Forklift Lead-Acid Traction Batteries
Tubular-plate traction batteries for electric forklifts, pallet trucks, stackers and tow tractors. Multiple cell sizes support configurations matched to vehicle voltage, capacity and installation requirements.
Cell Engineering & Serviceability
Design details from the DAPAI traction battery catalogue, organized around performance, sealing and maintenance.
Positive Grid & Active Material
Quality alloy positive grids, improved active-material filling and optimized positive plate dimensions make effective use of the available cell space.
Tubular Cell Construction
Tubular positive plates are paired with flat negative plates and microporous separators. Impact-resistant polypropylene containers and heat-sealed lids form the cell enclosure.
Terminal Post Sealing
Alloy terminals incorporate internally threaded copper inserts. Compressed sealing rings around the posts help prevent electrolyte leakage.
Insulated Flexible Connectors
Insulated connector ends and a protected conductor form flexible inter-cell connections. Bolted fastening simplifies cell removal, maintenance and replacement.
Vent Plugs & Electrolyte Checks
Cell vent plugs allow charging gases to escape and provide access for water replenishment and electrolyte specific-gravity measurement.
Centralized Watering Option
Water can be supplied from a central point to the connected cells. Watering valves control the electrolyte level to simplify routine servicing.
Performance Characteristics
The catalogue includes reference curves for temperature versus capacity at the 5-hour rate, discharge voltage at different discharge rates at 30°C, depth of discharge versus cycle life, and charging voltage versus time.
Temperature & Capacity
Available capacity changes with battery temperature. Use the catalogue curve as a reference when assessing the operating environment.
Discharge Rate & Voltage
The discharge curves show how terminal voltage changes at different discharge rates and durations.
Depth of Discharge & Cycle Life
The reference curve illustrates the relationship between depth of discharge and cycle life; it is not a universal lifespan guarantee.
Reference curves apply to the conditions shown in the source. Final performance depends on the selected model, charging, maintenance and operating conditions.
