I already knew this brand because I have 2 chargers (Sanyo) +12 2000 mAh battery (Eneloop)! In fact, we take the same (so to speak) and start again only better !!! These batteries are simply the very best on the market at this price! That's what I feed to my SLR, my flash and a flashlight ... A sacred power that hard, hard, hard ... even when idle, they meet present at the slightest! Once they are fully charged, you can forget the several weeks they will still be on top after this time! I loved the "old", very good products, there, the bar has been set even higher! So I will replace all my 2000 mAh by them but without part with it! I will keep the less powerful for a mouse and other remote controls that are less energy! A top purchase for batteries that do not let you down anytime soon! Five stars justified for a quality product in tune: A must, especially for photographers! I do not know what gives the new Charger, but I think it would be good to take a look if it is the same quality and as good as these are Eneloop! Battery I recommend around me, no problem ...
