What is the theoretical output of a 100 ampere-hour battery for 5 hours?

The theoretical output of a 100 ampere-hour battery can be understood through its definition. An ampere-hour (Ah) rating indicates the amount of current a battery can provide over a specified period before it is fully discharged. In this case, a battery rated at 100 ampere-hours means that it can deliver a total of 100 amperes for one hour, or any combination of current and time that equals 100 Ah.

To find the current that the battery can theoretically provide over 5 hours, we take the total capacity of 100 Ah and divide it by the duration of 5 hours. Performing this calculation gives us:

100 Ah ÷ 5 hours = 20 amperes.

This means that to sustain a usage of 20 amperes over 5 hours, the battery will utilize its entire capacity, which is what we expect given its specifications. Therefore, the theoretical output for a 100 ampere-hour battery over 5 hours is 20 amperes.
