Insert a Battery Blocker or other insulator underneath the logic board to separate it from the battery connector.

The battery blocker is an outdated way of isolating the battery, as you risk damaging the battery pins underneath the logic board. If you use this method, take extreme care to insert it gently and straight in the direction of the logic board. Don't significantly deform the the logic board as you do this. Don't twist or swing the pick side to side.

Leave it there to prevent the battery connector leads from making contact until you have completed your repairs.

The rest of the images in this guide show the logic board EMI shield reinstalled, which is incorrect. Follow the instructions, but keep the battery disconnected and do not reinstall the EMI shield until your repairs are complete.
