On really cold days turn your headlights on to "warm up" the battery before starting your engine.

THIS IS NOT TRUE!
- While there is no doubt that turning on your headlights will increase the current flow in a car battery, it also consumes valuable capacity that could be used to start the cold engine.
- Externally powered battery warmers or blankets and engine block heaters are highly recommended if the vehicle cannot be parked in a heated garage.
- AGM and Ni-Cad batteries will perform better than other types of wet lead-acid batteries in extremely cold temperatures.
