Default Re: Red, Yellow or Blue top Optima?

As a retired employee of Johnson Controls, that owns Optima I can tell you the facts. Yellow and blue are the same except for the terminals. You should use a Battery Tender charger or the one marketed by Optima, both are very good. The danger in using any other charger is over voltage. The batteries can take any current but the killer is a standard charger going over 15 volts. When I take a battery out of the race car in goes to trailer duty. Usually in the car 6 to 10 years.

I went with the Red tops, seemed to be the most logical choice. Thanks for all the input again.

I use the red in mine. No alternator. Charge between rounds. Never a problem.
