I picked up a pair of the apple batteries/charger for use with my magic mouse and wireless keyboard. I still had some juice in my current batteries so charged each set of two batteries for 24 hours and then put them in a drawer. Fast forward two weeks and my magic mouse has reliably run out of juice and when I put in two of the batteries, my mac states the charge at 74%. I've read in some of the other posts that because of the way NiMH and alkaline batteries differ, it is normal to have slightly lower ratings, but 74%????? Most people reporting stated they got 85%, has anyone else gotten 74% on first run? Are these batteries defective or is there something about my charging routine that caused them to be so much lower? Please advise.
