A battery power supply works by converting stored chemical energy into electrical energy. When a device is connected to a battery, the electrical energy is delivered to the device, allowing it to function. The battery continuously supplies power until its chemical energy is depleted, at which point it needs to be recharged.
In industrial applications, batteries are commonly used as a backup power supply during power outages or as a primary source of power in remote locations. The output power of a battery depends on its capacity and the rate at which it can discharge energy.
The proper units of power (= instantaneous work rate) for a battery is Watts. The proper units of energy (= work done or doable) for a battery is Watt.seconds or Joules. If we work for one second at a power of one Watt we do 1 Watt second of work or 1 Joule of work and use 1 Joule of energy.
Batteries are used to store chemical energy. Placing a battery in a circuit allows this chemical energy to generate electricity which can power device like mobile phones, TV remotes and even cars. Generally, batteries only store small amounts of energy. More and more mobile devices like tablets, phones and laptops use rechargeable batteries.
Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).
The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. 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.
