[QUOTE="condor22, post: 114296, member: 1932"] To clarify a PM sent to me. A device will have an amp (A) rating and an amp hour (AH) use. I'll go back to the Engel; It may be rated at 3.2 A, however it is not on all of the time (as in my 20 deg day example) At 20 deg in my 4x4 it averaged 1 AH (rounded) However, something like a TV that is rated at 3A will use 3AH and if on for 5 hours will use a total of 15AH So the difference between A and AH is; [b] A is what it is rated at and uses when on.[/b] [b]AH is what is uses per hour or the total over a given time.[/b] (Some also use W and WH, the math using the previous formula will give the same information, but I'll not confuse) [/QUOTE]
