I'm running a blue top optima in my truck as the secondary battery, hooked up with a blue sea automatic charging relay.
I'd like to know more about this "spontaneous combustion" issue. I've been running mine for close to a year without a hiccup.
Keep in mind that LR max said that he had "heard" that. There may be someone who can shed more light on it. The Optima website does indicate that they are "Marine" use batterys and doesn't recommend them for the application as a auxillary battery. They recommend "yellow tops" for auxillary and HD use and "red" is for standard auto starting and continuous charge use. If you don't have to use your auxillary very much there shouldn't be much problem but what do I know. That's why I asked about batterys to start with.
