Installation guide - Replacing a laptop battery
General guidance for this part type - always follow your device manual- Screwdrivers for your bottom cover (Phillips or Torx)
- Plastic opening pick
- Isopropyl alcohol for glued batteries
- Match the model code and voltage printed on the old battery's label to this listing.
- If the old battery is swollen, do not press, bend or puncture it. Tape over its contacts and take it to a battery recycling point; never put it in household trash.
- 1Check your battery type. If the battery slides out from the outside, push its latches and swap it without opening anything. Otherwise continue below.
- 2Prepare and open. Shut the laptop down fully (not sleep) and unplug the charger. Remove every screw from the bottom cover, including any under rubber feet or labels, then release the clips with a plastic pick starting at a corner near the hinge.
- 3Disconnect the battery first. Unplug the battery connector from the board by pulling the plug body straight out, parallel to the board, never by its wires.
- 4Remove the old battery. Undo the screws that hold it. Some thin laptops glue the cells in place; soften the glue with isopropyl alcohol and lift with a plastic card. Never pry or bend the cells.
- 5Fit and test. Screw the new battery in, connect it, refit the cover and power on with the charger attached. Check that the system reports the battery and charge it to 100% before unplugged use.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
