What Are The Specs Of T-1275 12V Flooded Battery?
The Trojan T-1275 12V flooded battery is a lead-acid deep-cycle battery designed for heavy-duty applications like golf carts, floor scrubbers, and UPS systems. Key specifications include a 12V nominal voltage, 150Ah capacity (20-hour rate), and dimensions averaging 264–330mm (L) x 181–182mm (W) x 275–276mm (H). Operating weights range 40–55kg, featuring flooded/wet cell construction requiring periodic water maintenance. With typical cycle life of 1,200 cycles at 50% depth-of-discharge, it utilizes thick lead plates for sustained high-current performance in traction applications.

What are the key electrical parameters of T-1275?
The T-1275 battery delivers 12V nominal voltage with 150Ah capacity at C/20 discharge rate (7.5A load for 20 hours). Its reserve capacity averages 270 minutes at 25A discharge. Peukert’s effect causes ~18% capacity reduction at high 150A discharge—practical runtime drops to ~45 minutes. Pro Tip: Always derate capacity by 15% when sizing for electric vehicle applications to account for real-world voltage sag.
How does T-1275 compare to similar deep-cycle batteries?
| Model | Capacity (Ah) | Cycle Life |
|---|---|---|
| T-1275 | 150 | 1,200 |
| T-105 | 225 | 1,500 |
| US-2200XC | 232 | 1,800 |
Compared to Trojan’s flagship T-105, the T-1275 trades 33% capacity for 15% lighter weight—ideal for weight-sensitive EVs. However, its 6V T-105 sibling becomes preferable for 36/48V systems through series configurations. For example, six T-105s create 36V/225Ah vs. three T-1275s making 36V/150Ah. Practically speaking, T-1275 suits applications prioritizing compact footprint over maximum runtime.
What maintenance does T-1275 require?
Flooded T-1275 batteries demand monthly electrolyte level checks using distilled water—never top with tap water due to mineral contamination. Equalize charge monthly at 15.5–16.2V (temperature-dependent) for 2–8 hours to prevent sulfation. Posts require anti-corrosion grease, especially in high-humidity environments. For instance, marina-based scrubbers using T-1275s show 40% faster terminal corrosion without proper maintenance. Pro Tip: Install thermal compensation chargers to automatically adjust voltage ±30mV/°C from 25°C base.

FAQs
Yes, but limit discharge depth to 30% for daily cycling—flooded lead-acid degrades faster than AGM/GEL in renewable energy applications. Use 15.5V absorption charging for optimal performance.
How to store T-1275 during off-season?
Fully charge first, disconnect terminals, and store at 10–15°C. Perform refresh charging every 3 months—neglect causes permanent sulfation reducing capacity by 5%/month.
