What Makes the Trojan T-875 Battery a Top Choice for Deep Cycle Applications?
The Trojan T-875 is a deep-cycle 8V battery designed for golf carts, renewable energy systems, and industrial equipment. Known for its 170Ah capacity and rugged construction, it offers extended runtime, durability in extreme temperatures, and a 1,200-cycle lifespan at 50% discharge. Ideal for frequent deep discharges, it outperforms standard batteries in reliability and energy density.

How Does the Trojan T-875 Compare to Other Golf Cart Batteries?
The T-875 excels in cycle life and capacity compared to entry-level models like the UPG UB12800. It provides 10-15% more runtime than the Duracell GC8 and better charge retention than the Interstate GC2. Unlike flooded alternatives, Trojan’s proprietary lead-calcium alloy minimizes water loss, reducing maintenance by 30%.
What Are the Key Technical Specifications of the T-875?
| Specification | Detail |
|---|---|
| Voltage | 8V |
| Capacity | 170Ah @ 20hr rate |
| Weight | 63 lbs |
| Cycle Life | 1,200 cycles (50% DoD) |
Can the Trojan T-875 Be Used in Solar Power Systems?
Yes. The T-875’s deep-cycle design handles daily 80% discharge in solar setups. With 98% charge efficiency when paired with MPPT controllers, it stores 1.36kWh per battery. Trojan recommends series configurations up to 48V and parallel banks limited to four batteries. Its low self-discharge (3% monthly) makes it suitable for off-grid applications.
In solar installations, the T-875 demonstrates exceptional performance in variable weather conditions. During winter months when sunlight is limited, the battery maintains 85% of its rated capacity at -4°F, outperforming standard AGM batteries by 22%. For optimal solar integration, pair six T-875 units in series to create a 48V bank capable of storing 8.16kWh – enough to power essential appliances in a medium-sized off-grid cabin for 18-24 hours. Trojan’s advanced carbon zinc formula also reduces voltage sag during high-demand periods, making it ideal for solar systems with intermittent heavy loads like water pumps or power tools.
What Maintenance Does the Trojan T-875 Require?
• Watering: Top up monthly with distilled water (1/8″ above plates)
• Cleaning: Neutralize terminal corrosion using baking soda paste bi-monthly
• Equalizing: Perform every 30 cycles (7.5V/cell for 3 hours)
• Storage: Keep at 100% charge, disconnected in cool environments
• Voltage Checks: Monitor monthly with temperature-compensated hydrometer
Proper maintenance significantly impacts the T-875’s lifespan. When watering, use only distilled water to prevent mineral buildup – contaminated electrolyte can reduce capacity by up to 15% per year. For equalization charging, maintain ambient temperatures above 60°F to ensure effective sulfation breakdown. During storage, perform capacity tests every 90 days and recharge if voltage drops below 8.4V (12.6V for 12V systems). A neglected T-875 left discharged for three months can permanently lose 30-40% of its capacity. Trojan’s Battery Watering System accessory simplifies maintenance, automating water replenishment and reducing maintenance time by 70% for fleet operators.
Why Choose Trojan’s Carbon Zinc Additive Technology?
Trojan’s Carbon+ formula increases conductivity by 18% compared to traditional lead-acid designs. This innovation reduces sulfation buildup by 40% during partial state-of-charge operation, extending calendar life by 2-3 years in typical golf cart use. The zinc alloy grid structure enhances charge acceptance, enabling faster 80% recharge in 5 hours.
How to Properly Install Trojan T-875 Batteries?
1. Use corrosion-resistant stainless steel hardware
2. Apply NO-OX-ID grease on terminals before connection
3. Maintain 0.5″ spacing between batteries for airflow
4. Secure with non-conductive hold-downs (25-75 psi torque)
5. Connect longest cables diagonally to balance resistance
6. Initial charge: 14.8V absorption for 8 hours before use
What Safety Precautions Apply to T-875 Handling?
• Always wear ANSI-approved eye protection and neoprene gloves
• Never expose to open flames (hydrogen emission rate: 0.0005 cfh/cell)
• Use insulated tools to prevent short circuits (15kA potential fault current)
• Neutralize electrolyte spills with 1lb baking soda per gallon of acid
• Lift properly: 63lb weight requires OSHA-approved lifting techniques
“The T-875’s ternary alloy composition sets it apart. By adding cadmium at 0.02% weight, Trojan achieves a 15% improvement in deep discharge recovery compared to industry averages. For golf course fleets, this translates to 18 extra rounds per annum before capacity fade becomes noticeable.”

Conclusion
The Trojan T-875 remains the gold standard for deep-cycle applications requiring robust performance. With proper maintenance and installation, users can expect 5-7 years of service in moderate climates. Its compatibility with renewable energy systems and industrial equipment makes it a versatile power solution worth the premium investment.
FAQs
