You melted a crystal which was shorting a cell ( or crystals shorting cells). It's like blowing a fuse.
Don't expect much more life from the battery though.
Once those batteries start to give out, and it happens depressingly quickly, they are done.Quote:

Most battery packs can be rebuilt either by specialists or at home. Inside, they are just commercial cells soldered together.
Some research will help with this one, as to the type, quantity and cost of cells.

Use the freezer to revive your battery.

I just bought a Ryobi drill today. It has 2 One+ 18v NiCad batteries with it. That matches my string trimmer with a 18v LIon battery, so I have 3 to use.
You can get really good NiCads at a hobby shop, and replace them yourself.
Any update? Did it work at all?Quote:

I would have played with it more but after subjecting one of my drills to hours and hours of run time to discharge the battery it didn't seem like the smart thing to do from a long term financial standpoint.Quote:

You get what you pay for and in this case the price is right but If you bought the kit at a Box store the batteries are seriously underpowered.
Assuming it's a one+ Ryobi, you can get Li-Ion replacement packs. I bought one of the larger capacity one from the orange borg for less than $100. Also bought that 6 slot dual chemistry charger. It doesn't charge all 6 slots at once, but for me that's a plus. It let me retire my homemade charger control station with the 12 hour timer.
