How do batteries work? A simple introduction

batteries

For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.

How do batteries work? A simple introduction

The higher the voltage, the more current a battery will produce when it''s connected into a given circuit, which is why this kind of voltage is sometimes called an electromotive force (EMF). The power something like a lamp or electric motor produces (or consumes) is proportional to the voltage across it, so a bigger voltage usually means more …

DOE Explains...Batteries | Department of Energy

Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
