Tips

To maximise battery lifespan, avoid extreme temperatures and perform a full discharge/recharge cycle once a month. Always ensure your laptop is powered off and unplugged before replacing the internal battery. For best results, calibrate the new battery by fully charging it to 100% and then letting it drain to 0% on first use.
