Has anyone had trouble with tenergy batteries? I bought some with hopes to use them for trail cameras, and was using them in the kids electronics first to test them. I bought 26, and at least 10 wouldn't take a charge after the first cycle. What could cause this? I emailed tenergy, and they would need me to send them back to test them. The amount it would take me to ship them, I can buy another set. Is this common with tenergy rechargeables? Is there a better brand out there?
