(ABC 6 News) -- You may have just finished thawing out from our last cold blast, but another is quickly approaching.
When battery voltage is low and temperatures push below freezing car batteries will freeze. Hundreds of car batteries died in the last cold spell with auto part stores and tow trucks working overtime.
We checked in with one of those stores who told us something you should not being doing with your car in the cold.
"When a car is at idle your alternator is not putting a whole lot into the battery so it's good for you because when you go out there it's going to be warm, but as far as your battery goes it will probably hurt more than help," Brady Crabtree with Advance Auto Parts said.
Instead of letting your car idle, it is better to drive it around for 5 to 10 minutes to allow the battery to charge.
