Last year I bought two Milwaukee drills: the 2601-22 18V Li-ion Compact Drill Kit and the Milwaukee 2401-22 12V Li-ion Sub-Compact Driver Kit. They take a different type of battery which involves two different chargers.
Last January we had some serious power surge problems (a squirrel had chewed through the insulation of the lead into the house) and I now discover that both chargers had been left plugged in (with spare batteries in them) and the chargers appear to be dead. Not sure about the batteries.

1. can these be fixed or do I need to replace the two chargers … they are expensive, about $50 and $80
2. are the batteries likely to be damaged also? I can’t tell until I try charging them.

I had the same probelm when a septic contractor broke the neutral wire to the house when he was putting in a new septic line to an addition. Fried every one of the battery chargers we had plugged in, from the laptop computer to the one on my cordless hair trimmer, the microwave was toast as well. The devices batteries were still fine, just had to replace the chargers. (actually the contractor paid for it all. Did your squirrel have insurance?) Get a new charger and try charging the batteries, I would think they work fine. Ours all did.

I did not find the body, but I suspect the squirrel found its well deserved reward with surge of electricity. We lost several appliances and the electrical company paid for everything. I had not checked the drill chargers until later, after I had filed the claim.
I went to take them apart to see if there was a fuse that might be replaced. They are screwed together with those star shaped headed screws for which I don’t seem to have a tool … as though they don’t want us messing with the insides. I found what I need for replacement at Home Depot for $49 each. I’ll be more careful about leaving them plugged in.
I also am having a whole house surge protector installed. This is closing the barn door after the horses have fled, I realize.

Star head screws (Torx)- just use a screwdriver that fits across two of the opposite slots. Best is to get new chargers and batteries. Just thought, rechargeable batteries can be rebuilt. Check to see if there is a Batteries Plus store close by or Google for the subject.

I also have a surge protector on the main power box. They are easy to install and not too expensive.

I’m finding chargers on Ebay, purported to be new out of the box, for about half the price at Home Depot, even including shipping, which is free in some cases. Batteries look to be considerable cheaper than HD also, but I’m hoping I don’t need those.
