Rechargeable batteries are recharged by reversing the chemical reaction that occurs within the battery. But a rechargeable battery can only be recharged a given amount of time (recharge life). Even iPods, with built in batteries, cannot be recharged forever. Moreover, each time a battery is recharged, its ability to hold a charge goes down a bit. Non-rechargeable batteries should not be charged as various harmful and harmful substances can leak out, such as potassium hydroxide.

The cells can be connected to make a bigger battery. Connecting the positive of one cell to the negative of the next cell is called connecting them in series. The voltage of each battery are added together. Two six volt batteries connected in series will make 12 volts. [3]

Connecting the positive of one cell to the positive of the other, and the negative to the negative is called connecting them in parallel. The voltage stays the same, but the current is added together. Voltage is the pressure pushing the electrons through the wires, it is measured in volts. Current is how many electrons can go at once, it is measured in amps. The combination of current and voltage is the power (watts = volts x amps) of the battery.

AA, AAA, C, and D cells, including alkaline batteries, have about 1.5 volts. The voltage of a cell depends on the chemicals used. The electric charge it can supply depends on how large the cell is, as well as what chemicals. The charge a battery delivers is usually measured in ampere-hours. Since the voltage stays the same, more charge means a bigger cell can supply more amps, or run for a longer time. History [ change | change source ]

The first battery was invented in 1800 by Alessandro Volta. Nowadays, his battery is called the voltaic pile. [4] In many modern batteries, the fluid is "soaked up" in a kind of paste and everything is put in a completely sealed case. Because of this case, nothing can spill out of the battery. An exception is car batteries; they still have liquid inside. Types of batteries [ change | change source ]
