How to install BTI MC04-BTI 14.4V 40WHR Li-Ion Battery

• Prepare and safety check — Power off your laptop completely and disconnect any external power sources.

• Disconnect the old battery — Gently disconnect the battery connector from the system board. If your model uses a locking mechanism, release the latch or tab that secures the connector in place. Do not pull on the wires; instead, grasp the plastic connector or the battery housing itself for a safe removal.
• Remove and replace — Remove the old battery from its bay by sliding it out of the compartment. Take note of the orientation of the battery and connectors so the new pack can be installed in the same alignment. Align the MC04-BTI with the bay and slide it into place until you hear or feel a secure fit with the connectors aligned.
• Reconnect and test — Reconnect the battery cable to the system board, reseal the back panel, and tighten screws if necessary. Connect the charger and power on the notebook to confirm the battery takes a charge and reports status correctly. If the system shows a battery warning, re-check connections and restart to ensure proper recognition by the BIOS/firmware.
