What Are The Features Of T-875 8V Flooded Battery?
T-875 8V flooded batteries are deep-cycle lead-acid cells designed for sustained energy delivery in electric mobility applications. With a nominal 8V voltage and 170Ah capacity, they excel in golf carts, utility vehicles, and material handling systems. Their flooded design allows electrolyte maintenance for extended lifespan. These batteries prioritize high discharge rates (up to 5–6 hours) and durability, featuring robust plates and separators optimized for 800–1,200 cycles at 50% depth of discharge (DoD).

What voltage and capacity define the T-875?
The T-875 operates at 8V nominal voltage with a 170Ah capacity, delivering 1.36kWh per cell. This configuration balances power density and runtime—ideal for vehicles needing 6–8 hours of daily operation. Pro Tip: Always install T-875 batteries in matched series sets (6x8V=48V) to prevent voltage imbalance.
Beyond basic specs, the T-875’s 8V architecture reduces current draw compared to lower-voltage systems, minimizing heat buildup during deep discharges. Why does this matter? High-current paths in 6V systems accelerate cable degradation. For example, a 48V golf cart using six T-875 batteries sustains 25–30A at cruise versus 40–45A with 6V units. Always use corrosion-resistant lugs and torque terminals to 8–10 N·m for optimal conductivity.
How does flooded lead-acid chemistry impact performance?
T-875’s flooded lead-acid design uses liquid electrolytes for superior thermal stability and high surge currents. Unlike AGM or gel batteries, it tolerates overcharges better but requires monthly water top-ups. Pro Tip: Use only deionized water—tap minerals accelerate plate sulfation.
Practically speaking, flooded cells excel in high-vibration environments common in golf carts. The free electrolyte buffers plate stress, whereas AGM batteries might develop micro-shorts under similar conditions. However, their 70–75% charge efficiency (vs. 85–90% in lithium) means longer recharge times. A typical 48V T-875 pack needs 8–10 hours with a 15A charger. Did you know? Sulfation starts below 12.4V (6V cells)—invest in a quality maintainer for off-season storage.

Where are T-875 batteries commonly deployed?
T-875s dominate golf cart and industrial forklift markets due to their vibration resistance and deep discharge recovery. They’re also used in floor scrubbers and solar storage where cost/cycle matters more than weight.
Beyond mobility uses, their 170Ah capacity suits marine trolling motors requiring all-day runtime. For example, four T-875s in a 32V configuration power a 2,500W motor for 3–4 hours. But why not lithium? Initial cost—T-875 packs are 60% cheaper upfront, though lithium’s longevity offsets this long-term. Always secure batteries with 1/4″ stainless steel straps to prevent case cracks during off-road use.

What physical specifications affect installation?
Measuring 10.25″L x 7.12″W x 11.25″H and weighing 62 lbs, T-875s require reinforced battery trays. Their tapered terminals accommodate 5/16″ lugs—upgrade to marine-grade tinned copper for damp environments.
Space planning is critical—the standard 48V golf cart setup needs 30″x15″ footprint. Pro Tip: Allow 1″ clearance around each battery for cooling. Unlike compact lithium packs, flooded batteries vent hydrogen during charging. Install in well-ventilated compartments and check terminal torque quarterly (8–10 ft-lbs). Remember, improper clamping causes post fractures—use polypropylene hold-downs instead of metal.
How should T-875 batteries be charged?
Use 3-stage chargers (bulk/absorption/float) with 8V cell voltage limits. Bulk charge at 14.4–14.8V (2.4–2.47V/cell) until 80% capacity, then reduce to 13.8V (2.3V/cell) for absorption.
Why avoid cheap chargers? They skip absorption phases, causing stratification—acid layers form instead of mixing evenly. For optimal health, equalize monthly at 15V (2.5V/cell) for 2–3 hours. Example: A 48V T-875 pack needs 58–60V during bulk charging. Warning—overequalization corrodes plates; stop when specific gravity stabilizes at 1.277±0.007.
How does T-875 compare to similar models?
Unlike higher-capacity T-145 (260Ah) or lower-cost T-605, T-875 balances energy density and cycle life. Its 0.27C discharge rate suits moderate-load applications.
While lithium alternatives offer faster charging, T-875 remains king for budget-conscious fleet operators. A 6-bank T-875 setup delivers 48V/510Ah versus lithium’s 48V/200Ah at similar prices—but weigh 372 lbs versus 140 lbs. Consider load requirements—forklifts needing 3-hour shifts benefit more from T-875’s sustained output.

FAQs
Yes, but they require daily full recharge to prevent sulfation—pair with MPPT controllers maintaining absorption voltage for 4+ hours.
How often should water be added?
Check monthly—top up when plates are exposed, using distilled water to 1/8″ below fill wells. Never overfill—expansion during charging causes acid spillage.
