The following six steps show how to remove the battery from a 41 mm Apple Watch Series 7.

Insert an opening pick between watch body and the long edge of the battery.

Use constant, steady pressure to slowly pry up the battery.

Take care not to puncture or bend the battery with your tool—a punctured or bent battery may leak dangerous chemicals or cause a fire.

Don't try to remove the battery all the way yet. It is still connected to the motherboard.
