Q: How do I change the internal battery?
A: The internal battery can be purchased from our store here. To replace the battery, remove the 2 screws from the base of the Square. This will allow you to carefully remove the face plate of the base exposing the internal battery and circuit board. The internal battery can be removed from place and detached from the circuit board. To detach from circuit board squeeze the white connector to release the battery. Connect new battery to circuit board and place battery back inside the Square housing. Reapply face plate and screw back into place.
