Brent,

A bad cell in the battery could cause that as it will lose capacity. If you want to mess with checking your charger, try it on another battery that you know is good and see if it gives you the same type readings. I have had a red top Ultima in my car since 96 and have never had a problem, but I keep a cheap battery tender on all of my batteries when they are sitting for long periods.
