Cordless Drill Advice

[ezdays]

Thanks for the replies , guys .

Thinking back , I probably overcharged it at some point ....but how do you know when it's charged ?

It depends on the charger. Some, like the earlier 18 volt Harbor Freight ones had a charger that quite charging when it reached full charge. I had a couple of those, that's why mine lasted so long. There was a red LED lit when it was charging and a green one to let you know it was charged. It would not overcharge, unlike the newer ones that have just a red LED and no limit sensors.

It won't burn up a 12v drill by giving it 20v?

It would if it would fit, but I think he's talking about the whole thing, drill and battery. Not a bad deal with a lithium battery.
