To reduce the risk of a short, you can use a battery isolation pick to disconnect the battery.

Be very careful when you isolate the battery using a battery blocker. The battery contacts are easily damaged, resulting in irreversible damage to the logic board.

Slide a battery isolation pick underneath the battery connector area of the logic board, and leave it in place while you work.

Alternatively, make a battery blocker using a playing card and slide it underneath the logic board connector to disconnect the battery.
