Everything comes from China products reviews site purchased in China
I was looking for in china a battery charger and I found in the streets of Uruguaiana, in the center of Rio de Janeiro. It was only 53 ha.and 25 ha beside, charger and four batteries.
Without doubt, 4300mAh cells are the best I've ever seen. Of course the 4.3, something near 6W, is something impossible, but these rechargeable batteries are quite good in relation to any other that I bought in China or anywhere else.
Despite the charger can also charge 9V batteries, do not recommend. 9V rechargeable batteries are all a drug. You can also download AAA batteries. Using the batteries and the charger on camera that I bought in Paraguay, but this is another story.
