I'm satisfied... after trickle charging overnight, and a full 24 hours later, the battery is now floating at 13.46V, and I suspect it will come up just a tad more.

Rick you crack me up. Sorry, I meant "potentiometer". 1000 Ohm variable resistor at Radio Shack, in parallel with a 100 Ohm resistor. I wanted a 100 Ohm variable resistor, but the lowest they had was 1k so I cheated.

This got me to thinking about designing my own charger, that I could run off of my heavy 10A bulk charger that I use to get an initial recharge on my batteries. I'm not real happy with the technology that is available at the low end range. Even my 6A SunSaver by Morningstar allows the battery to over charge, which is nonsense. I think that with a cheap PIC or Arduino processor and power transistor, I could come up with a smart charger for about $15 in parts.

I should not gripe too much considering that I paid $4.99 for the Harbor Freight float charger. I couldn't buy the wall wart for that.
