequent short trips accelerate sulfation, the primary cause of lead-acid battery degradation.
Several factors influence replacement intervals. Carts used daily in hot climates may need battery replacement every 2-3 years due to accelerated electrolyte evaporation. Conversely, seasonal users in temperate zones might stretch service life to 6 years with proper maintenance. Conduct load tests annually using a carbon pile tester – batteries maintaining 9.6V under 50% load for 15 seconds remain serviceable. Always replace batteries showing physical damage like bulging cases or terminal deformation.
Can You Use a Car Battery in an EZ Go Gas Golf Cart?
Standard car batteries (Group 24/34) are physically too large but technically compatible. However, golf cart-specific batteries offer better vibration resistance and optimized cycling performance. Marine dual-purpose batteries like the Redway RX24M-DP provide 650 CCA and deep-cycle capabilities for accessory loads while fitting cart battery trays.
| Battery Type | CCA Rating | Cycle Life | Vibration Resistance |
|---|---|---|---|
| Standard Car | 600-700 | 150 cycles | Fair |
| Marine Dual-Purpose | 650-800 | 300 cycles | Excellent |
| Golf Cart AGM | 500-600 | 500 cycles | Superior |
Marine batteries bridge the gap between automotive and golf cart-specific models. Their thicker plates withstand deep discharges from accessories like stereos or LED light bars. When retrofitting larger batteries, ensure proper tray clearance and use polypropylene battery hold-down kits to prevent movement during operation.
Why Does My Gas Golf Cart Battery Keep Dying?
Common causes include parasitic draws (stuck solenoid, faulty voltage regulator), undercharging from infrequent use, or sulfated plates. Test for dark current by connecting a multimeter in series with the negative terminal – acceptable draw is <50mA. Use a maintainer like NOCO Genius2 during storage to prevent discharge below 12.4V.
How to Troubleshoot EZ Go Gas Cart Charging System Issues
Check alternator output (13.8-14.7V at 3,000 RPM), belt tension, and voltage regulator function. Test stator resistance (0.1-0.5Ω between yellow wires) and diode pack continuity. Weak charging accelerates battery sulfation. If output is low, inspect brushes and slip rings. Redway technicians recommend annual charging system inspections for carts over 5 years old.
“Gas golf cart batteries face unique challenges – vibration, temperature swings, and intermittent use. We recommend AGM batteries with reinforced plates and at least 18-month warranties. Always size the battery to match the cart’s electrical load – carts with light bars or stereos need 50Ah+ capacities. Proper maintenance doubles battery life in most cases.”

Conclusion
Optimizing EZ Go gas golf cart battery performance requires understanding its unique power demands and environmental stressors. Implementing regular voltage checks, using AGM technology, and addressing charging system issues promptly can extend service life beyond 5 years. For carts with added accessories, upgrading to high-capacity marine batteries ensures reliable operation.
FAQ
- How long to charge a gas golf cart battery?
- Charge until voltage reaches 14.4V (about 4-8 hours). Avoid overcharging sealed batteries – use smart chargers with automatic float maintenance.
- Can lithium batteries work in gas carts?
- Yes, but only use LiFePO4 batteries with built-in BMS. Redway’s RLFP12-40 offers 40Ah in same size as lead-acid, with 10-year lifespan. Requires voltage regulator modification for compatibility.
- Why battery dies after replacing alternator?
- Likely incorrect alternator voltage output or parasitic drain. Test alternator’s max output (should be 14.7V) and perform dark current test. New alternators sometimes have faulty diodes causing AC ripple.
