You need a 2,400Wh battery. Given that most batteries run on 12V voltage, that means you will need a 200Ah battery to power a 400W device for 6 hours. To help everybody with these calculations, we have designed a 12V Battery Amp Hour Calculator.
To calculate a battery’s amp hours, divide its watt hours by its voltage. Formula: battery amp hours = battery watt hours ÷ battery voltage Abbreviated: Ah = Wh ÷ V Calculator: Watt Hours to Amp Hours Calculator
The capacity of a battery is the amount of energy that it can store. A battery's capacity is expressed in amp hours (Ah), which is a measure of electrical current over time. One amp hour equals one amp of current flowing for one hour. The higher the Ah, the longer the battery will last.
The Ah rating of a battery is just another way of describing the number of amps that a battery can produce in 1 hour. A 20 Ah battery will produce (in theory) 20 amps in 1 hour. However, there is also another system of labeling batteries and their discharge and longevity. This is described as the ‘C’ rating.
» Electrical » Cells Per Battery Calculator The Cells Per Battery Calculator is a tool used to calculate the number of cells needed to create a battery pack with a specific voltage and capacity. When designing a battery pack, cells can be connected in two ways: in series to increase voltage, or in parallel to increase capacity.
