The Trojan T-1275 is a deep-cycle lead-acid battery specifically engineered for golf carts and utility vehicles, featuring a 12V configuration and 150Ah capacity. Designed for sustained power delivery and cyclic endurance, it employs valve-regulated (VRLA) technology for maintenance-free operation. With a typical lifespan of 5–7 years under proper maintenance, its 39–55 kg weight balances energy density and structural durability. Charging requires 14.4–14.8V absorption voltage with float stages to prevent sulfation.
What are the technical specifications of the T-1275 battery?
The Trojan T-1275 operates at 12V nominal voltage with 150Ah capacity, using thick lead plates for deep discharges. Dimensions vary between 32×18×28 cm and 26×18×27 cm across models. Pro Tip: Always verify terminal type (F2 vs. L-connectors) to match your cart’s wiring. For example, its 750 CCA (cold cranking amps) supports 1–2 hours of continuous golf cart operation on hilly terrain.
Where is the T-1275 battery commonly used?
Primarily deployed in electric golf carts, the T-1275 also powers marine equipment, floor scrubbers, and solar storage systems. Its vibration-resistant case suits off-road EVs, while the 12V architecture allows easy voltage stacking. Pro Tip: Pair six T-1275 units in series for 72V systems in heavy-duty carts—ensure uniform charge cycles across all cells.

How does the T-1275 compare to other Trojan batteries?
| Model | Voltage | Capacity | Lifespan |
|---|---|---|---|
| T-1275 | 12V | 150Ah | 5–7 years |
| T-105 | 6V | 225Ah | 4–6 years |
The T-1275’s higher voltage reduces wiring complexity compared to 6V T-105 arrays, but trades off total energy (1.8kWh vs. 1.35kWh). Its modular design suits space-constrained installations.
What maintenance does the T-1275 require?
As a VRLA battery, it eliminates water topping but needs bi-monthly terminal cleaning to prevent corrosion. Use dielectric grease on posts and verify specific gravity quarterly (1.277 ±0.007). Pro Tip: Equalize charge every 30 cycles using 15.5–16.1V for 2–4 hours to balance cell voltages.

How should the T-1275 be charged?
Optimal charging uses three-stage smart chargers delivering bulk (14.4–14.8V), absorption (14.1V), and float (13.2V). Charge immediately post-discharge—delays beyond 24 hours risk permanent sulfation. For instance, a 25A charger refills 150Ah in 6–7 hours, while 10A models take 15 hours.

FAQs
Yes, series configurations up to 48V are safe with matched batteries. Always use identical age/capacity units and monitor individual voltages during charging.
What’s the T-1275’s shelf life when unused?
Store at 13.2V in cool environments—discharged units degrade within 3 months. Recharge every 6 weeks if idle.
