Tips

For best results, fully charge the new battery before first use and calibrate it by running the laptop on battery until it reaches 5% once a month. Avoid exposing the battery to extreme heat or cold, and store it at 40-60% charge if you plan to keep it unused for several weeks. Always power down the laptop and disconnect the AC adapter before installation.
