I would never buy a no-name battery from the Far East. Have I gained him as a second battery. After several months, however, he was no longer functional. My camera showed after 2 photos that the battery is dead and has gone out. Shortly before I had him but always fully charged (it had frequently tried, then my Canon battery grade). Here I am going but probably only buy in future Canon batteries, even if it has to reach a little more in the pocket. In addition, it is ensured that you might not even damaged the camera with the cheap imported! However, I have the company great credit that they gave me after my complaint - has for more than a year, without hesitation sent a new battery!
