How a battery works

Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device for. A high-capacity battery will be able to keep going for a longer period before going flat/running out of current. Some batteries have a sad little quirk—if you try and draw too much from them too
