What Are 8V Trojan Golf Cart Batteries?
8V Trojan golf cart batteries are deep-cycle lead-acid units designed for sustained power delivery in electric vehicles like golf carts and patrol vehicles. Models like the T-875 and S-875 offer 170Ah capacity, optimized for repetitive discharging and recharging cycles. Their rugged construction ensures reliability in demanding applications, while the 8V configuration allows flexible series connections for 48V or 72V systems common in mobility solutions.
What defines an 8V Trojan golf cart battery?
These batteries use flooded lead-acid technology with thick plates for deep discharges. Rated at 8V nominal voltage, they’re engineered for 1,000+ cycles at 50% depth of discharge. Pro Tip: Always maintain electrolyte levels above plate tops to prevent sulfation damage.
Trojan’s 8V series employs a tubular positive plate design enhancing surface area for improved energy density. For example, the T-875 delivers 170Ah over 20 hours, enabling 45–60 km range per charge in standard golf carts. Practically speaking, these batteries thrive in applications requiring daily deep cycling—unlike starter batteries that prioritize short bursts. But how do they handle heat? Internal separators with microporous structure mitigate acid stratification in high-temperature environments.
| Model | Capacity (Ah) | Primary Application |
|---|---|---|
| T-875 | 170 | Golf carts, utility vehicles |
| S-875 | 160 | Marine, low-speed EVs |
How are these batteries maintained?
Proper maintenance requires monthly equalization charges to balance cell voltages. Use distilled water to refill cells after charging, never before. Warning: Overwatering dilutes electrolyte, reducing performance.
Deep-cycle batteries demand specific charging protocols—a three-stage charger with 2.45V per cell absorption voltage ensures full reconditioning. Transitioning from bulk to float mode prevents overcharging. For instance, a 48V system (six 8V batteries) needs 58.8V absorption voltage. Pro Tip: Install temperature-compensated chargers to adjust voltage based on ambient conditions. Why does this matter? Lead-acid efficiency drops 0.3% per °C above 25°C, risking thermal runaway without compensation.

FAQs
Yes, but avoid partial state-of-charge operation—maintain above 50% SOC daily to prevent premature capacity loss.
How long do these batteries typically last?
3–5 years with proper maintenance; neglect reduces lifespan to 12–18 months due to sulfation.
Are vent caps necessary during operation?
Critical—always keep caps sealed to prevent electrolyte spillage but open during watering to release hydrogen gas.
