Battery capacity is measured in Ah, or Amp-hours. As the name suggests this means how many amps the battery can deliver in an hour. For example, a 12V lithium battery with a capacity of 100Ah can deliver 100A to a 12-volt device for one hour. The same 100Ah battery could supply power for 4 hours (100/25=4) to a 25 ampere device.

How to calculate battery watt hours?
Now, to calculate battery watt hours, we will need only 2 key metrics: Amp hours (Ah). This is your 100Ah battery, for example. Voltage (V). Most batteries have a 12V voltage. Some bigger batteries can have 24V or even 48V voltage. Fortunately, all batteries will have both Ah capacity and voltage prescribed on the battery itself (or the label).
What is a watt hour calculator?
Our watt hour calculator allows you to use electric charge in milliamp or amp hours and voltage in volts to calculate the energy in watt-hours or joules. Amp hours – the shortened name of ampere-hour – indicates how much charge can flow through a battery per one hour.
What are amp hours in a battery?
Amp hours – the shortened name of ampere-hour – indicates how much charge can flow through a battery per one hour. More specifically, it is an electric charge in a battery that enables 1 ampere of current to flow for one hour. For standard AA or AAA batteries, you do not need to use amp hours, as their rating is provided in milliampere-hours (mAh).
What is the difference between Ah and watt hours?
Ampere-hours (Ah) represent the amount of charge a battery can deliver in one hour. For instance, a 1Ah battery can deliver 1 amp of current for one hour, or 2 amps for 30 minutes. On the other hand, watt-hours (Wh) denote the total amount of energy a battery can deliver over time, considering both voltage and current.
How many watts are in a watt-hour?
One watt-hour is the amount of energy used by an appliance with a power rating of 1 W that is used for one hour. For example, suppose you had a 25-watt light bulb in your lamp and kept it on for 4 hours. It would consume 100 watt-hours of energy. Use the watt-hour calculator to obtain watt-hours from amp hours or time.
What is a high watt hour battery?
Think of it like this: a battery with a high Watt hour but low Amp hour could run a small gadget for a long time, while a battery with a high Ah but low Wh could run a big machine, but only for a short while. Watt-hours, or Wh, is a measure of electrical energy.
