Starting up your car alone draws heavily on your car battery’s power. So if you have other accessories such as the air-conditioner, lights and gadget charger already switched on when you start your engine, your car battery will have to work harder than usual. So make sure that they are switched off before starting your car. This will prolong your car battery life and minimize strain on other related components.

In fact, a good habit is to turn them off BEFORE you switch off your car engine so you don’t have to worry about forgetting to switch them off when you start you car.
