Capacity
The amount of current that a fully charged battery can deliver.
It is measured in ampere-hours (Ah) and indicates how many hours (h) a battery can supply current at a certain level (Ampre/A). Therefore, the greater the consumption and the longer the vehicle or device is to be operated before it is recharged, the higher the Ah capacity of the battery must be.
This is especially important for traction batteries or supply batteries.
