What Does The Ah On A Battery Mean. This is the total amount of charge a battery can deliver in one hour. Ah is the short form of ampere-hours and shows the amount of power that a battery can store and give over a given time.
This describes the charge capacity of a battery or how much current can be delivered at a constant rate as the battery is depleted over the course of one hour. The average car battery will have an Ah rating somewhere around 50Ah. Wondering what in the world Ah Amp hour means.
The C rating tells you how many amp hours the battery can provide for a very specific period of time.
This is directly correlated to the amount of life the battery will have during its time in use. Having this knowledge makes it relatively easy to tell the capacity of a deep cycle battery. Most deep cycle batteries will tell you the Ah rating at multiple C ratings. The Amp Hour also has sub-units like the MilliAmpere-Hour mA-h or mAh and the MilliAmpere-Second mA-s which is the unit of measure used in X-ray diagnostic imaging and radiation therapy.
