I use a lot of AA including wireless mouse batteries, radio ... The life of the battery is substantially equal to my NiMh batteries of 2850 that I have for several years. The big problem is that I can not use these batteries in my radio SANGEAN which only accepts NiMh, internal NiMH charger is provided for! I AA 2850 and 2800 for several years and I have no HS stacks. By cons I am not satisfied with the preloaded new Ready 2100 mAH that take much less. Considering the price of these lithium ion batteries, I expected a useful life of at least twice that which is not. Maybe for some applications this purchase can be justified. I also hope not wrong charger to charge two different types of batteries. Further recharging is very long with this charger.
