2 x LP-E8 battery LPE8 MP DSLR CANON EXTRA ® - Optimized Battery for CANON EOS 550D, EOS 600D, EOS 650D, EOS Rebel T2i, EOS Rebel T3i (Electronics)
Not bad self, almost equivalent to the basic battery 650D, but beware, the battery almost cut suddenly end of the cycle, there is no progressivity as on the original. Still, for the price, it is very correct.
