Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
Batteries have not only a voltage rating, but an "amp" capacity rating. Dry cells, such as common flashlight batteries (or standard 9-volt batteries you are referring to) have a very low amp capacity. Wet cells, such as a 12-volt lead-acid car battery have very high amp capacities.
However, the amount of current we can really draw (the power capability) from a battery is often limited. For example, a coin cell that is rated for 1 Ah can't actually provide 1 Amp of current for an hour, in fact it cant even provide 0.1 Amp without overextending itself.
So if a battery has a nominal capacity of 500Ah and a nominal voltage of 12V, the overall nominal capacity in kWh is 500 * 12 = 6,000Wh, or 6kWh. Remember the battery only has this capacity when operating at the nominal discharge current … The power output of the battery in Watts is given by Discharge current (A)* Voltage (V)
How to size your storage battery pack : calculation of Capacity, C-rating (or C-rate), ampere, and runtime for battery bank or storage system (lithium, Alkaline, LiPo, Li-ION, Nimh or Lead batteries
So if our 500Ah battery has an operating current of 20A and an operating voltage of 12V, then it has a power rating of 240W. When sizing the system it is important to look at the likely power input (i.e. the excess solar power) and the required …
