not to short-circuit the positive and negative terminals
5. Unsolder the terminals tips and clean the circuit board holes to prepare for the
installation of the new battery
6. Insert the new battery in the circuit board holes. Respect the battery polarity
7. Check that there are no short-circuits and resolder the battery terminals
