How To Calculate Ampere Hour Rating Of Battery. E V I T. Meanwhile the same battery may safely provide 36 amp hours for a period of 100 hours.
As you might remember from our article on Ohms law the power P of an electrical device is equal to voltage V multiplied by current I. Re-arranging this equation and we find that Q EV. Drawing 10 amps from a 10 amp hour battery or 1C you will only get half of the rated capacity or 5 amp-hours from a 10 amp-hour battery.
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.
A single ampere represents a single coulomb of electrical charge which passes throughout every part of the conducting item within a second. For NiFe for example using Solar this could typically be. 1 week ago Jul 06 2021 If you want to convert between amp hours and watt-hours or find the C-rate of a battery give this battery capacity calculator a try. A rule of thumb is that for a 1 hour discharge rate ie.
