> **Quick Answer:** Try a jump start first if you have cables or a jump pack and the battery is less than four years old. Let the car run at least 20 minutes after a successful jump before turning it off again. If it won't take a charge, dies again within a day, or the battery is old, stop wasting time and call a tow. A dead battery in serious cold is often a battery that needs replacing, not just a jump.
## Should I Try to Jump Start a Dead Battery in Cold Weather or Just Call a Tow?
Jump start it first, but only if the conditions make sense. Cold weather doesn't just inconvenience a weak battery, it cuts a battery's available cranking power significantly. A battery that was borderline in October may be completely done by January. If the battery is under three or four years old and died because the car sat overnight in a hard freeze, a jump will probably work. If it's older, or if it died on a fully charged car that you just drove yesterday, the battery itself is likely failed and a jump is just delaying the tow call by an hour.
## What Do I Actually Do to Jump Start the Car in the Cold?
Connect red to dead, red to good, black to good, black to an unpainted metal ground on the dead car, not the dead battery terminal. This order matters because it keeps sparks away from battery gases. Let the good car run for two to three minutes before you try to crank. In temperatures below 20°F, wait five minutes. Cold-soaked batteries need more time to absorb even a surface charge before they'll crank.
If the engine turns over slowly but won't fire, that's a different problem: the oil is thick and the starter is working hard. Keep cranking attempts to five seconds at a time with 30-second breaks so you don't overheat the starter motor.
Once it starts, drive it. Don't idle in the parking lot. Get on a road where you can hold 2,000 RPM or higher so the alternator can push a real charge back into the battery. Short idle sessions after a cold-weather jump accomplish almost nothing. If the [battery warning light](https://towwiththeflow.com/battery-warning-light-on-while-driving-what-does-it-mean/) comes on during that drive, the alternator or the battery itself is not recovering properly and you need a shop, not another jump.
## How Do I Know If the Battery Is Too Dead to Jump Start?
If you get absolutely nothing when you turn the key, no click, no interior lights dimming, no dash lights, the battery may be so discharged that it can't accept a jump from a standard connection in under ten minutes. A battery that has dropped below about 10.5 volts in extreme cold is often in what's called a sulfated state and won't come back from a standard jump. This is common with batteries older than four years.
You'll also want to call a tow instead of jumping if:
- The battery jumped fine but died again within 24 hours
- You can see physical damage: a cracked case, a bloated side, visible corrosion eating into the terminal clamp
- The car needed a jump two or more times this same winter
- Temps are well below zero and you're sitting somewhere exposed and unsafe
That last point matters. If you're

on a highway shoulder in a winter storm, get safe first. [Breaking down on a highway at night in winter](https://towwiththeflow.com/broken-down-on-highway-at-night-safety-tips-what-to-do/) is a different problem than a dead battery in a parking lot. Call for help and stay in the car with hazards on.
## What Will It Cost If I Need a Tow Instead?
A local tow for a dead battery situation typically runs $75 to $125 for the first few miles, with per-mile rates of $3 to $7 beyond the base charge. If you have AAA or roadside coverage through your insurance, this may cost you nothing or just a small co-pay. [Check what your roadside coverage actually pays](https://towwiththeflow.com/how-much-does-roadside-assistance-cost-without-aaa/) before you assume you're covered, because some policies cap mileage or exclude battery service entirely.
If the tow gets you to a shop, expect $150 to $300 for a battery replacement depending on the vehicle. Cold cranking amps matter here: a truck or SUV in a cold climate needs a battery rated for 700 to 800 CCA or more. Don't let a shop put a budget battery in a vehicle that lives in a cold climate.

## Common Questions
**Q: Can extreme cold permanently damage a car battery?**
A: Yes. A fully discharged battery left in temperatures below 20°F can freeze internally, which destroys the lead plates. Even a battery that wasn't frozen can be permanently weakened after deep discharge in the cold. If it struggled all winter, test it before next season.
**Q: How long should I let my car run after a cold weather jump start?**
A: At least 20 to 30 minutes of actual driving, not idling. Idling barely charges the battery. You need road speed to get the alternator producing enough current to meaningfully recharge a depleted battery.
**Q: My car started after the jump but the battery light came on. What does that mean?**
A: It means the alternator is not charging the battery properly, or the battery is too far gone to hold a charge. Either way, do not turn the car off until you reach a shop. Once it's off, it likely won't start again.
**Q: Is a portable jump starter worth keeping in the car for winter?**
A: Yes, absolutely. A lithium jump pack rated at 1,000 peak amps or higher will start most passenger cars and trucks without needing another vehicle. They're compact, hold a charge for months, and pay for themselves the first time you're stranded alone.
**Q: Will my car insurance or roadside plan cover a jump start call?**
A: Most roadside assistance plans, including those from AAA, USAA, State Farm, and GEICO, cover jump starts. The key details to check are whether battery replacement is covered separately and whether there's a mileage limit on the tow if a jump doesn't work.
