Battery

Install the battery as shown. Do not actually plug the battery into the board at this time.

Put one of the double sided tape circles on the battery where shown. You can add additional double sided tape of your own if you like, but this small dot is enough to keep the battery in place. If you ever need to remove the battery, having too much tape may make it difficult as the battery is installed in tight area.

Clear the wires out from between the upper and lower frame plates to prepare a space for the battery. You may also wish to wipe the lower frame with rubbing alcohol to clean the surface for better tape adhesion.

Install the battery as shown. Make sure the wires are coming out toward the rear of the battery.

Route the battery cable up to the main board as shown. DO NOT PLUG IN THE BATTERY AT THIS TIME.
