Best Answer

Batteries make electricity by a chemical reaction. Eventually the reaction completes and the battery is said to have run down or gone dead. A car's alternator or generator charges the battery by reversing the reaction while the engine is running.

What does a battery use to make electricity?

Batteries do not generate electricity; they only store a charge that is generated elsewhere. After that charge is used up, they need to be recharged or replaced.


Why don't we get most of our electricity from batteries?

Batteries can only store electricity, not create it. Batteries can only store and release direct current (DC), while power plants produce alternating current (AC). Since it takes up a lot of space and it costs a lot to use batteries, the batteries might not be able to store all the electricity that is produced. This is why an electrical generating station does not use batteries to generate electricity.


How batteries produce electricity?

Do crank flashlights take electricity?

Sure they do. Only difference is that you generate it yourself by the crank rather than buying it pre-packaged in batteries.


How do you conserve wind energy?

Wind energy, or rather, electricity produced from wind energy, can be stored in batteries. It can also be used to pump water uphill. This water can then be used later when needed to generate electricity (hydro-electricity).


What are the uses of solar panels in your day-to-life?
