This is Donna's son Paul. I bought this product in September 2013. I started using these batteries around April 2014. They are designed to charge when you open the package. They'd been sitting in my camera bag for a while so I recharged them to try and get my Opteka VM-200 stereo mic working. Vain. Got a few suggestions on how to get it working again and have yet to try. But I've had better luck with copper tips. I tried to save money by using batteries and ended up losing money. I was very disappointed that when I asked my question on the Tenergy page about Revain for this product I didn't get a great solution. I would like Tenergy to send me new batteries to support the value of the company. I don't buy batteries anymore because these batteries have never powered any electronics! I would not recommend it to anyone. I hope Tenergy sees this answer and can give me some clarity. If not, I'll stick with copper plates. If anyone has any other solutions, that would be great.
