1. EV-Optimized Deep Cycle Performance

   Special active material resists capacity degradation under repeated stop-start discharge, supporting long daily operation of mobility and cleaning equipment.

2. Fully Sealed Non-Spillable Design

   Valve-regulated structure locks electrolyte inside, no acid leakage risk. No water refilling needed, safe for multi-angle installation inside equipment compartments.

3. Stable High-Load Discharge Output

   Consistent voltage output under climbing and heavy-load working conditions, effectively extending continuous running time per full charge.

4. Anti-Vibration Reinforced ABS Shell

   Thickened ribbed housing withstands bumps and vibration during movement, protecting internal plates and prolonging service life.

5. Low Self-Discharge Rate

   Slow self-discharge retains power during long idle storage, eliminating frequent supplementary charging.

Perfect power supply for electric wheelchairs, electric bikes & tricycles, low-speed electric vehicles, golf carts, sightseeing patrol vehicles, floor scrubbers and industrial electric sweepers.
