Given that the Olympus standard BLS-1 battery is only 1150 mAh and there are after-market batteries of up to 2000 mAh, one might hope that some of these would improve the shot capacity of the camera. But there's a lot more to battery life than that number.
So, has anyone had success with another battery manufacturer? (Strangely I found little with a search. I would have thought this to be a FAQ.)
