Ok before anybody says use the search, I did and I still didnt find my answer. I bought one of these chargers today and a pack of Powerex AA's. I already had some Powerex and Eneloops that I had been charging with the Eneloop charger. The extremely rude guy at the battery store said all you have to do is put in on the Charge setting and it will do the rest. This thing is asking for charging rates and blah, blah, blah. I have no Idea in what I am doing. I bought this as it is supposed to be one of the better chargers and also has the function of bringing older batteries back to life. Can someone point me in the right direction or at least reccomend some reading for the electically challenged? None of numbers that this charger is giving me are close to the batteries capacities. (Eneloop 2000mah, Powerex 2700mah, Duracell 1800 mah, Moster cable 1500 mah ) the eneloop and powerex are new batteries (less than a month old) so I know they are not shot. Any advice would be appreciated.
