Yes it is. It is a source of electromotive force(otherwise known as electromotance)that tends to cause current (electrons and ions)to flow.
The two most common sources of electromotive force are batteries and generators. Batteries convert chemical energy into electrical energy, while generators convert mechanical energy into electrical energy.
Yes, MacBooks use lithium-ion batteries as their power source.
Yes,because AA batteries are also a source of electricity and a source of battery can replace LR 6 battery..:))
Batteries are a source of direct current because they product power (voltage and current) in only one direction.
They utilize the power of the force concentrated through a crystal, not batteries.
Simple source of direct current are Batteries.
Headphones do not use batteries, they use a power source such as an iPod or mobile phone.

Batteries, Battery, Automotive Battery, and a Car Battery
yes, unless they're dead.
Batteries Plus is a good source.
Batteries provide a voltage difference.
