Tips

To maximize battery lifespan, avoid extreme temperatures and store the battery at around 50% charge if not used for extended periods. Calibrate your new battery by fully charging and discharging it a few times to ensure accurate power readings. Always use a compatible charger and disconnect the battery when the laptop is plugged in for long durations to reduce wear.
