I purchased two dewalt 18v batteries with charger. One battery lost a pair of cells,
opened. Purchased two after market batteries. One battery lost all but one pair of
cells. 4 cells were opened, 4 were shorted.
All the batteries had an electronic charging module which monitors each pair of cells.
They obviously didn't do their job. I see no need to even try rebuilding them. If the
factory can't get it right, what makes me think I can.
I've read cell failure is a common problem, along with thermal runaway.
IMHO, Li-ions are too expensive and too easily damaged. I'm batting 500, lost 50%.
The only way I would buy another Li-ion battery is to convert over to Rigid, which my
BIL tells me home depot warranties everything for life, including the battery. I don't
know if Rigid has all the cordless tools I have, like a grease gun, caulking gun and
rotary dremmel like tool. Besides it would cost mega bucks to change over. I have many
duplicate tools for my different locations. Just not worth it.
