There's not too much to say, I use these in my DSLR and in my handheld gps. I was messing with rechargeables but those eventually stop charging and need to be replaced, even with a high quality conditioning charger. Decided I wanted to find a as many Lithium's as I could at the best price and this was it. Electronic equipment lasts forever with these battery's in, and I only have to bring one spare set for my camera on extended backpacking trips.Get more detail about AA Ultimate Photo Lithium Battery 24 Battery Bundle.
