48V 550Ah Forklift Battery — Model 10VBS550

The 10VBS550 is a heavy-duty 48-volt 550Ah deep-cycle lead-acid battery engineered specifically for electric counterbalance forklifts, reach trucks, and electric pallet trucks operating in warehouses, distribution centers, and manufacturing facilities. With a nominal capacity of 550 ampere-hours at a 5-hour discharge rate, this battery delivers consistent power output across extended shifts, minimizing downtime for mid-shift battery swaps and maximizing warehouse productivity. Each cell uses high-density lead plate construction with advanced tubular positive plate technology that resists active material shedding, extending cycle life to 1,500+ charge/discharge cycles under proper maintenance conditions. The 10VBS550 is a direct OEM-compatible replacement for major forklift brands and meets or exceeds BCI (Battery Council International) Group specifications for industrial traction batteries.

Built with a rugged welded steel tray featuring corrosion-resistant epoxy coating and integrated lifting eyes, the 10VBS550 battery is easy to handle with overhead cranes or forklift battery extraction systems. The top-accessible cell connectors use lead-plated copper inter-cell links with torque-locked fasteners to ensure low-resistance electrical connections that won’t loosen under vibration. Each cell is equipped with flip-top vent caps for easy electrolyte level inspection and watering, and the battery includes a centralized single-point watering system option for automated maintenance. Key safety features include spark-arresting vent caps, flame-retardant cell covers, and insulated terminal posts rated for 350A continuous discharge with 500A peak surge capacity for heavy lifting operations.

This battery is compatible with a wide range of electric forklifts from Toyota, Hyster, Yale, Linde, Jungheinrich, Crown, Raymond, Clark, and Mitsubishi. It is ideal for Class I, II, and III electric forklift trucks requiring a 48V power source in the 500–600Ah capacity range. For optimal service life, maintain electrolyte levels 6mm above plate tops using only distilled or deionized water, perform equalization charges every 5–10 cycles, and keep battery tops clean and dry to prevent surface discharge paths.
