Peukert''s law
It is a common misunderstanding [2] that the energy not delivered by the battery due to Peukert''s law is "lost" (as heat for example). In fact, once the load is removed, the battery voltage will recover, [3] and more energy can again be drawn out of the battery. This is because the law applies specifically to batteries discharged at constant current down to the cut-off voltage.
Battery Charging and Discharging Parameters
All battery parameters are affected by battery charging and recharging cycle. Battery State of Charge (BSOC) A key parameter of a battery in use in a PV system is the battery state of charge (BSOC).

How do you calculate a battery charge level?
Charger Current (A): The charger’s output current is typically measured in Amps (A) or milliamps (mA). To consider the current charge level, we multiply the battery capacity by the uncharged percentage. Effective Capacity (Ah) = Battery Capacity (Ah) × (1−Charge Level/100) Let’s say you have:
How do you calculate battery capacity?
If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour. In other words, you can have "any time" as long as when you multiply it by the current, you get 100 (the battery capacity).
