Impact Wrench Restoration DCA ADPB280

The DCA ADPB280 was nearly new and was run over by a car, causing a comminuted fracture. The battery cells were exposed, four cells were missing, and the wrench casing was damaged. Repair the plastic shell and reinforce it with magnetic nails and copper wire. The internal gearbox is almost brand new, and the grease has not changed color yet. It was simply wiped and re-greased. The battery part retains the previous protective board. After testing the previous battery cells, it was found that they were in near-new condition. I selected five cells and reassembled a 2.0ah battery. Eventually the wrench function was fully restored and the battery repaired.
