Any hope for dead Lith-Ion batteries

[Woodwackr]

Well yes and no.
Yes both of the dead ones took a charge but they do not hold it a long time.

And...you're still alive

And...you're still alive

Barely......

I got raped Friday by a plumber
Then this morning his secretary called and said I owed more.

Repack them, gives You a second chance at popping a couple cells.

Neighbor: Batteries won't charge!
Me: Are You serious?
HINT: Compare the middle contact.

I have repacked the old 18v dewalt. Just solder the batteries in a Swiss and you were good. The ones I rebuilt are still all good

There are guys on eBay that sell what they claim are adapters to use 18v Milwaukee batteries on Porter Cable tools.
They do not work

I’ve heard good things about the adapters. I use 18 to 20v dewalt adapters regularly. Never used batteries from a different tool though. I thought for sure they’d work though

Well, he obviously didn’t, 1. Push hard enough, 2. Use a hammer.

Last summer my wife and I happened to take a once in every 3 years trip to 'the Mart'..
I happened upon this and thought for the price it could live in our 5th wheel for the rare time I could use a drill and not have to pack my drill from my garage..


Got it home, went to charge the battery and the charger flashed error.
I put it back in the box, it got shuffled around and forgot about.
I found it in my shop while looking for something else and took it with me to work today.
I was talking to a buddy in the body shop and he saw it sitting on my bench. Told him the story..
He went and got an adapter for a Dewalt battery that has a switch and 2 leads he uses for window motors and such on cars that he's repairing.
We momentarily touched the leads to the dead battery, put it back on the charger and it's currently taking a charge.

Classic jump start just so the charger recognizes and accepts the battery.

That was cheap, fingers crossed You get a bit of work out of that set.

I have adapters to use new Milwaukee batteries on old Milwaukee tools. They work fine, but I have to remember to disconnect the battery, or it will drain low enough that I have to jump it.

I fixed some male spade plug ends onto a couple of wires to do the jump from another battery.

I’ve heard the same with dewalt
