The 12-125-15-b from ForeverPure Power is a 24 Volt, 875 Ah tubular flooded lead-acid industrial traction (forklift) battery. Built with lead-antimony tubular positive plates, envelope separators, tank-formation curing, and Hardigg impact-resistant jars, this battery is engineered for deep-discharge duty cycles in 24/5 and 24/7 material-handling fleets. Each cell is rated for 1,500+ cycles at 80% depth of discharge and manufactured to Battery Council International (BCI) BCIS-14 capacity-test standards. Ideal for electric forklifts, pallet jacks, order pickers, sweepers, scrubbers, and other industrial material-handling equipment.
- Tubular positive plates with lead-antimony alloy for deep-cycle durability
- Envelope separators (polyethylene) prevent short circuits and improve acid circulation
- Tank formation curing for uniform cell capacity and longer cycle life
- Bottom bridge construction strengthens plate-to-strap connection and resists shedding
- Hardigg (or equivalent) jar with high impact resistance and chemical stability
- Flip vent caps with integrated electrolyte level indicator
- Single-point watering system compatible (Flow-Rite / Philadelphia Scientific)
- 1,500+ cycles at 80% DoD — exceeds BCI life-cycle minimum
- 7 positive plates / 8 negative plates per cell (15 total plates), 12 cells

Recommended charger voltage setpoints for a 24V system:
- Absorption: 28.2–29.4 V (constant voltage, stage 2)
- Float: 26.4–27.4 V (long-term maintenance, stage 3)
- Equalization: 30.0 V (2.50 V/cell, 2–4 hours, monthly or when cell SG spread ≥ 0.030)
- Discharge cutoff: 20.40 V (cutoff) per BCI
Watering:
- Use only distilled or deionized water — never tap water, well water, or acid
- Always water after a complete charge (prevents spill-over as electrolyte expands)
- Maintain level ≈ 0.25" below the bottom of the vent well, above the element protector
- Single-point watering system (Flow-Rite, Philadelphia Scientific) strongly recommended
Operating guidance:
- Do not discharge below 20% SoC (80% DoD) — SG 1.140–1.160
- Match charger to battery: voltage, Ah, and type — keep Ah variance < 10%
- Target duty cycle: 70% discharge, 6–8 h charge, 4 h cool-down before use
- If battery exceeds 115°F (46°C) during charge, inspect for damage or overcharge
- Check specific gravity of a pilot cell monthly with a temperature-compensated hydrometer
- Keep terminals clean, torqued, and protected with corrosion-inhibiting compound
- Inspect the battery for damage, leaks, or shipping-acid residue before installation.
- Verify tray/compartment fit against published dimensions: 13" W × 35" D × 30.5" H. Confirm counterweight requirement (battery weight: 1610 lbs) for the lift truck.
- Confirm correct voltage and polarity against the forklift nameplate.
- Use a rated battery-lifting beam with insulated hooks — never single-point or chain-sling.
- Clean terminals, apply anti-corrosion compound, and torque connector hardware to manufacturer spec.
- Ensure adequate ventilation — hydrogen gas becomes explosive at 4% concentration.
- Commission with an initial equalize charge; record baseline voltage, SG, and temperature for each cell.

ForeverPure Power flooded lead-acid batteries comply with OSHA 29 CFR 1910.1200 (HazCom 2012 / GHS), published per ANSI Z400.1 / Z129.1 and IMDG requirements.
- Primary hazards: Sulfuric acid (corrosive), lead compounds (IARC 2A carcinogen), hydrogen gas (flammable) generated during charging.
- PPE: Acid-resistant apron, face shield, chemical goggles, neoprene gloves, ventilated room.
- First aid: Flush skin/eyes with water for 15 minutes; seek medical attention immediately for acid contact.
- Spill response: Neutralize with sodium bicarbonate; dispose per local hazardous-waste regulation.
Available technical documents:
Lead-acid batteries are the most recycled consumer product in the United States, with a recycling rate above 99% (EPA, Battery Council International). The lead, polypropylene case, and sulfuric acid are all reclaimed at EPA-permitted secondary smelters and reused in new batteries.
- Federal law: Regulated under Universal Waste Rule (40 CFR Part 273) and RCRA hazardous-waste rules.
- State rules: Most US states require retailers and distributors to accept spent lead-acid batteries for recycling (the "Battery Act").
- Core charge: A refundable core charge may apply at purchase; returned cores are credited when received.
- Do not dispose in regular trash or with general recycling — this is prohibited in all 50 states.
- ForeverPure Corporation accepts spent FLA batteries for return and recycling. Contact us for a prepaid return label and core credit.

Q: What discharge rate is the 12-125-15-b rated at?
A: Industrial forklift batteries are rated at the 6-hour discharge rate: 875 Ah @ 6 hr per BCI BCIS-14. For renewable-energy / deep-cycle use the same cell delivers approximately 1400 Ah @ 20 hr.
Q: Is the 12-125-15-b a sealed (AGM/Gel) or flooded battery?
A: It is flooded (vented), tubular lead-acid. It requires periodic watering with distilled water and adequate room ventilation during charging. It is not sealed, AGM, or gel.
Q: How do I ship a wet/filled lead-acid battery?
A: It ships as UN 2794, Hazard Class 8 (Corrosive), NMFC 60680, Freight Class 70 via hazmat-certified LTL carrier, upright and non-stackable. We provide the shipping documentation; residential / lift-gate / inside delivery is quoted at checkout.
Q: How long will this battery last?
A: Under typical 24/5 forklift duty (one cycle per shift, 70–80% DoD), expect 5–7 years / 1,500+ cycles with proper charging, watering, and equalizing.
Q: What is the correct charger for the 12-125-15-b?
A: A 24V flooded-lead-acid charger matched to the battery's Ah capacity (within 10%), with 3-stage (bulk / absorption / float) profile and a monthly equalization setting at 30.0 V.
Q: Can I recycle the 12-125-15-b when it's end-of-life?
A: Yes. Lead-acid batteries are 99% recyclable. Return the spent battery to ForeverPure or any retailer accepting lead-acid cores for recycling. We issue a refundable core credit.
