The 5 Best Car Battery Warmers


Winters can be harsh on your vehicle. If you’re struggling to battle the cold winter weather, keep in mind that your car is too. It can become more difficult to start your vehicle during these cold months because the battery fluid can freeze over if you don’t take precautionary measures now.

What Is a Battery Warmer?

A battery warmer can keep your battery insulated and warm throughout the cold winter months. This will help to prevent the battery fluid from freezing over and will allow you to get your car started much more quickly in the morning. They are very easy to install and should make your life a lot easier. Typically, the warmer can be plugged into any standard outlet and can be easily wrapped around your car battery.

Having a jump starter kit can help to get you out of a bind when your car won’t start in the morning. However, having a battery warmer in place will help prevent a problem from occurring in the first place. Auto fluids can thicken at cold temperatures, but battery warmers will transmit the heat continuously, to ensure the liquids stay fluid, so you can start your vehicle right away.

Along with keeping your battery warm in cold climates, it can even help extend your battery’s life, deliver better fuel economy, reduce wear, and protect your engine from cold weather damage. To ensure you choose the correct battery warmer, simply measure the distance around your battery and select the warmer length closest to that distance.
