Welcome to D-90 Bill. Good to have an Optima rep on board. Sorry if this leads us off topic Wolf but I got 2 bluetops in my 110. Right now the previous owner has them running in parallel with no isolator unit. What do you think Bill?

1983 110 Rebuild

I've had two matching redtops in my 90 (wired together in parallel) since 1999 and they still work great. Just started the 90 for the first time in a few months this past weekend and she fired right up. With this batts now over 12 years old I'm temped to replace them but they are still working winching and all.

Years ago, when I did not know any better, I ran a Red and a Yellow top together in parallel, of different ages, without an issue for almost 4 years.

Now, I run 2 identical Yellow tops, purchased together they have been in the truck almost 5 years. Although, I do keep them on a tender now.

Running two identical yellow tops and have the battery tender leads permanently mounted to them so the battery tender goes on anytime it will sit. I got a wicked dual battery tender that minds both of them.

Mudsux, you should be fine as far as them being wired. However, we don't recommend using the wingnut terminals to power your winch. Our BlueTops (other than the 34M) are like the YellowTops in that they are dual purpose deep-cycling units.
I am not sure which BlueTop you have, but if they fit they are fine for the vehicle.

Guys, people mix and match batteries all the time, but as manufacturers, we recommend against it and don't warranty it.
I hope this helps,
