Putting it simply, the way a battery works is that it converts chemical energy into electrical energy. a battery is made up of one or more voltaic cells. Each cell has a negative and positive terminal which do not touch. Each - the negative and positive - terminal is immersed ina solid or liquid electrolyte.
The electrolyte is a conductor. Chemical energy is converted to electrical energy by a chemical reaction. During this chemical reaction, a charge is transferred between the electrolyte and electrode.

Batteries made of voltaic cells are rated in volts. Alkaline and carbon-zinc are rated at about 1.5 volts (each cell, not the entire battery). However lithium cells can provide as much as 3 or more volts. However, they are a more hazardous battery. Manufacurers use a standard method to determine how to rate their batteries. The battery is discharged at a constant rate of current over a fixed period of time, such as 10 hours or 20 hours, down to a set terminal voltage per cell. So a 100 ampere-hour battery is rated to provide 5 A for 20 hours at room temperature.
