Best type 31 battery?
 

Ok before the optima cheerleaders come in, I'm going to throw in a curveball. What's the best type 31 battery for deep cycle only, with amp-hours being 95% of the buying factor.

Also, I noticed theres two different optima 31's, yet the specs are all the same?

Ah, figured it out... Post Vs. Stud... There's even a marine one...

All together now!

YAAAAAAY OPTIMA!

I just put in 4 Interstate ECL batteries for under $400 - the ECL stands for Extreme Cycle Life 8) . http://www.interstatebatteries.com/w.../tech_talk.htm

I have always used Interstate MHD batteries (Mega Heavy Duty) in fire trucks which is what I used to do for a living. They take some pretty good abuse.

I don't really care for Optimas, they are kind of expensive and I don't really care if the battery in my truck works when upside down anyway

Uh oh, looks like the interstates beat out the optimas in RC (reserve capacity). I wonder which battery is better for being cycled.

Here's a good FAQ:

Some AGM(Absorbent Glass Mat) battery specs:

Some "traditional" lead-acid battery specs:

Looks like the optimas are actually kind of weak for what I need, the odyssey batteries are superior.

Damn, cheapest I can find the Odyssey is $250, that's a lot of coin!

You get what you pay for when it comes to batteries.
