How to use

To install the battery, first ensure your laptop is completely powered off and disconnected from any external power adapter. Open the laptop chassis according to the manufacturer's service manual, carefully disconnect the old battery connector, and remove the unit. Insert the new MITSU battery into the designated compartment, secure it, and reconnect the power cable.
