Tips

For best results, fully charge the battery before first use and calibrate it by running the laptop until it shuts down, then charging to 100% without interruption. Avoid exposing the battery to extreme heat or cold, and store it at around 50% charge if not used for extended periods. Always verify your original battery's voltage and connector type before ordering.
