Tips

Before ordering, verify that your laptop's original battery has the same voltage (11.4 V) and a compatible connector. For best results, fully charge and discharge the new battery two to three times during initial use to calibrate the power gauge. Avoid exposing the battery to extreme heat or cold, and store it at around 50% charge if not used for extended periods.
