When I placed my new camera in the cart, I was still the same place a spare battery to the course should be powerful, but did not have to be expensive. The reviews of this battery were very good and the price unbeatable. So clean it. Just in time for holiday travel everything was there. Unfortunately, the battery is made limp right after the second charging. The duration of benefits is extremely disappointing. So I'm in the next shop, had again decided against the original and for a cheaper replica and this time paid slightly more Euro. Lo and behold, wonderful. Conclusion of the seller: "Buy cheap, buy twice!"
