What type of batteries typically have a capacity rating measured in ampere hours?

The capacity rating measured in ampere hours (Ah) is commonly associated with storage batteries, which encompass a variety of battery types used to store electrical energy for later use. This measurement indicates the amount of current a battery can provide over a specified period, which is crucial for applications where power needs to be supplied intermittently or over a long duration.

Storage batteries, such as lead-acid, lithium-ion, and nickel-cadmium batteries, can all be configured as storage batteries, but the term is often used to refer to large-scale battery systems that provide energy storage solutions, such as those used in renewable energy systems or backup power systems. Thus, the correct association with the term “storage batteries” encapsulates the broader category where capacity is typically evaluated in ampere hours.
