The Trojan T875 8V battery is a deep-cycle lead-acid battery primarily used in electric golf carts, floor scrubbers, and light-duty utility vehicles. With a 170Ah capacity and optimized plate design, it delivers sustained power for applications requiring frequent deep discharges. Its rugged construction withstands vibrations in municipal vehicles like patrol carts, while the 8V configuration enables flexible series wiring for 36V/48V systems common in recreational and industrial EVs.

What vehicles use Trojan T875 batteries?
The T875 powers golf carts, street sweepers, and airport tugs needing 36-48V systems. Three 8V units create 24V configurations for smaller EVs. Pro Tip: Always balance series-connected T875 batteries—voltage mismatches accelerate capacity loss.
Common applications include Club Car and E-Z-GO golf carts requiring 30–50 km range per charge. Municipal fleets deploy them in street cleaning machines due to vibration-resistant grids. For example, a 48V system with six T875s (8V×6) powers most mid-size scrubbers for 6–8 hours. Deep-cycle construction enables daily 80% depth-of-discharge without premature failure—unlike automotive starter batteries.
Why choose deep-cycle design?
T875’s thick lead plates and high-density paste withstand 600+ cycles at 50% DoD. Compared to automotive batteries:
| Feature | T875 | Car Battery |
|---|---|---|
| Plate Thickness | 2.8mm | 1.2mm |
| Cycle Life | 600+ | 30–50 |
Its tubular plate design reduces shedding during deep discharges. Maintenance demands include monthly water refills—sealed AGM variants exist but sacrifice 15% capacity. For cost-conscious fleets, the flooded T875 offers 3–5 years service if kept charged above 50%.

How does 8V optimize system design?
8V units simplify creating 48V EV systems (6×8V) versus 6V or 12V batteries. Fewer connections mean reduced failure points in commercial vehicles. Example: A 48V airport baggage tug needs 28 lead plates with 12V batteries vs. 18 plates using T875s—19% weight reduction. However, 8V configurations require precise charge balancing. Pro Tip: Use battery equalizers when stacking more than four T875s in series.
What maintenance ensures longevity?
Key practices include:
- Watering with distilled water weekly in summer
- Equalize charging monthly at 2.7V/cell
- Storing above 50% charge
Neglecting watering exposes lead plates, increasing internal resistance by 40% within 10 cycles. Use hydrometers to check specific gravity—1.277±0.007 when fully charged. For fleets, automated watering systems cut maintenance time by 75%.
Can T875 batteries handle fast charging?
Yes, but limit to 0.2C (34A for 170Ah). Faster rates risk plate warping. Charger specs should include:
| Parameter | Requirement |
|---|---|
| Absorption Voltage | 9.6–9.8V |
| Float Voltage | 9.0V |
Smart chargers with temperature compensation extend life by adjusting voltage ±0.03V/°C. Avoid charging below freezing—electrolyte stratification occurs, reducing capacity 30%.

FAQs
Not directly—lithium systems require different charging profiles. Use voltage converters if integrating with existing 48V LiFePO4 systems.
How to revive sulfated T875 batteries?
Apply controlled overcharge at 10.5V for 8 hours with electrolyte temps below 50°C. Success rates drop below 60% if voltage stays under 8V for over 30 days.
