Review on Rechargeable AAA Lithium Batteries With Micro USB Charging Port - 1000 Cycle, 1.5V/400MAh - Pre-Charged, 4/Pack by Becky Gilbert

Batteries always needed, even better if rechargeable. I like the fact that you can charge it almost anywhere a usb is available. I have a similar battery and it has served me well over a year and still going strong, so I am giving these a chance to see how these perform. I received mine in orange instead of blue and received a quick e-mail to explain the difference. A big thumbs up to the retailer. (Apparently orange has a red led when charging and green when complete. The blue battery indicates red when charging and turns off when charged). 1.5 volts as indicated compared to 1.2 volts of other rechargeables is the selling point for me. I’ve had low performance with 1.2 volts in the past. The downside for me is the small elastic band that attaches the cap to the body of the battery. Not a deal breaker but I wish it was magnetic like the other brand I have. Overall I like it.
