What Are Trojan 8V Golf Cart Batteries?
Trojan 8V golf cart batteries are specialized deep-cycle power units designed for sustained energy delivery in low-speed electric vehicles (LSVs). The Trojan T-875 model, a 8V/170Ah lead-acid battery, is engineered for golf carts, utility vehicles, and industrial equipment, offering robust discharge cycles and resistance to vibration. Its design prioritizes high current output and longevity, with applications extending to floor scrubbers, patrol vehicles, and material-handling systems.
What defines the Trojan T-875’s technical specifications?
The T-875 operates at 8V with 170Ah capacity, utilizing thick lead plates and advanced paste formulations for 600–800 cycles at 80% depth of discharge. Its dimensions (approx. 16.5cm x 16.5cm x 24cm) enable modular stacking in 48V/72V configurations. Pro Tip: Pair batteries with identical manufacturing dates to prevent voltage imbalance during series connections.
Deep-cycle architecture allows 20% deeper discharges compared to standard automotive batteries without sulfation damage. For example, six T-875 units in series create a 48V bank delivering 8.16kWh, sufficient for 18–25 holes per charge in standard golf carts. Regular equalization charging at 9.5–10V per cell (every 30 cycles) dissolves sulfate crystals, maintaining 85%+ capacity through 500 cycles.
How do Trojan 8V batteries compare to lithium alternatives?
| Parameter | T-875 Lead-Acid | LiFePO4 8V |
|---|---|---|
| Cycle Life | 600 cycles | 3,000+ cycles |
| Weight | 22–24 kg | 8–10 kg |
| Cost/kWh | $90–$110 | $300–$400 |
While lithium batteries offer 5x longer lifespan and 60% weight reduction, the T-875’s $799–$1,280 price range provides immediate cost advantage for fleet operators. Lead-acid remains preferred for cold climates (-20°C operation) where lithium suffers capacity loss. However, lithium’s 95% depth-of-discharge capability nearly doubles usable energy per cycle.

FAQs
A 48V system (6x T-875) provides 4–6 hours continuous operation on flat terrain. Steep hills reduce runtime by 40% due to increased 200A+ motor draws.
Can T-875 batteries be used in solar storage systems?
Yes, but deep-cycle optimization for solar requires derating capacity by 20%. For off-grid setups, lithium or specialized solar lead-acid batteries outperform in daily cycling.
