What Is The T875 Trojan 8V Golf Cart Battery?
The Trojan T-875 is an 8-volt deep-cycle lead-acid battery designed for electric golf carts and utility vehicles. With a 170Ah capacity and thick plate construction, it delivers sustained power for multi-passenger EVs like tourism carts and floor scrubbers. These batteries excel in series configurations (typically 6x8V=48V systems) and prioritize durability in deep discharge-recharge cycles. Proper maintenance ensures 4-6 years of service life in moderate climates.
Understanding the Lifespan of Trojan Golf Cart Batteries
What are the technical specifications of the T-875 battery?
The T-875 operates at 8V nominal voltage with 170Ah capacity at 20-hour rate. Its thick lead plates withstand 1,200+ cycles at 50% depth of discharge (DoD). Measuring ~10.3″ L x 7.1″ W x 10.9″ H, it weighs ~63 lbs. Designed for deep-cycle performance, it tolerates 80% DoD better than starter batteries. Pro Tip: Use hydrometer readings monthly—specific gravity below 1.225 signals needed equalization charging.
Trojan’s exclusive XC2® alloy grids reduce corrosion, extending life in frequent partial-state-of-charge scenarios. For example, six T-875s in a 48V golf cart system deliver ~10.2kWh capacity, enabling ~25 miles per charge with 800W loads. But why do terminal designs matter? The dual-post terminals (SAE and 5/16″ stud) prevent connection errors during series wiring. Always torque terminals to 95-105 in-lb using corrosion-resistant washers.
Where is the T-875 battery commonly deployed?
This battery dominates electric golf cart markets, especially older 36V/48V Club Car and EZGO models. Beyond fairways, it powers floor scrubbers (4-6 batteries), neighborhood EVs, and renewable energy carts. Municipalities use them in airport tugs requiring 500+ daily cycles. Pro Tip: Pair with on-board chargers using temperature compensation (-3mV/°C/cell) to prevent winter undercharging.
In tourist parks, four T-875s create a 32V system for 8-seater carts hauling 1,500 lbs. up 15% grades. But how does it handle vibration? The polypropylene case withstands 5G shock—critical for off-road patrol vehicles traversing potholes. Redway engineers recommend adding adhesive battery mats in extreme conditions to minimize case abrasion.

| Application | System Voltage | Typical Runtime |
|---|---|---|
| Golf Cart | 48V (6x8V) | 4-6 hours |
| Floor Scrubber | 24V (3x8V) | 3-5 hours |
How does the T-875 compare to similar models?
Unlike the 6V T-105 (225Ah) for heavy loads, the 8V T-875 offers voltage flexibility in compact EVs. The 12V T-1275 trades cycle life (900 cycles) for higher per-battery voltage. Pro Tip: Mixing voltages in series-parallel arrays destroys batteries—stick to identical units.
| Model | Voltage | Ah Capacity |
|---|---|---|
| T-875 | 8V | 170 |
| T-105 | 6V | 225 |

FAQs
Yes—electrolyte freezes at -58°F when fully charged but at 18°F when discharged. Keep SOC above 75% in sub-freezing temps using float chargers.
How often to water T-875 cells?
Check monthly, adding distilled water after charging. Never expose plates—maintain 1/8″ below fill wells.
What charger voltage suits 48V T-875 systems?
57.3-58.5V absorption (2.4-2.45V/cell), tapering to 54.4V float. Exceeding 59V accelerates grid corrosion.
