FAQs about Relationship between energy storage battery capacity and rated capacity
What is rated capacity of a battery?
The energy that a battery can deliver in the discharge process is called the capacity of the battery. The unit of the capacity is “ampere hour” and is briefly expressed by the letters “Ah.” The label value of the battery is called rated capacity. The capacity of a battery depends on the following factors:
What is the difference between theoretical capacity and rated capacity?
