Abstract
A method for reactivating and recovering electrolyte cells by drilling a hole through the battery case and injecting a volume of electrolyte liquid into the case for absorption into the cell separator material. The battery is subjected to multiple charge/discharge cycles while the cell opening remains unsealed, and is subjected to a final charge prior to sealing the drilled hole through the cell outer case.
