Which Optima?

Blue tops are the ones you want, I was in a store not to long ago and I see they make a bigger one with more AH. I've been using 2 blue tops for 10.5 years with no problem, 9 of that was with a single stage charger until it died I now have a 3 stage. We just did a little trip over 5 weeks and only had electric hookups for 5 days and the batteries work just as good as they did 10 years ago.

OPTIMA is a very very very bad choice for a Motor home or trailer.> Very bad.

Here is why

First. of all the battery options save "Exotic" it is the most expensive
And second. they have only 60% of the capacity of a standard battery of the same size.

A far, far, far better choice is the LIFELINE AGM.. This is the cadillac of AGM batteries..(Optima is an AGM by the way) so you get over 50% more capacity (and weight) for the same footprint. and about the same price Just make sure it is a TRUE Deep cycle, not Marine rated.

Personally.. I prefer the lowest cost option (A pair of GC-2 Golf car Flooded wet cells) but. that is my preference.. But you'd like an AGM, epically a Lifeline, much better than that Optima.

The blue top have both a post and threaded terminal.

How many are you getting? You do have a three stage converter/charger yes?

Also search out capacity numbers. You just might be surprised how low those things are compared to other types of batteries.

I have 3 bluetops no problems

Looks like the blue top based on thier website, if anyone has experiance with them please chime in....

Optima since they moved their factory out of country has been having problems with quality, do a search and you'll see what I mean. A better choice would be a Lifeline AGM. And that is purely dependent upon what size/amp hour you want or will fit.
