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.
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
An electric or battery drill that you hold in your hands.
The size of an electric drill is primarily determined by its chuck size, which indicates the maximum diameter of the drill bit it can accommodate. Common chuck sizes include 1/4 inch, 3/8 inch, and 1/2 inch, affecting the drill's versatility for different tasks. Additionally, the drill's power, measured in amps or voltage, influences its size and performance capabilities. Overall, the combination of chuck size, power, and design features determines the drill's overall size and suitability for various applications.
Most handheld electric drill are "portable" - the most portable are those that run on a battery. A hand help drill can be used to make holes in wood, metal or masonry. so that things can be joined together with screws. Many portable drills will also have an attachment to drive screws too.
Remote controlled: buy a cheap RC car and steal RC circuit from it: use circuit output to close a relay controlling the drill motor. More power: if the drill has a torque switch, set it to the most torque (slowest speed for pull of the trigger). If not, add external gearing to accomplish this.

Can be anything from 7.2 to 18 volts. Even more for impact drills. Less for the palm-sized and screwdriver sized ones.
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.

A cordless drill typically converts electrical energy from the battery into mechanical energy to rotate the drill bit. This transformation allows the drill to perform its intended task of driving screws or drilling holes.
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.
This model # shows as a black&Decker cordless string trimmer.
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.
The average speed of a cordless drill is measured in RPM (revolutions per minute). It can vary depending on the model and type of drill, but common speeds range from 500 RPM to 2000 RPM for most cordless drills.
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.
