What Makes Trojan T-875 Golf Cart Batteries Reliable?
Trojan T-875 golf cart batteries are renowned for their deep-cycle design, high capacity (170Ah), and 6-volt configuration, making them ideal for extended golf cart use. They feature robust lead-acid construction, spill-proof durability, and a lifespan of 4–6 years with proper maintenance. These batteries excel in consistent power delivery, terrain adaptability, and cost-effective performance.

How Do Trojan T-875 Batteries Compare to Other Golf Cart Batteries?
Trojan T-875 batteries outperform competitors like US Battery and Crown due to their thicker lead plates, higher reserve capacity, and superior cycle life. They provide 1,200+ cycles at 50% depth of discharge (DoD), whereas generic brands often fail after 800 cycles. Their 6V design ensures stable voltage under heavy loads, unlike 8V/12V alternatives prone to voltage sag.
What Are the Key Specifications of Trojan T-875 Batteries?
The T-875 offers 6 volts, 170Ah capacity, 1,265 minutes of reserve capacity, and 1,250 CCA (cold-cranking amps). Dimensions are 10.3″ L × 7.1″ W × 10.9″ H, weighing 63 lbs. Its deep-cycle design supports 80% DoD without sulfation damage, and the proprietary SureGrid plate technology enhances charge acceptance by 15% compared to standard AGM batteries.
Why Is Proper Maintenance Critical for Trojan T-875 Lifespan?
Neglecting maintenance reduces T-875 lifespan by 40%. Monthly equalization charges prevent stratification, while distilled water refills maintain electrolyte levels. Terminals require lithium grease coating to resist corrosion. Avoid discharging below 20% SOC (state of charge) to minimize plate degradation. Trojan’s Hydrolink watering system can automate maintenance, cutting sulfation risks by 30%.
Consistent maintenance routines are vital for maximizing the Trojan T-875’s performance. For example, equalization charges should be performed every 30–60 days using a charger that delivers 7.55V per battery for 2–4 hours. This process reverses acid stratification, where concentrated sulfuric acid settles at the bottom of cells. A simple voltage check isn’t sufficient—use a hydrometer to measure electrolyte density across all cells. If specific gravity varies by more than 0.015 between cells, additional equalization is required. Below is a maintenance schedule for optimal performance:
| Task | Frequency | Tools Needed |
|---|---|---|
| Water refill | Every 15 charges | Distilled water, funnel |
| Terminal cleaning | Monthly | Baking soda, wire brush |
| Equalization | Every 45 days | Smart charger, hydrometer |
Can Trojan T-875 Batteries Be Used in Solar or Off-Grid Systems?
Yes, Trojan T-875 batteries are compatible with solar setups due to their deep-cycle endurance. When wired in series (48V system needs eight batteries), they provide 920Ah total capacity. However, their flooded design demands ventilation, unlike sealed lithium alternatives. For solar, Trojan recommends 14.8V absorption voltage and 13.2V float voltage to optimize charge cycles.
When integrating T-875 batteries into solar systems, consider their higher maintenance needs compared to lithium-ion alternatives. Flooded lead-acid batteries require regular water top-offs and ventilation to prevent hydrogen gas buildup. For off-grid setups, pair them with a charge controller that supports temperature compensation—this adjusts charging voltages based on ambient conditions. Below is a comparison of T-875 versus lithium batteries for solar applications:
| Feature | T-875 | Lithium |
|---|---|---|
| Cycle Life | 1,200 cycles | 3,000 cycles |
| Maintenance | High | None |
| Upfront Cost | $150/unit | $600/unit |
What Are Common Trojan T-875 Failure Signs and Troubleshooting Steps?
Key failure signs include voltage drops below 5.8V under load, swollen cases, and sulfated plates (white crust). Troubleshoot by checking specific gravity (1.277 ideal) with a refractometer. If cells vary by ±0.015, perform equalization. For terminal corrosion, clean with baking soda paste. Persistent low voltage often indicates a dead cell, requiring battery replacement.
How Does Temperature Affect Trojan T-875 Performance?
Trojan T-875 capacity drops 20% at 32°F and gains 12% at 100°F. In freezing conditions, charge voltage must increase by 0.003V/°F below 80°F to prevent undercharging. High heat accelerates water loss—check levels weekly in summer. Insulate battery compartments in winter to maintain optimal 77°F operating temperature, maximizing cycle life.
“Trojan T-875s dominate the golf cart market because they balance cost and performance. Their thick plates handle deep discharges better than 90% of AGMs. However, users must commit to watering schedules—I’ve seen T-875s last 8 years in fleets with automated maintenance systems.”

FAQ
- How often should I water Trojan T-875 batteries?
- Check water levels every 15–30 charging cycles. Refill with distilled water to 1/8″ below cell tubes. Never expose plates—overwatering causes acid dilution.
- Can I mix Trojan T-875 with older batteries?
- No. Mixing aged batteries reduces overall performance by 35% and risks overcharging newer units. Always replace all batteries in the pack simultaneously.
- What charger settings work best for Trojan T-875?
- Use a 6V smart charger with Trojan’s recommended profile: 7.35V absorption, 6.75V float, and 7.55V equalization. Avoid “universal” chargers—improper voltages cause premature aging.
