What Is Battery Storage Capacity?
Storage capacity (also known as energy capacity) measures the total amount of electricity a battery can store. The spec indicates how much electricity a battery can deliver over time before needing to be recharged. This metric is usually provided in watt-hours (wH) or kilowatt-hours (kWh) for larger batteries.

At this point, it''s worth noting depth of discharge. This refers to the amount of battery capacity you can use safely. For example, if a 12kWh battery has an 80% depth of discharge, this means you can safely use 9.6kWh. You should never use your battery beyond its depth of discharge as this can cause permanent damage.
