More milliamp hours should mean that it can supply more current for longer. (I should mention that the cells I have been testing are at, near, or beyond the end of their useful life -- for example, when new, the AAA cells I mentioned were rated at 1200 maHrs. -- the AA cells even more (2500 maHrs. for the one in question). I am testing to see if any can be rejuvenated and which should be saved and which thrown away (well, recycled).)
