I have an Olympus battery charger that came free with my C700UZ Digital camera a couple of years ago. The model is BU-200.
My questions are:

1. Is it peak-detection/smart based or timer-based?

2. So far i have been using it to charge 1600/1800 mAh batts from Sony, GP and Olympus. Can it charge the Sanyo 2100 mAHs?
