Open the drill battery pack with a screwdriver and locate the chain of Ni-Cad batteries to be repaired. Pull these cells out of the Makita battery casing.

Determine how the cells are placed in line. Using a pencil and paper, jot down the polarity of the line of batteries. Note the pattern and how the cells fit into the casing for easier reassembly.

Test each individual Makita Ni-mh battery cell in the battery tester to determine which ones are bad. Mark the bad cells that will need replaced.

Purchase the same sized Ni-Cad replacement batteries. Only replace Ni-Cad batteries with Ni-Cad batteries. The type of batteries must remain the same throughout the battery chain.

De-solder the first "bad" drill Ni-Cad battery cell from the chain. Re-solder in the new Ni-Cad battery.

Repeat this process with the entire tool Ni-Cad battery chain until completely restored. Replace the chain within the tool battery case.

Place the cordless tool on the charger overnight and it should be as good as new.
