48 grams of Amazom

I ordered my battery at Amazon (not a marketplace dealer, I try whenever possible to order directly from Amazon). I got a battery that packs in a Canon-blister packaging incl. Hologram came along. Now that I've read about some fake batteries here, I put the battery pack immediately after unpacking our digital kitchen scale. And this was at 48 grams. I think the remaining 2 grams are negligible and it is this is an original battery. I could see on the housing no difference to the original battery supplied my EOS 550D. Otherwise, the price is right. Delivery as Amazon accustomed very quickly.
