How to Rebuild a Motorola GP300 Battery

Updated April 17, 2017

The Motorola GP300 is a two-way, high-frequency radio used for business and industrial purposes. It is powered by a rechargeable lithium-ion battery pack that attaches to the base of the radio handset. Over time it is possible for this battery to break apart. If this has happened to your battery, you can put it back together yourself.

Lay the two halves of the battery pack next to each another. One half will be the top cover and the other half will be where the individual battery cells are connected. These cells are connected via wiring to terminals in this part of the case. If one of the cells has become separated, proceed to the next step.

Plug in your soldering iron and solder the end of the wire running from the battery cell to the empty terminal in the battery compartment.

Line the outside edges of the two halves of the battery pack with hobby glue.

Fit the two halves together, making sure that the sides and corners of the two halves are flush.

Wait for the glue to dry and the battery pack will be rebuilt.
