I am looking to purchase an inexpensive battery charger for eneloops and sanyo 2700 mah nimhs and was wondering what is an easy to use, possibly automatic charger to those. After spending an hour or so reading many posts about the different battery chargers choices , I am now more confused. I just need one that is simple and easy to use. The features I would like is 1. For AA and AAA....2. Automatic?? ....very user friendly. 3. Dual Voltage.. What is the difference between a refresh /recondition button and a discharge button? Are the two essentially the same? Thanks so much
