Red, Yellow or Blue top Optima?

[340Cuda]

My understanding is that a blue top is the same as a yellow top (deep cycle) except they have the dual terminals. I run a red top for ignition and a yellow top for everything else.

When I bought my used Wells Cargo trailer, it came with an optima blue top battery. As mentioned, the blue top has 2 pairs of terminals, 2 regular terminals, and 2 smaller threaded studs. On my trailer the 2 large terminals went to the inside winch, and the smaller studs were for various 12 volt accessories, like radio, 12 volt lighting, tongue jack, alarm, etc. I replaced the Optima with a conventional deep cycle wet cell battery, because I could never get the Optima to take a full charge. Optima says that you need a special battery charger, I tried an alternate charging method, using a 2nd regular battery and booster cables, with a regular battery charger, but it never seemed as strong as I thought it should have been. The wet cell battery pulls the car into the trailer with the winch much stronger than the Optima ever did,

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.

We always use the Red tops, never failed on the SS/ car.

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.
