What Is The T-875 8V Flooded Battery Used For?
The Trojan T-875 8V flooded battery is a deep-cycle lead-acid battery designed for sustained power delivery in electric mobility applications. With an 8V nominal voltage and 170Ah capacity, it excels in golf carts, Golf Cart LiFePO4 Battery Category floor scrubbers, and low-speed electric vehicles requiring robust discharge cycles. Its flooded/wet-cell design balances cost and performance, supporting 450+ cycles at 50% depth of discharge (DoD). Typical configurations use six units in series for 48V systems in commercial fleets.
What distinguishes the T-875 from other 8V batteries?
The T-875’s deep-cycle design prioritizes longevity over cranking power, with thicker lead plates (+30% vs starter batteries) resisting sulfation. Unlike AGM or gel batteries, its flooded cells allow electrolyte maintenance, extending service life to 3–5 years with proper watering. Pro Tip: Use only distilled water to refill—tap water minerals accelerate plate corrosion.
For example, golf cart fleets using T-875s achieve 35–45 km per charge in hilly terrain. Battery OEMs like Trojan and US Battery optimize plate spacing for reduced internal resistance, enabling 20% faster recharge than generic alternatives. However, weight remains a tradeoff—each T-875 weighs 62 lbs (28 kg), requiring reinforced battery trays. A typical 6-battery pack totals 372 lbs, comparable to lithium alternatives but at half the upfront cost.
| Feature | T-875 | AGM Equivalent |
|---|---|---|
| Cycle Life (50% DoD) | 450+ | 300–400 |
| Maintenance | Monthly watering | Sealed |
| Cost per kWh | $90–110 | $130–150 |
Where is the T-875 battery most commonly deployed?
Over 75% of T-875 installations power golf course vehicles and resort shuttles. Its 8V architecture allows flexible series configurations—six units create 48V systems matching most golf cart drivetrains. Unlike lithium batteries, flooded lead-acid tolerates partial-state charging, making it suitable for fleet vehicles that sit idle for weeks.
Municipalities deploy T-875s in street sweepers and airport tugs requiring high torque at low speeds. Its surge current capability handles 300A momentary draws for incline starts. However, electrolyte stratification becomes an issue in flat-usage scenarios—proactive equalization charging every 30 cycles prevents capacity loss. Deep discharges below 20% SoC should be avoided; three consecutive full discharges can permanently reduce capacity by 15%.

FAQs
Check electrolyte levels monthly—plates should stay submerged by ¼”. Add distilled water after full charging to prevent overflow.
Can T-875s be used with lithium chargers?
No—lead-acid requires voltage-limited chargers (14.4–14.8V per 12V bank). Lithium profiles risk thermal damage from overvoltage.
