The T-1275 12V flooded battery is a lead-acid traction battery designed for deep-cycle applications. It features a nominal voltage of 12V, a standard capacity of 150Ah (with some models rated up to 155Ah), and dimensions averaging 330×182×275 mm. With a weight of ~55 kg, it’s optimized for electric vehicles, marine equipment, and industrial scrubbers. Its flooded-cell design requires periodic water refilling and offers 1,200+ cycles at 50% depth of discharge (DoD). Pro Tip: Pair it with a 12V smart charger maintaining 14.4–14.8V absorption voltage for optimal longevity.

What chemistry does the T-1275 use?
The T-1275 employs a flooded lead-acid (FLA) design with electrolyte suspension in liquid form. Its thick lead plates (6–7 mm) enhance durability for deep discharges. Unlike AGM or gel batteries, flooded cells require venting for hydrogen gas release and bi-annual electrolyte checks. For example, a golf cart using this battery would need monthly water top-ups in high-use conditions. Pro Tip: Always use distilled water—impurities accelerate plate sulfation.

What are the physical specifications?
Typical dimensions range from 264×181×276 mm to 330×182×275 mm, with a weight of 54–58 kg. Terminal posts are SAE-standard automotive posts (14.3 mm diameter). The case uses ABS plastic with 2V/cell internal partitions. Pro Tip: Measure your battery compartment before purchase—some EV models have tight clearances beyond nominal sizes.
| Dimension Type | Minimum (mm) | Maximum (mm) |
|---|---|---|
| Length | 264 | 330 |
| Width | 181 | 182 |
| Height | 276 | 275 |
What applications suit the T-1275?
Its traction design supports sustained power delivery for electric golf carts, floor scrubbers, and marine trolling motors. The high cyclic endurance (1,200+ cycles at 50% DoD) makes it ideal for daily-use equipment. For instance, a 6-battery 72V golf cart pack made with T-1275s provides 900Ah total capacity, enabling 60–80 km per charge in hilly terrain. Pro Tip: Avoid using it for short-runtime UPS systems—flooded batteries degrade faster with shallow discharges.

How does maintenance differ from sealed batteries?
Flooded batteries demand bi-annual electrolyte level checks and water refills to prevent plate exposure. Terminal cleaning every 3–6 months is critical to prevent corrosion-induced voltage drops. Comparatively, AGM batteries are maintenance-free but cost 40–60% more. For example, a marina using T-1275s in boat lifts would allocate monthly inspection schedules during peak season. Warning: Overfilling causes electrolyte spillage—maintain levels 3–5 mm above plates.
How does it compare to similar batteries?
| Feature | T-1275 (Flooded) | AGM Equivalent |
|---|---|---|
| Cycle Life (50% DoD) | 1,200 | 800 |
| Maintenance Frequency | Every 3–6 months | None |
| Cost (USD) | $1,200–1,750 | $1,800–2,400 |

FAQs
Yes, but only with modifications: AGM chargers lack sufficient voltage for flooded batteries, risking undercharging. Use a multi-stage charger supporting flooded chemistry.
What’s the max charge current for T-1275?
Limit to 30A (C/5 rate). Faster charging corrodes plates—thermal runaway occurs above 50°C case temperature.
