Tips

To maximize battery lifespan, avoid exposing the notebook to extreme temperatures and store the battery at around 50% charge if not used for extended periods. Calibrate the new battery by fully charging and then discharging it once after installation. Always use a compatible charger and disconnect the power adapter once the battery reaches full charge to reduce stress on the cells.
