How to Keep a Car Battery From Dying in Cold Weather?

In the winter, a car battery is subject to severe conditions. When starting the engine, the energy needs are higher than in any other season during cold days. At this time more power is needed from the electrical system! The high power demand of the internal combustion engine in winter can cause problems for batteries if not regulated well.

How to prevent the death of a car battery in cold weather?

Here you can find some tips to help lengthen the life of your battery and prevent it from dying in cold weather.

Drive at a slower speed

If you drive fast, you need more power, which drains your battery faster than usual. Try keeping your speed to 55 miles per hour or even less if you can. It will help reduce the strain on the alternator and engine, which should help save the battery’s life.

Use your interior lights and other accessories less

The colder it is, the more energy your car uses to heat up. Try not to use your interior lights, interior mirror lights, or other accessories, and don’t leave them turned on. Instead, turn them off to help save energy and improve battery life. If you need to use these items, it only takes a second to flick the switch back on.

Park your car in a garage

If you park your car in a garage, it will be better for the battery. When the battery temperature is lower, the chemical reaction inside the cells is slower. In turn, this means that there will be less power available from the battery to propel your car.

Use a battery blanket

If you can’t park in the garage, invest in a battery blanket that will help keep the car battery warm and prevent your battery from dying. It is one of the best options if you need to park a car outside at night during winter.

Prevent Car Battery From Dying This Winter

Should I check my car battery before winter?

In general, it is good to do so at least once a month, but before winter, it is essential to make sure that the battery has enough power to start your vehicle.

What to check on your car battery?

  • Check for any leaks around the battery. If you notice a leak, it may be caused by a crack or break of plates inside the battery.
  • Check the battery’s voltage. If you have a digital multimeter at home, you can check if your car battery is still functional by measuring its voltage. For example, a standard 12V car battery should measure about 12.4 volts with a multimeter.
  • Check for sulfation. Sulfation occurs when sulfur residues are deposited on the lead plates inside the battery, causing the battery to lose its capacity to store electricity.
  • Check for corrosion. When checking your car’s battery for corrosion, look at the cables for any signs of rust or discoloration.
