How much power does a 12 volt battery provide?

The American National Standards Institute (ANSI) states that a 12-volt battery provides sufficient energy to crank the engine. Battery capacity, measured in amp-hours (Ah), indicates how much power a battery can supply over a period. For example, a 70 Ah battery can provide 70 amps for one hour.

How much energy can a battery store?

This does not directly tell you how much energy the battery can store, but can be a more useful value in deciding how long a circuit will run from a battery. For example, a car battery might be rated for 50 Ah. That means in theory it could source 50 A continously for 1 hour and then go dead.

Why is a 12 volt power supply regulated continuously?

This is done continuously to compensate for input voltage variations and variations in the current the load is drawing.
