Why car batteries die in Toledo winters

How cold Toledo gets

Toledo’s official weather station is at Toledo Express Airport. Its 1991–2020 climate normals from NOAA show why winter is hard on batteries here (NOAA monthly normals):

Those are averages. Plenty of nights fall well below them, and a car parked in a driveway or a street spot sits at the outside temperature all night.

What cold does to a car battery

A car battery makes electricity through a chemical reaction, and cold slows it down. At the same time, cold engine oil is thicker, so the starter has to work harder.

• NHTSA says that when the temperature drops, so does battery power, and gasoline and diesel engines need more battery power to start (NHTSA).
• AAA says that at 0°F a car battery loses about 60% of its strength, while the engine needs about twice as much current to start (AAA Hudson Valley).
• In January 2026, AAA described cold as dramatically reducing a battery’s ability to hold a charge and said battery problems are often the top reason members need roadside help during winter storms (AAA, The Auto Club Group).
• The U.S. Department of Energy notes that battery performance decreases in cold weather (fueleconomy.gov).

A battery that was getting by in October can come up short on the first cold January morning.

Warning signs before it quits

• Slow, labored cranking. AAA names this as the warning sign to watch for.
• Age. AAA recommends testing any battery more than 3 years old.
• Clicking with no crank, or dim dash and headlights, often point to a weak battery, though a loose cable or a starter problem can look similar.
• A battery or charging warning light on the dashboard.

NHTSA recommends having the battery and charging system checked before winter. It is easier to replace a weak battery on your own schedule than in a frozen driveway.

How to jump-start a car safely

If you have cables and a second car, follow AAA’s order (AAA Oregon/Idaho, AAA Club Alliance):

1. Park the working car close, on level ground, with the two cars not touching. Turn off both ignitions and all lights and accessories.
2. Clamp red to the positive (+) terminal of the dead battery.
3. Clamp the other red end to the positive (+) terminal of the good battery.
4. Clamp black to the negative (−) terminal of the good battery.
5. Clamp the last black end to bare, unpainted metal or the engine block of the dead car, away from the battery.
6. Start the working car, let it run a few minutes, then try the dead car.
7. Remove the cables in reverse order, and don’t let the clamps touch each other.

If you’d rather not handle cables in the cold, a jump-start service comes to you, at home or in a parking lot.

Jump start or tow?

For a no-start at home or at work, roadside assistance can often get the car running without a tow. If the car has to go to a shop, ask for a flatbed tow if it is all-wheel drive, four-wheel drive, hybrid or electric. Call (419) 329-4502 and your request goes to a local provider in Toledo or nearby, including Sylvania, Holland, Maumee and Oregon.

If your car dies on a highway shoulder rather than in a driveway, safety comes first: see what to do when your car breaks down on I-75 and emergency towing.

Electric cars and hybrids in the cold

Cold hurts electric vehicles in a different way: it cuts driving range.

• AAA says freezing temperatures can reduce EV range by up to 40% (AAA, January 2026).
• The Department of Energy cites a 2019 AAA study that found EV range can drop by about 41% in cold weather (fueleconomy.gov).
• NHTSA recommends keeping an electric vehicle plugged in at night in winter (NHTSA).

Gas cars feel it too. The Department of Energy says a conventional car’s city fuel economy is about 15% lower at 20°F than at 77°F, and up to 24% lower on short trips.

If an electric car does need a tow, carmakers such as Kia and Tesla say to move it with all four wheels off the ground. Our AWD and EV towing guide explains why.

Cold-weather habits that help

• Have the battery and charging system checked in the fall, especially if the battery is more than 3 years old.
• Keep jumper cables in the car. Both NHTSA’s and the National Weather Service’s winter kit lists include them.
• Keep the gas tank close to full in winter, as NHTSA recommends.
• If you have a garage, park in it on the coldest nights; a car inside starts warmer than one in the driveway.
• Plug in an electric car overnight.

Snow brings its own problems. If your car is stuck rather than dead, see stuck in snow or slid off the road near Toledo.
