The two batteries Hahnel differ significantly in their perseverance. Hahnel Battery # 1 has the feeling for about 20% less power than the Canon battery. Hahnel Battery # 2 makes unfortunately much earlier limp, I would say he has about half the power of the Canon batteries. As I said these are emotional values, the camera was used uniformly, WLAN getting out, no Live View, GPS always on.
With Hahnel Battery # 1 I am very happy, he makes a little less than the Canon Battery and costs while kanpp half.
Had I only Hahnel Battery # 2 but I would be very unhappy.
