Tips

Before installing, fully discharge your old battery and power off the laptop. Use a plastic opening tool to avoid damaging the case. After installation, charge the new battery to 100% and then run it down to 10% once to calibrate the battery gauge. Store the battery at 40-60% charge if you won't use it for a long period.
