It’s always a good idea to make sure your battery is up to snuff but especially in the winter. Cold weather can rob your battery of its output. At 32F your battery may have only 50% of its summer strength. Firstly you should check the battery terminals to make sure the connections are tight and free of corrosion. Corroded terminals can stop the electrical connection. Secondly, have your service technician perform a load test, this will tell you the battery’s strength. This is also a good time to have your charging system checked. Take the time to check these things and it may save you from being stranded this winter.
