It this an old makita with a tower battery?Ditto that.
I've been burned by a fake Li-ion Makita battery, just yesterday. Wouldn't take a charge and it had only been used a few times.
It was a couple of years old and I'd left it too long between charges. Even so, I felt a bit short-changed.
While it worked, it was impressive enough, though. Far better than the NiMHs I'd been using.
Think I'll have to bite the bullet and buy the real thing.
Get or make an adapter and use modern slide on batteries.
Either genuine makita or lidl x20v batteries.
