Using an incompatible battery can lead to poor fit, charging issues, or device errors.
Power down the laptop and disconnect any external power source. Remove the existing battery following the laptop manufacturer’s instructions, then insert the replacement battery until it locks in place. Reconnect external power and charge the battery fully before first use. Verify battery recognition and charge level in the operating system or BIOS. Follow manufacturer guidelines for battery care and calibration.
For reliable performance, charge the battery fully before first use, avoid prolonged storage at full charge or deep discharge, and operate within recommended temperature ranges. Replace the battery if you observe significant capacity loss, swelling, or charging faults.
