Amp hours, also known as ampere hours, is a unit of measurement used to quantify the capacity of a battery. It represents the amount of current a battery can deliver over a specific period of time. Put simply, amp hours indicate how long a battery can sustain a certain level of current flow.
Amp hours (Ah) on a battery refers to its capacity to deliver a certain amount of current over a specified duration of time. It is a measure of the amount of charge a battery can store. How is amp hour rating determined?
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
Put simply, amp hours indicate how long a battery can sustain a certain level of current flow. An ampere, denoted by the symbol “A,” is a unit of electric current. One ampere is equivalent to the flow of one coulomb of charge per second. Therefore, an ampere hour (Ah) is defined as the delivery of one ampere of current for one hour.
For example, a battery with a rating of 100 Ah can deliver a current of 1 amp for 100 hours, or 5 amps for 20 hours. It’s important to note that the actual capacity of a battery can vary depending on factors such as temperature and discharge rate. Higher discharge rates can reduce the overall capacity of the battery.
When it comes to batteries, amp hours represent the total amount of charge they can hold. This measurement helps determine how long a battery can power a device before requiring a recharge. The amp hours rating of a battery directly influences its performance.
