[63corvette]

I have a Davis roadster which uses a Guest Marine on board charger.
I also use 2 Optima red tops. They last 5 plus years for me in the race car and I just change them and move them to the pickup or my big mower for the last few years of their life. The one in the pickup lasted for almost 11 years before needing replacement.

I keep the race car plugged in full time at home and it works as a maintainer.
My Guest has 2 lugs that charge 5 amps each. I have the lugs tied together like the batteries. It is an on board small charger which makes it easy to just take a extension cord and plug it into a bulk head receiver on the car. Clean and simple without dragging around a charger. I have had this system since 2007 and it has worked well for me.
