Good to know

Always verify that your laptop requires a 14.8 V, 4400 mAh battery with the same connector before ordering. The connector is device-specific and not included in this listing. For best results, fully charge and discharge the battery two to three times during initial use to calibrate the fuel gauge. Store in a cool, dry place when not in use.
