Okay I can't beleive the size of giant pig of a battery MB puts in their cars! The thing is larger than the two marine batteries in my boat...

So I haver read a bunch of threads and it seems like there are two ways to go either Braille/Deka or Optima Yellow top.

Deka are cheaper but dont have auto post terminals, is there a way to change this?

Braille seems easy was going to go with the 21lb B3121. Is the aluminum mounting kit necesarry or is the $15 rubber one sufficient?

Optima love them for my off road vehicles and they take the AZ heat better than anything I have ever stuffed in a car. Still 40lbs but is it a safer option to not get stuck somewhere long term?

I ran a B2015 for months. I built a metal frame to hold it down out of some half inch think steel rods.

It turned it over fine and worked great.

Thanks for the response!

Figured I would get a little more feedback on this topic.

Odyssey and Kinetik batteries would be my choice....

Light weight and a lot of CCA.

You'll need the cranking amps our cars need a lot of juice.

I had B7548 for about a year; haven't fail me once yet. Don't think I would trust anything smaller.

Never Optima! They are the biggest POS batteries I have ever owned.
