Battery repair tip #powertools #repair #dewalt #milwaukee #makita #shorts

If your battery voltage drops below a certain range it will no longer charge however this can be fixed with a DC power supply. In an 18v or 20v Battery this will mean bringing your battery voltage up to around 17v if there are no other faults this will allow it to charge on its own charger. The one shown here is a dcb546 6ah however this will work on other flexvolt batteries 9ah 12ah 15ah or any other tool battery. This is the safest form of battery repair and recovery possible.
