Battery 2-Power PW640 11.1v 6 cell 57Wh
The 2-Power PW640 11.1V 6-cell 57Wh laptop battery is a replacement pack designed to match the PW640 model. Built with high-grade lithium-ion/polymer cells, it delivers 57Wh (5200 mAh) capacity and reliable power for extended unplugged use. The pack is suitable for laptops that accept the PW640 battery form factor and provides a balance of run time and light weight (0.321 kg).
This 2-Power battery uses quality cells from recognized manufacturers to provide steady charging and discharge behavior, stable voltage output and consistent performance. The integrated SmartWatch Protect circuitry helps guard against short circuits and overheating during charging and discharging, improving safety and longevity compared with unprotected cells.
Shut down the laptop and remove the existing battery following the laptop manufacturer’s instructions. Insert the 2-Power PW640 battery into the battery bay, ensuring correct alignment and secure connection. Charge the battery fully before first use. Use the laptop’s original charger or a compatible charger specified by the laptop manufacturer. Monitor the device during charging and avoid exposing the battery to extreme temperatures.
Charge and discharge the battery within the laptop manufacturer’s recommended temperature range, avoid long-term storage at full charge, and replace the battery if you notice significant capacity loss, swelling, or abnormal heat during use.
