Thanks everyone for the replys. I have calibrated both batteries. Good or bad, that's already done.
I wasn't aware of the "trickle" issue. Sounds kinda nasty IMHO! LOL! But it's good to know mine isn't an isolated issue. I can live with the immediate percentage drop. Just wanted to see if anyone else was experiencing the same.
Thanks again. I'm going back to hit the "Thanks" button where appropriate.
