Product Features
- High energy density: Half the weight and 40-50% smaller volume compared to nickel cadmium/nickel hydrogen batteries of same capacity
- High voltage: Single cell operates at 3.7V (average), equivalent to three nickel cadmium/nickel hydrogen batteries in series
- Safety performance: Aluminum-plastic packaging shows internal quality hazards through deformation rather than explosion
- Long cycle life: Over 500 charge/discharge cycles under normal conditions
- Environmentally friendly: Contains no harmful metals like cadmium, lead, or mercury
- No memory effect: Maintains full capacity throughout charge cycles
- Fast charging: Fully charges in 1-2 hours using constant current/voltage charger
- Customizable: Wide range of models available with thickness from 0.8-10mm and capacity from 40mAh to 20Ah
