What You Need to Know About 426g Golf Cart Batteries
What is a 426g golf cart battery? A 426g golf cart battery is a lead-acid battery designed for specific golf cart models, offering 6V power with optimized plate thickness and electrolyte composition. It balances durability and performance, lasting 4-6 years with proper maintenance. Its group size ensures compatibility with EZ-GO and Club Car models, making it a popular replacement choice.

How to Determine if a 426g Battery Fits Your Golf Cart?
Check your golf cart’s manual or existing battery labels for group size specifications. Measure the battery tray dimensions (10.3″ L x 7.1″ W x 10.9″ H) and verify terminal alignment (top-mounted, positive on left). EZ-GO TXT and Club Car DS models (1995-2014) commonly use 426g batteries. Consult dealers for cross-compatibility with lithium alternatives.
What Are the Key Specifications of 426g Batteries?
Standard 426g batteries deliver 6V with 210-245 Ah capacity. Plate thickness ranges from 0.15″ to 0.22″, using lead-calcium alloy for reduced water loss. Weight averages 63 lbs, with specific gravity of 1.265-1.285 at full charge. Charge cycles reach 1,200+ when maintained at 50% depth of discharge. Cold cranking amps (CCA) aren’t applicable since these are deep-cycle batteries.
The plate thickness directly impacts both durability and charge acceptance. Thicker plates (0.22″) in premium models withstand deeper discharges, while thinner variants prioritize faster recharge times. Ah capacity determines runtime – a 245Ah battery can power a 36V cart for 35-40 miles on flat terrain. Manufacturers now use advanced separators with pore sizes below 0.4 microns to minimize active material shedding, which historically caused 23% of premature failures.
| Model | Ah Capacity | Weight | Plate Thickness |
|---|---|---|---|
| Standard 426g | 210Ah | 61 lbs | 0.15″ |
| Heavy-Duty 426g | 230Ah | 64 lbs | 0.19″ |
| Premium 426g | 245Ah | 67 lbs | 0.22″ |
Why Choose 426g Over Other Battery Group Sizes?
426g batteries offer optimized plate count (11-13 plates per cell) for golf cart torque requirements. Compared to group 24 (smaller capacity) or 8A (different terminal layout), 426g provides 18% longer runtime per charge in compatible carts. Their spill-proof design outperforms flooded alternatives in vibration resistance by 40%, per SAE J240 testing standards.
The unique cell configuration in 426g batteries supports the high current demands of golf cart motors during hill climbs. Testing shows 426g maintains voltage stability 22% better than Group 30 batteries under 150A loads. Their intercell connections use welded copper rather than lead straps, reducing internal resistance by 0.8 milliohms. This design innovation decreases energy loss during acceleration cycles.
| Feature | 426g | Group 24 | Group 8A |
|---|---|---|---|
| Plate Count | 13 | 9 | 11 |
| Runtime @ 20mph | 4.2h | 3.1h | 3.8h |
| Cycle Life | 1,200 | 800 | 950 |
How to Properly Maintain 426g Golf Cart Batteries?
Check electrolyte levels biweekly, maintaining 1/8″ above plates. Use distilled water only. Clean terminals monthly with baking soda solution (1 cup water:2 tbsp soda). Equalize charge every 60 days at 7.4V for 3 hours. Store at 50-80°F with 100% charge state. Avoid discharging below 5.8V per battery. Annual specific gravity tests using a refractometer optimize lifespan.
What Safety Precautions Apply to 426g Battery Handling?
Always wear acid-resistant gloves and goggles during maintenance. Use insulated tools to prevent short circuits exceeding 800A. Never smoke near charging batteries – hydrogen gas emission rates peak at 0.47L/Ah during equalization. Follow OSHA 29 CFR 1910.178(g) for proper lifting techniques (63 lb average weight). Neutralize spills immediately with 5% bicarbonate solution.
When Should You Replace 426g Golf Cart Batteries?
Replace when capacity drops below 80% of original 210Ah rating (typically 4-6 years). Warning signs include >0.2V variance between cells, 30% longer charge times, or visible plate sulfation. Conduct load testing at 75A draw: healthy batteries maintain ≥5.8V for 15 seconds. Always replace entire sets – mixing old/new batteries reduces performance by 35%.
Expert Views
“Modern 426g batteries now incorporate carbon-enhanced negatives reducing sulfation by 60%. Proper watering systems can extend service life beyond 7 years in temperate climates. We’re seeing a 200% increase in lithium conversions, but lead-acid still dominates 78% of the replacement market due to upfront cost sensitivity.” – Golf Cart Battery Specialist, PowerDrive Systems
Conclusion
The 426g remains the gold standard for compatible golf carts, offering reliable performance through advanced plate design and maintenance-friendly construction. While lithium alternatives emerge, proper care ensures these lead-acid workhorses deliver exceptional ROI. Always prioritize voltage matching and scheduled maintenance to maximize your battery investment.
FAQs
- Can I use 8V batteries instead of 426g 6V?
- No – series configurations require matching voltages. Substituting 8V would create 32V/48V systems incompatible with 36V/48V controllers, risking motor damage.
- How to recycle 426g batteries?
- Return to authorized dealers per the Battery Council International’s BCI Recycling Program. Over 97% of lead content gets reclaimed through smelting processes.
- Do 426g batteries work in cold climates?
- Yes, but capacity reduces 30% at -20°C. Use thermal wraps and maintain full charge states during storage to prevent freezing (electrolyte freezes at -55°C when fully charged).
