Will it work on ones that wont hold a charge at all?If anybody cares if you have a going dead lithium battery that need charging all the time. Take a battery charger to 40 and with two wires in the jaws hit the postitve and neg on the battery terminals.
Lithium batteries that need a charge all the time have crystals that form and suck the juice out of it. Hit them with a battery charger and they work great again for a while, then when they do it again, hit them again.
My bud who uses dewalts for plumming does this trick if it helps anybody.
