Can be anything from 7.2 to 18 volts. Even more for impact drills. Less for the palm-sized and screwdriver sized ones.
They used to be either Ni-Cd or NiMH, which made the cell voltage 1.2V. These days they can be Li-Po / Li-Io, which have about 3.6V cell voltage.
Probably not. The cordless drill will, at best, see the battery as nearly dead; it probably won't work at all.
The volts on cordless drills are based on the battery power. The volt rating reflects the battery that is in the drill.
There are only a few parts and components that separate a cordless electric drill from a corded electric drill. Having a battery instead of a cord is the biggest difference.ÊÊ
NASA needed a way to drill under the moon's surface. So they invented a cordless drill, and soon after many other cordless tools, that was lightweight, small, and battery-powered.
That's a tough task for a battery operated tool. You really need a hammer drill. There's a nice Milwaukee cordless hammer drill at Sears but it costs $350. My corded hammer drill cost only $79. To me that is a huge difference for the convenience of cordless.
This model # shows as a black&Decker cordless string trimmer.
Probably from ebay, Amazon, or the Challenge website.
A person can get a battery charger for a Challenger 21.6 cordless drill at most local hardware stores or directly through the manufacturer. Over time the batteries will slowly lose their ability to charge and require replacement.
If you are referring to a small 12 volt battery as used in a cordless drill, the answer is no. Those batteries do not have near enough amps to turn over a vehicle engine.
Absolutely not! It is a 14 volt drill. Use a 16 or 18 volt battery will destroy the drill in short order. It will run but not for long.
From what I can find, it doesn't look like they sell them anymore.
