What is a good battery for SUB-ZERo temps?

When it gets REALLY cold what is a good battery?

Cold like minus 30.

THis is for a diesel.

I think you need a battery warmer.

Poor grammar is something up with which I shall not put.

A battery warmer will be your best and only option

I wonder if a dual battery setup would be the best option if you don't have access to ac power for a battery warmer. You would have to modify the tray to hold 2 batteries or move the batteries to the passenger compartment.
I'm also looking for a new battery and thinking that 900 cold cranking amps is what I need for my diesel. I also saw a lithium ion car battery used on one of those automotive tv shows, I wonder if those would hold up to the extreme cold you are talking up.

Lithium Ion batteries loose alot of power in extreme cold temps,much more then lead/acid batteries by far.You do not really want the batteries in the passenger cabin without the correct batteries used that have a vent port you can attach a hose to so you can route it outside the cabin.All batteries vent to some degree and it's some nasty stuff you don't want to breath in.

I'd try the Odyssey batteries for extreme cold,expensive but they are worth it.Totally skip over optima's,there junk now.

Yeah I wonder about battery venting too, though I seem to remember reading that the battery for the new wk2 is actually located under the passenger seat, so interior venting must be possible.

I ended up getting the Everstart Maxx H8 battery from Walmart for $117 as I could not wait or shop around. The H8 battery is 1000 CA and 900 CCA. It was the most powerful one I could find that fits. My OE battery was also an H8 rated at 800 CCA.

Those batteries,like Volvo's,have the battery vent that a hose attaches to and get's vented to the outside of the cabin.

interesting. I had bought a walmart battery for my car and it has lasted a long time. I was going to buy a canadian tire battery for my jeep, but maybe i will look at the walmart one too, though the CCA on the walmart website says 760?

The Website is WRONG! I thought so too and was going to get the 94R, then decided to look at the H8 which is same price but higher amps. Go check it out, maybe different provinces are getting different batteries from different suppliers??
