Tips

Before installing, fully charge the new battery and then discharge it completely once or twice to calibrate the power gauge. Keep the battery contacts clean and avoid exposing the laptop to extreme heat, which can shorten battery lifespan. For best results, store the battery at around 50% charge if you won't be using it for an extended period.
