Battery vs capacitor

[v.s.n.kumar]

what is the difference between capacitor and a battery. what is the advantage of one over the other

 

[barry]

A battery converts chemical energy into electrical energy. A capacitor stores electrical charge.

 

[Audioguru]

A battery voltage stays fairly constant as it discharges.
A capacitor voltage drops very quickly at first then drops slower later as it discharges.

Some cheap batteries made "over there" are fakes: https://www.youtube.com/watch?feature=player_embedded&v=eOshOXcSkDA

 

[andre_luis]

Batteries store energy in chemical bonding, and although it is not a general rule, have a larger volumetric capacity of storing charges, compared to capacitors. Capacitors, on the other hand, store energy "physically" and generally have a greater life cycle if compared to batteries.
