[QUOTE="WayneF, post: 499935, member: 12496"] I do know there are different kinds of chargers. :) Speaking frankly, the link you posted said $15 for four batteries and a charger. So that's a pretty cheap charger. A smart charger costs maybe $30 to $60, less batteries. Maha is a good charger brand. The cheap chargers are of a few types. Some just always charge at a low slow rate and never shut off. Some shut off after a constant time period, regardless of the battery size or the previous charge state. Not smart, but if the charge rate is slow enough, this doesn't really hurt the batteries if not overdone too often. Other faster chargers shut off when the batteries get too hot, which implies they are charged and have had enough. The good smart chargers have computer circuits to monitor individual battery voltage and state, and shut off individually when the battery is [B]actually full[/B]. These will have a status LED for each cell, monitored and controlled individually, what the battery actually needs. This could be up to a couple of hours for a really low AA cell, or less if the battery is not empty. [/QUOTE]
