Ideal battery capacity | PVEducation
The battery capacity is a measure of the amount of charge or energy stored in the battery. The fundamental units of battery capacity is coulombs (C), although a more common and useful unit is Amp-hrs (Ah) (amps = C/time, so Ah = C/time (sec) x time (hrs)). The battery capacity in Ah can be ideally calculated from the weight/volume or number of ...
