Best cold weather Battery

[Jhouserjr]

I am going to spend a month camping and skiing in the Colorado Rockies this winter. It is about time for me to replace the battery on my 2004 Astro. Would somebody from where the winters are bitterly cold give me a recommendation on which battery I should buy?

TIA,
John

I would look at AGM batteries, I've had good results with Sears Diehard Platinum AGM (Odyssey brand though no longer sold by Sears) and Pep Boys Bosch Platinum AGM (Exide Edge) that has a great warranty - 4 year free replacement & 3 year free roadside/jumpstart.

AGM are good in cold temperatures, lower internal resistance, low self discharge, less prone to sulfation and can charge faster though may require using charger with AGM specific charging profile.

I picked up the Bosch at Pep Boys with 30% online promo and $20 mail in rebate. That being said, having a battery with a good warranty and easily accessible locations to replace if necessary can be pretty important too.

If your are going to be parked for more than a couple days. A battery blanket might help also.

IMO, any new battery will be fine. There are other things that you can do as well to prep for harsh winters.

I spent three winters in Butte, MT where it could (and did) stay cold for months at a time at temps between 20F and -40F. Never had an issue with starting the engine with a generic (Sears) lead-acid battery.

I installed an engine heater and always carried an extension cord. I used the type that you just splice into one of the heater hoses. I forget the brand but the heater would also circulate the coolant. If it sat overnight, it was plugged in. I also used a straight 10w oil in the engine in case I couldn't find an electrical outlet.

Don't forget to pack a shovel and a bag of kitty litter.

No matter which battery you buy, look at the Cold Cranking Amps. The higher the CCA, the easier it will start in the cold and the longer the charge will last.

Personally, I go for the largest one that will fit, and I like the ones with side and top terminals. Keep it topped up with a solar/trickle charger when not being actively used. Other than that any decent battery will work just fine. Never had a problem with my cheap *** walmart batteries while living in, wow I hate to admit living there, but it was only for a few years, Maine.

Just to be clear, I'm not FROM Maine, never reproduced with anyone there, I was only on an extended visit ;)
