Can you use a Craftsman drill 19.2 volt battery in a 18 volt drill?

Answer 1

The bulb will light but it will be brighter that the wattage rating of the bulb. The higher voltage will shorten the life of the bulb by a very appreciable amount. It is not recommended to do.

Answer 2

Yes. It also depends on the tool, the fittings and the length of time you use it. The risks are that you may burn out the tool, or the battery may explode when the tool burns out. It is a risk, a small one, but still a probability to consider.

Answer 3

Typically, they plug on the battery is different between the different battery types. If the plug it compatible, the drill motor would run faster and hotter, likely reducing the motor life.

Answer 4

If it fits, it will work, but you'll be shortening the life of your drill due to the extra current flowing through it.

Answer 5

Not if you want it to last. Already at 18 V you're running at 50% over voltage, which is likely to kill it pretty soon.
