The amount of energy a battery can hold is measured in capacity. Capacity is the leading health indicator that determines runtime and predicts end of battery life when low. A new battery is rated at 100 percent, but few packs in service deliver the full amount: a workable capacity bandwidth is 80–100 percent.
As a battery nears the end of life, the internal resistance shoots up and capacity also decreases. Prior to that, internal resistance is flat, so there is no way to determine mid-life how much capacity/life is left in a battery using internal resistance as a guide; not until it …

"Professional" battery SoC calculation is done by integrating the area under the current-vs-time curve, essentially to count how many coulombs of energy is going into or out of the battery, & comparing that to either (a) the theoretical/designed coulomb capacity of the battery, or (b) keeping track over long periods of time how many coulombs ...
It refers to the amount of energy that can be stored in the battery, and can be determined by multiplying the current (in amps) by the time (in hours) that the battery can supply that current. For example, a battery with a capacity of 1000mAh can provide a current of 1000mA for one hour, or 500mA for 2 hours, etc.
As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time: E = V × I × T. Hopefully, you remember that amp hours are a measure of …
