BU-904: How to Measure Capacity
The reason for this is that the 25A current draw on the RC test will be higher than that used to determine the Ah rating. Because you will get more energy out of a battery if the total current draw is lower for a longer period of time (Peukert''s Law), your conversion will underestimate RC. Hope that makes sense.
