That's kind of what I was talking about. I've got a pretty decent Maha battery charger that can do conditioning, slow charging, and slow conditioning (which takes a couple of days if I remember correctly). However, I decided long ago that it simply wasn't worth my time to do that. I slow charge my batteries...and that's all I do to aid in their longevity. When they stop working well, I'll buy some more.
