Already placed an order with ASBERO.GMBH for these batteries last June and I have to renew my order! These batteries are excellent and handy! Charged this summer for a very greedy Canon flash with a rescue game, I have not used for three months. I restarted the flash and the batteries were always on top, autonomy has not changed, same as immediately after the initial charge! Brief just load them, leaving them in the device and forget without fear that the device is not ready at the right time! Apart from a slight price increase since June is good stuff. For ASBERO society is the rapid, economical, without a igh (the German rigueure no doubt). Thank you again for Amazon which provides as usual. When I try something, I type "Amazone.fr" and takes me over the head, as in time for Christmas gifts, so much more convenient!
