Similar prob:? --2 year illness meant no charging of two gardening strimmer and cutter batteries. They now dead and dont respond to chargers. Would e.g. a 210 shot (like a defribulator) or similar do it? Or are the batt's dumpers?


If they're lead acid, I've heard of people applying relatively high voltage to them to get them going again, but it needs current limiting, multiple cycling and you don't get good capacity in the end.

NiCd and NiMH are practically unrepairable. There are 2 ways to fix them, but neither is really practical.

Lithium I'm not familiar with any repair mthods
