Newbie to Eneloops and charging in general. Bought the latest generation Panasonic/Eneloop charger BQ-CC17 which is supposed to be somewhat "smart". Can I re-charge Eneloops with just this charger with relative efficiency, or do I need a more sophisticated unit that can discharge and re-cycle to maximize run times and battery life. I read that Eneloops don't have much of a memory. If I stick with this unit, does it matter when I re-charge? Can I top-off, or should I discharge in my flashlights as much as possible? On a better unit, what charging currents are best for Eneloop AA's and AAA's? Any suggestions on a user friendly charger for an upgrade.
