When a constant voltage power source is applied to a lead acid battery the initial charge current is relatively high. The current will then get lower and lower as the battery state of charge increases. Voltage of course stays the same given the constant voltage power supply.
Using Ohms law, it would seem that the internal resistance of the battery is increasing as the battery gets charged. But since a battery is not a typical electrical load as I normally think of an electrical load, is it correct to say that the internal resistance of the battery is changing or is there some other term that is to be used?
Effective resistance maybe? Equivalent resistance maybe? Or ?
