The ‘Magic’ Tip That Could Keep Your Car Battery Going for Longer

Most car batteries deteriorate gradually rather than failing without warning. Repeated short journeys, long periods of inactivity, temperature extremes and modern electrical systems can leave the battery consistently undercharged until the engine suddenly refuses to start.

The closest thing to a “magic” solution is simple: keep the battery properly charged, ideally with a compatible smart charger when the car is used infrequently. This advice applies to conventional 12-volt starter batteries, not the large traction batteries powering electric vehicles.
