The Ansmann Battery BP 511 runs with me properly and without any problems. It can be just as fast upload and exchange as the original battery by Canon. I use the spare battery in a Canon EOS 40D and really notice almost no difference which battery plugged straight into the camera. A spare battery is actually essential for each camera. Because the matching Augenblich can quickly leave an otherwise of current and thus the possibility of receiving NEN good snapshot. On trips or on vacation one should always have him there. Price Leistungsverhäktnis also true. From there her I can really recommend this part ...! 5 Stars
