A Guide To Understanding Battery Capacity
Knowing the discharge current and the discharge duration, you can calculate battery capacity (in Ah) as follows: Charge Capacity (Ah) = Current (A) x time (h) This way, "Amp-hours" (or Ah) …
What if the current draw is greater than the rated discharge of a battery?
You''ll see that the voltage vs. amp-hour curve is very flat for the most part, meaning that once the battery reaches about 3.3V, it''s already at nearly 100% capacity. Sure, if you charge up to 3.5 or 3.7V, you''ll gain some extra capacity, but it will be at diminishing returns, (ie. you might only get a couple extra % of capacity out of it ...
