It might have happened to you, or someone you know. A car with a new, or relatively new battery suddenly not wanting to start anymore when seasons start turning.
This has nothing to do with the quality or the price of the component, rather, it’s simple chemistry.
Cold temperatures force batteries to work harder to get an engine started as the chemical reaction within the cells when the ignition is activated takes much longer when temperatures are low, according to the Automobile Association (AA).
Technologies such as lights, climate control, the radio, and seat warmers all take their toll on the battery, too, which can be overwhelming and cause the battery to fail when starting the engine on a freezing morning in June.
Important tips for battery care
In addition to regular maintenance, there are several ways to take extra care of your car’s battery to ensure longevity and reliability.
A good habit to develop is to make sure all the vehicle’s electronics are properly powered down when parking.
When arriving home, double-check that fixtures such as the headlights and cabin lights are turned off, the doors are fully closed, and accessories such as cigarette lighters and chargers are plugged out, else they could sip battery power overnight and leave you with nothing left in the morning.
Moreover, ensure that there are no loose cables or corrosion around the battery’s terminals as this hampers the module’s ability to successfully transfer energy to the engine.
If it is at all possible, also park the vehicle indoors to protect it from temperature fluctuations and the potential damages associated with it, especially at night.
However, don’t park the car for extended periods of time without driving it as batteries tend to lose charge if they’re not being used regularly, regardless of the season.
It’s ideal to fire it up at least once every three days to “keep the battery at its optimal level,” said the AA.
It is, however, worth noting that batteries only last around three years, so if your’s has been installed for longer, a malfunction could be a sign that the time has come to buy a new one.
