As ambassador, now I'm trying to Want more this charger and AA and AAA batteries. The charger has a fairly simple shape and can charge two battery types simultaneously if needed (2AA and 2AAA or 4 of each). The lights are red as not loaded, otherwise green. I found the first load a bit long but at the same time I installed a baby monitor with power backup battery in case of cut so impatient for commissioning (yes, I would have preferred pre batteries loaded as c This is the case for some brands ...) Now I do not know whether the batteries will hold over time, it is the complaint I was doing on the previous marks, after a moment, the batteries hold a charge longer ... To see in 1 year intensive use on children's games (for baby monitor, hope there is not too much power failure) A place to keep the already loaded for future use batteries would avoid seeing them lying in a drawer ... Otherwise product that is his role for the moment ...
