What does ah on the battery mean?

Although it can be simply understood that 1Ah is 1A discharge for one hour, in fact, it can not be achieved
Ah is a unit to measure the capacity of a storage device. It must be a battery. It means that the product of current [ampere] and discharge time [hour] can be the result of capacity unit [ah] when it conforms to the discharge curve (a similar inverse proportion curve)

What's the meaning of "ah" for electric bicycle battery and its calculation method

The rated capacity of battery C, unit ampere hour (ah), is the product of the discharge current ampere (a) and the discharge time hour (H). Because the ah obtained by different discharge parameters for the same battery is different, in order to describe, measure and compare the battery capacity, unified conditions must be set in advance
