Im looking for the best battery for cold weather.. Not used in the summer.. just 100% winter.. Stand alone battery.. no block heaters.. no battery blankets.. Used in a Heated Container.. Atleast 1000CCA.

Something that will not freeze.. as it could be as cold as -40F

These cans ship from Toronto to Edmonton, Calgary, Vancouver, Winnipeg.. lots of cold places!

What are my choices..

I was thinking the biggest Yellow Top i can fit [coffee]

I don't know what the best battery is, but i've heard of battery blankets that are supposed to help out in cold weather. Maybe that is a possibility too.

Caterpillar has some machines that are spec'd out with an "Arctic Package".. I wonder if they have different batteries?
What about OPTMIA gelcell batteries?.. I know they are durable, not sure about cold weather though. Not much cold weather in Texas.

exide orbital gel batteries- just as good as optima's but alittle bit cheaper.

any spiral cell battery will throw out more cca's than standard lead acid batteries, but for extreme cold weather power and a long reserve then AGM (absorbed glass mat) batteries will take a severe beating in the cold weather and rough terrain. As long as you stay with a spiral cell battery or am AGM then you will be fine.

I run the Odyssey PC2150S Batterys they take a beating and keep on giving. they are pricy but well worth it. got mine from batterymart.com they have full spec there. i will take them over optimas any day. and yes i have run optima blue tops before. odyessey batterys were /are built for aircraft and millitary use.

exide orbital or optima. exides seem to recover from low discharge better.

I went with your first idea...

go with the biggest yellow-tops they make ('cept mine are blue!) [guitar]

-40C? Good Grief!!! If Optima etc AGM's won't survive, maybe you guys should consider some Ni-Cd starting cells(NIFE brand etc.) for that critical application at such a low temp.
Won't freeze even when completely dead like a Lead-Acid batts will.
They don't wimp out on starting current even at extremely low temps.
Chargers must be taylored for wetcell NiCd battery voltage characteristics.
EXCELLENT starting batteries, but a teensy bit pricey though:o

Check out the Commercial Optima Group 31's....

Not cheap...$275 each or so (Edmonton price)....

Odyssey also makes some very nice HD batteries:

Battery blankets do work ok...but make sure you get ones that are the lowest wattage rating...some tend to me way too hot, and only use them when its minus 25 or colder.
