$39 is high to you considering how quickly that adds up when buying alkalines over time? I have read quite a few articles on the very subjest and from what I gather, it's very possible and quite safe PROVIDED the proper charging circuit is used. Mfrgs. place those warning labels on the batteries since the avg. home charger isn't capable of safely charging an alkaline as well as it would diminish new battery sales thereby keeping some money in our pockets.!! And we can't have that, can we?
