Battery dies in extremely cold weather

Sounds like a parasitic battery drain or a charging system issue. Read this post on how to test

Battery dead in the morning Ricks Free Auto Repair Advice

Cold can definitely be the culprit. When you say the battery is "good", what are you basing that on ? And most people in the northern climates know that they need a really high cranking amp battery to be able to perform well on cold mornings. If you have a "cheap" battery, or got your car from a southern area, chances are that your battery has low cranking amps, and won't start your car in extreme cold (or extreme heat). See how many "cold cranking amps" or CCA your battery is rated at. It should be displayed on the top of the battery. If its low (300-500) that's probably your problem. If it's high, (800 & up) and your battery is actually reading 12 volts, your problem is likely somewhere else. Also the larger motor you have, the more CCA you need. Example, a small 4 cylinder escort may get by fine with a 500 CCA battery in cold weather, but a big V8 in a large truck may not turn over with a 500 CCA battery in below zero weather. Here is a good article to read. Car Battery Know How Cold Cranking Amps and Reserve Capacity

Oil can cause it or it could be the battery. Normally in cold weather you want a thicker viscosity like a 10w-40 and in the summer you want a thinner viscosity like a 5w-30
You can change the oil so its a little thicker if its that cold in your area. I don't know were you live but if your reaching the cold weather like in the 30s in the morning then changing the oil to a thicker oil could help.
Or a cheaper first try is to test that battery you have its cold cranking amps could be failing on you. So this is what you want to do;
If you got a battery jump starter you could try that in the cold morning and test it that way and see if it starts if it does then its the battery.

Hope that helps if it don't let me know.

You probably have a dead cell in the battery. Have it load tested at a auto parts place. Is usually fr

some of these vehicles go all bezerk when you try to jump start them and you have to have the ECM reset on them!

This really sounds like a problem with your battery. I know you said you checked it, but is it really putting out the appropriate voltage (12.66 volts) and CCAs? Even draining the battery once can damage it (especially in cold weather), and cold weather reduces the CCAs a battery can put out. A weak battery can cause those codes. When the vehicle hesitates to start, does that typically happen on colder mornings or after the car sat for longer periods of time? I would double-check your battery. If it's the original, it's near its end of life anyway.

Most likely cause is a weak battery or loose/corroded battery connection( This always happens in extreme cold weather). Check your connection at battery for corrosion. If the connections are clean and tight then possibly its the battery. Try jumping vehicle with cables if you are familiar with how to do that. If not do you have roadside assitance through your car insurance?
Hope this helps

you can jump it with a running car, then take it to somewhere like Autozone which will check the charging system and battery to see if there is a problem. Also sometimes you need to remove the battery cables and clean both them and the battery terminals.

WELL UR BATTERY HAS DEAD CELLS Y ITS DYING AND WHEN UR BELOW 0 A BLOCK OR OIL HEATER I A GOOD IDEA TO HAVE.A DIPSTICK OIL HEATER CAN BE BOUGHT AT AUTO STORE .

Have you had the battery checked..Cold weather is the worst enemy on a battery. They work fine in summer but cold will get em.
