It’s a well-known fact that automotive batteries don’t fare well in the cold. They can lose up to 60 per cent of their cranking power at just -18°C, and it can drop even further as temps get colder. You may have a battery that does just fine at home, but the same one might have trouble starting the car after sitting all the way through a cold weekend at the cottage. Fortunately, there is an easy and inexpensive solution: a battery blanket. Also called a battery heater, this electrically heated pad plugs into a household outlet to keep your battery warm. Installation is simple. Strap the blanket around your battery and route its power cord out the front of your vehicle. In most cases a warm, strong battery will start your car no problem, but in extreme cold, you may need to invest in a block heater as well. When you park for the weekend, just plug in the car and enjoy yourself. No more worrying about starting the car when you need it. Oh, but one last thing, don’t forget to unplug the car before you drive off!
