Specifications of lithium ion cells

Nominal capacity- The nominal capacity (or rated capacity) of a Storage Component is the amount of energy that can be withdrawn from it at a particular constant current, starting from a fully charged state. The current used to rate batteries varies from one manufacturer to another, but it is typically either the 10-hour,…
