Capacity is the leading health indicator of a battery, but estimating it on the fly is complex. The traditional charge/discharge/charge cycle is still the most dependable method to measure battery capacity. While portable batteries can be cycled relatively quickly, a full cycle on large lead acid batteries is not practical for capacity measurement.
energy loss rates attributable to all other system components (i.e. battery management systems (BMS), energy management systems (EMS), and other auxiliary loads required for readiness of operation). Self-discharge Rate (Section 5.2.5) Rate at which an energy storage system loses energy when the storage medium
of power and energy. • C- and E- rates – In describing batteries, discharge current is often expressed as a C-rate in order to normalize against battery capacity, which is often very different between batteries. A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity.

The easiest and most common way to test a battery''s capacity is to measure its voltage and current under load. Once the battery is fully charged first, a load is placed on the battery and then the voltage and current of the battery is measured. The energy coming out of the battery is counted and added up to form a capacity figure.
