I've been using the battery as a replacement battery for my Canon EOS-M, since this is quite fast through the empty display. This battery of Ansmann is compared to the original Canon battery much cheaper (around 1/3 of the price), but he also keeps a little shorter. He has only about 80% of the performance of the original battery. However, considering the price, so you can for the price of the Canon batteries directly 2 or more Ansmann buy batteries and then has more battery power in total. Therefore strong buy recommendation.
