Tips

To maximise battery lifespan, avoid exposing the laptop to extreme heat and perform a full charge-discharge cycle once a month. Calibrate the new battery by charging it to 100% and then letting it drain completely before recharging. Store the battery at around 50% charge if it will be unused for extended periods.
