What Makes Trojan 875 Golf Cart Batteries a Top Choice?
Trojan 875 golf cart batteries are flooded lead-acid batteries designed for deep-cycle performance, offering 170-190 Ah capacity and 6-8 year lifespans with proper care. Their rugged construction supports frequent discharging and recharging, making them ideal for golf carts, EVs, and renewable energy systems. Key features include high reserve capacity, low self-discharge rates, and compatibility with standard chargers.

How Do Trojan 875 Batteries Compare to Other Golf Cart Batteries?
Trojan 875 outperforms competitors like US Battery 2200 and Crown CR-235 in cycle life (1,200+ cycles at 50% depth of discharge) and amp-hour capacity. Unlike AGM or lithium alternatives, these flooded batteries require watering but deliver 10-15% more runtime per charge. Their 12.76V nominal voltage ensures compatibility with most 36V/48V golf cart systems.

| Brand/Model | Cycle Life | Capacity | Voltage |
|---|---|---|---|
| Trojan T-875 | 1,200+ cycles | 190Ah | 12V |
| US Battery 2200 | 900 cycles | 185Ah | 12V |
While lithium batteries offer 2,000+ cycles, their 3x higher upfront cost makes Trojan 875 more economical for moderate users. Flooded batteries maintain performance advantage in high-torque scenarios – Trojan’s 875 series provides 23% more cold-cranking amps than comparable AGM models. The calcium-alloy grid system reduces water consumption by 40% compared to traditional lead-antimony designs, striking a balance between maintenance and performance.
Why Proper Charging Crucial for Trojan 875 Longevity?
Overcharging reduces lifespan by 30-40%. Use smart chargers with:
• 3-stage charging (bulk/absorption/float)
• 14.4-14.8V absorption voltage
• 13.2V float voltage
• Temperature compensation
Charge after 50% discharge (every 15-20 miles in golf carts). Equalize monthly using 15.5V for 2-3 hours to prevent sulfation.

| Charging Stage | Voltage Range | Duration |
|---|---|---|
| Bulk | 14.4-14.8V | 4-6 hours |
| Absorption | 14.1-14.3V | 2-3 hours |
| Float | 13.2-13.4V | Indefinite |
Improper charging causes stratification – electrolyte separation that reduces capacity by 18% annually. Trojan’s research shows batteries charged within 24 hours of use last 27% longer than those left discharged. Temperature-compensated charging is critical, as every 15°F change requires 0.6V adjustment. For winter storage, maintain float charge at 13.02V to prevent freezing (electrolyte freezes at -92°F when fully charged vs. -17°F at 40% charge).

How to Maintain Trojan 875 Batteries for Optimal Performance?
Weekly maintenance checklist:
1. Check electrolyte levels (1/8″ above plates)
2. Clean terminals with baking soda solution
3. Tighten connections to 110-120 in-lbs torque
4. Test specific gravity (1.277 ± 0.007)
5. Inspect for case cracks
Use distilled water only. Never add acid. Store at 50-70°F with full charge.

“The T-875’s dual-purpose design bridges starting and deep-cycle needs better than any golf cart battery I’ve tested. Their unique paste formulation increases active material utilization to 87%, compared to industry-standard 78-82%.” – John Masterson, Golf Course Fleet Manager (22 years experience)
Conclusion
Trojan 875 batteries remain the gold standard for golf cart power, balancing cost ($180-$220 per battery) and performance. While requiring more maintenance than lithium alternatives, their 7-year ROI cycle and proven reliability make them ideal for moderate-use scenarios. Always purchase from authorized dealers to avoid counterfeit units (15% market infiltration reported in 2024).
