Rated AH capacity is at 25˚C (77˚F).
The capacity of a lead-acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert''s law.
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.

In general, the higher the Ah/mAh rating of a lead acid battery, the higher its capacity. For most 12V applications, lead acid batteries with a capacity of over 20Ah/2000mAh must be in place for adequate performance. With knowledge about lead acid battery capacity, users can make an educated decision on which battery best suits their needs.
A lead acid battery goes through three life phases: formatting, peak and decline (Figure 1). In the formatting phase, the plates are in a sponge-like condition surrounded by liquid electrolyte. ... Some …
Electrolyte Condition / Specific Gravity. The liquid electrolyte needs to be kept in proper condition in two ways, in the following order: 1) The specific gravity of the electrolyte needs to be tested, using a good-quality battery hydrometer, and 2) The fluid level must be maintained in each cell so that the tops of the lead plates are never exposed to air.
