Step 3Attach the battery holder.

Attach the battery holder.
Flip the board over and find the three large metal tabs and the outline of the battery holder.

First you probably should apply a small amount of solder to the middle tab. I did not do this step, but my battery sometimes has trouble making contact with ground and I think doing this will solve the problem.

Once that is done, line up the battery holder so that it matches the outline and solder it so that it is lined-up to the two outside tabs and flush with the board.
