Can not write much more than that the batteries in my Olympus SH-50 fit and work here. Are been charged very quickly with the charger (about 1 hour). Charger was well packaged together with accumulators. The capacity is 950 mAh as indicated. I can not say anything about the difference to the original battery, because not yet been thoroughly tested. If in the "long-term" test new knowledge, I will report here. So far buy recommendation!
