How to use

Power down the notebook and disconnect it from the mains before installing the replacement battery. Remove any service covers or screws required to access the battery bay according to the notebook manufacturer's instructions, then disconnect the old battery from the board and connect the replacement unit securely. Reassemble the device and charge the new battery fully before normal use. After installation, verify battery health and charge status within the operating system or using available diagnostics.

Recommendations

Store the battery charged to approximately 40–60% if it will not be used for prolonged periods. Avoid exposure to extreme temperatures and mechanical shocks. Use the notebook’s power management settings to optimize runtime and perform occasional full charge/discharge cycles as part of regular maintenance to help the battery management system report accurate capacity.
