- Safety Pressure Release Valve
- Standard new safety technology for high-quality batteries.
- Prevents explosions caused by excessive internal pressures due to overcharging, short circuits, excessive temperature, battery deformation, or puncture.
- The safety valve on top is very important for the explosion-proof barrier. When the pressure inside the battery is built up, the safety valve opens to avoid an explosion.
- No Memory Effect
- Rechargeable batteries work under conditions that are often not fully discharged, and the capacity will quickly fall below the rated capacity. This phenomenon is called the memory effect. There are memories like nickel-metal hydride and nickel-cadmium batteries, but lithium-iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used with charging, no need to discharge and recharge.
