I have had my Canon 5D Mark 2 for about 5 months now and wanted to get an extra battery for back up. I have been searching the web trying to find an aftermarket replacement at a realistic cost as it annoys me that Canon seem to want to extract every last penny from their customers when it comes to replacement battery's.
I had real trouble tracking one down but have managed to find a company online who supply them so I thought I would share this information with all the 5D 2 users out there.I'm in the UK and I bought mine here : http://www.digitalmediastore.co.uk/batteri...__WIN-CAE6KIT-D for £24.90 which included the battery/mains charger and car charger lead with delivery included. Place that against the official Canon battery at about £65.00. Now, before you rush off and buy them I would point out that this battery ( unlike the Canon battery ) doesn't have a chip which communicates with the camera to show the battery life, so when you first install the battery in the camera you get a message on the screen telling you this and asking if you still want to use the battery, pushing yes will get you using the camera as normal. I used the battery all day yesterday shooting about 600 raw files with regular screen use and it hadn't run out. Obviously I should point out that I have no commercial or other ties with the above store, I just hope I have saved a few other photographers some hard earned cash in these hard times.
