The Trojan T-890 8V Flooded Battery delivers 190Ah capacity with robust performance in industrial applications like forklifts and floor scrubbers. Built as a flooded lead-acid battery, it excels in deep-cycle operations, offering 1,200+ cycles at 50% depth-of-discharge (DoD). Its low internal resistance (<0.5mΩ) ensures high current delivery, while the electrolyte circulation system maintains temperature stability from -20°C to 50°C. Pro Tip: Monthly electrolyte checks prevent sulfation, extending lifespan beyond 5 years in optimal conditions.

What are the core features of the T-890 8V Flooded Battery?
The T-890 uses flooded lead-acid technology with 8V/190Ah capacity, optimized for 80–100A continuous discharge. Its thick plates (4.2mm) enable 12-hour runtime in Class III forklifts. Seismic-resistant grids reduce vibration damage, critical for construction equipment.

Beyond basic specs, the T-890 employs microporous separators preventing dendrite growth. During deep discharges, these maintain 1.8V/cell cutoff integrity. For example, in floor scrubbers, it supports 6-hour cleaning cycles with 30% reserve capacity. Pro Tip: Pair with 8V-compatible chargers (2.45V/cell absorption) to avoid undercharging.
How does its cycle life compare to AGM alternatives?
The T-890 achieves 1,200 cycles at 50% DoD vs. 800 cycles for equivalent AGM batteries. Flooded designs allow electrolyte replenishment, mitigating acid stratification—a key factor in longevity.

| Parameter | T-890 Flooded | AGM Equivalent |
|---|---|---|
| Cycle Life (50% DoD) | 1,200 | 800 |
| Peak Current | 450A | 380A |
| Maintenance Interval | 30 days | 90 days |
While AGM batteries are maintenance-free, their sealed design suffers from irreparable water loss. The T-900’s accessible cells enable electrolyte adjustments after heavy use—critical in food processing plants where equipment runs 24/7.

What maintenance ensures optimal performance?
Monthly checks of electrolyte levels (maintain ¼” above plates) and terminal cleaning are mandatory. Use a hydrometer monthly to verify specific gravity remains 1.265±0.005.
Three-step maintenance protocol: 1) Clean terminals with baking soda solution 2) Tighten connections to 8Nm torque 3) Equalize charge monthly at 2.5V/cell. Neglecting equalization causes capacity loss—a forklift battery dropped to 70% capacity after 6 months of skipped equalization cycles.

FAQs
Yes, but limit to 0.2C (38A). Faster rates above 0.3C risk warping plates.
Is ventilation required for installation?
Mandatory—charging releases hydrogen gas. Maintain 1m³ airflow per battery bank.
What’s the shelf life when unused?
6 months at 25°C with monthly topping charge. Use maintain mode (2.23V/cell) for longer storage.
