Hey guys,

My Craftsman Nextec 12v Li-on battery is dead. This battery is nice because it has a LED flashlight built into the base of the battery so in my mind it’s worth salvaging. The 3.7v cells are cheap on ebay….about a $1 each. I am trying to replace the cell(s) my self but I just can’t get the li-on cells out of the plastic case without further damage to the case itself. Looks like the battery is in a inner case that is snapped into the outer casing. I’ve tried yanking on the battery itself with not much success. If you have some wisdom in this matter..I’d love to hear from you. If I can get the battery out, I’ll do a writeup on how to do it.

I believe they’re glued/epoxied in place.

I just pulled open the Nextec 12v battery, there is no glue or epoxied. Just pull the bottom out. I am planning to replace the cells too. Hope to see your instructions.

Have your say...
