If you've been in MN more than a summer, then you KNOW about the winter cold, and should know how to make sure your car runs.
1. You buy an oversized (capacity) battery. The biggest one that will fit in the vehicle. If it costs $200, so what. BUY it!!
2. You install an engine block heater.
3. You have a quality battery charger.
4. You park in a structure overnight, if possible.
5. And of course, keep a QUALITY set of jumper cables (heavy copper wire, not aluminum) IN your vehicle at ALL times, and KNOW how to connect them. No negative cable (the last of the 4 connections) to the frame or bumper or body. It needs to be an engine bracket, away from your battery area.
6. There are battery heaters, which can keep the capacity of the battery high in the extreme cold weather.
The freezing temperature of a fully charged lead-acid battery is around -75°F.
The freezing temperature of a mostly discharged lead-acid battery is around 32°F.
Source(s): The battery capacity (ability to make energy) drops as the temperature drops. At -30°F, the battery capacity is less than 40% of the capacity at 68°F. https://www.wisebread.com/the-5-best-car-battery-w... https://goo.gl/images/hMDs3z http://www.polarwire.com/asfb-boostercables.html https://store.polarwire.com/jumper-booster-cables/...

REMOVE the BATTERY and have it TESTED! If it is NOT a FACTORY unit and IS an AUTO ZONE type battery, plan on TOSSING IT OUT! Get a good USED BATTERY fromn a WRECK at the JUNK YARD with a KNOWN NAME BRAND maker! AC DELCO INTERSTATE< AUTOLITE! A REAL eEuropean battery will last for 27 years and MORE! IT is FOOLISH not to use the BEST quality MTCHING synthetic oil in ANY car made after 1990 as they were MADE to use them! A GOOD SYNTHETIC CHANGE is good for MORE than ONE FULL YEAR and protects to SUB zero temperatures and makes STARTING easioer! ENGINES using VALVOLINE are DOOMEd to wear out! PENNZOIL PLATINUM gives a 500,000 Miles WARRANTY with it, TOO! AMSOIlis ALSO excellent! LEARN how to READ your oil! It is VERY EASY! INTERSTATE makes GREAT batteries with VERY LONG warrantie periods! GOOD LUCK!!

Charge up the battery and use starting fluid to entice it into life. cover the car with blankets overnight.

Wait for the warmer weather. And it might be time to invest in a block heater and trickle charger.

You’re trying to start it right at the edge of the limits it is designed to cope with: probably even a bit beyond them for most cars.
Just wait until the temperatures get a bit higher: if the engine turns over weakly then recharge the battery as cold kills them, and an extremely cold engine with cold-thickened lubricants pits a huge load on the battery.
If you can't wait then use a sump heater: you can make one using a metal lidded tin which is shallow enough to fit under the sump (oil pain). Punch some holes in the sides of the tin and then put one or two tea-light candles inside. Light them and replace the lid, and slide the heater under the oil pan. Leave it overnight, and in the morning the oil in the sump (oil pan) will be warmed up enough to make it far easier to start.

I prefer not to start my own vehicle unless it's an emergency any temperature lower then -15 degrees Fahrenheit.
