Yes, they are. The source is different from those that you would plug into a wall.

What is a battery and how does it work?
a battery is a acid full piece of medal that helps electric powered things when you connect wire on each side.
How can a battery be used to make things work?
Batteries can be used as a means by which electrical components may be powered such as a flashlight , an electric motor and a laptop computer .
Are battery operated things illegal?
Most battery powered objects are totally legal. It's only a few battery powered devices that are illegal.
Can you make battery acid with orange juice?
No But Some Things Can Be Powered By Juice If You Connect Something To It.
What do battery cells do?
A battrey cell charges the electric things like torch,electric toy etc.
A static discharge differs from an electric current discharge?
I believe this answer that each of these two are powered by different things.
What was the first self-powered vehicle?
What was the first self-powered road vehicles? Self powered can mean many things. A horse and chariot is a "self powered vehicle" for example. Over 2,000 years ago. If self powered means it "generates it's own power", a sailboat qualifies. Probably over 1,000 years ago. Later vehicles that generate their own power include: First electric self powered car, about 1970 when photovoltaic panels were introduced. First electric self powered boats, about 1980. First electric self powered airplane, 2007. For a growing list of self powered electric vehicles, see http://www.selfpoweredelectricvehicles.com/
Why some things need mains electricity and others need battery?
Portable devices that do not consume large amounts of power can be run on batteries. Some battery powered devices can also be powered by mains - running a 'battery eliminator' - to save from having to purchase batteries. Devices that consume large amounts of power are usually best powered by mains.
Why is it important to know about electric currents?
If you use stuff powered by electricity, you are very likely to eventually have to understand a bit about it. It'll tell you what can be plugged into a regular outlet w/o blowing a fuse. What can be run off a certain extension cord. How long you can run something off the battery in the R/V Before the battery goes flat. Things like that.
Why is electricity considered an infrastructure of development?
cos almost all things works by electric
Can you make a solar powered battery?
Kinda-sorta, but not very well. Batteries are fairly small, and photovoltaic cells - thin, black things that turns sunlight into electricity - aren't that efficient. You'd have to leave the battery sitting in good sunlight for quite long to get the battery recharged. Better then to use a solar powered charger, with a bigger collecting area and faster operation.
Why is a battery more useful than main electricity?
Since battery power involves electricity, I guess the question should be "Is battery powered more efficient than mains (or grid) powered?". Battery as well as grid, is a way of transporting electric energy. So the question is which is more efficient. At first glance it is easy to say that transportation via grid can be as high as 99,9% efficient when the distance is no more than 100 m, and can be as low as 88% when the distance is at the range of 1000 km. The efficiency of the transportation of the electric power via battery is maximum at the range of 90% (since there is always at least 10% of the power left in the battery).
