Dead battery: recognise the symptoms, prevent and fix

A dead battery is the number one cause of car trouble. Here's how to spot the signs in time, prevent problems and fix it quickly.

Dead battery: recognise the symptoms, prevent and fix

The car battery is one of the most underrated parts. On average a battery lasts 4 to 6 years, but cold, short trips and lots of electronics shorten that. With the right knowledge you avoid a frustrating morning with a car that won't start.

Symptoms of a weak battery

Watch for these signs that often precede a dead battery:

  • The engine starts slower than usual
  • Dashboard lights or headlights are dimmer
  • Electronics (radio, windows) respond slowly
  • The battery indicator lights up on the dashboard

How to prevent a dead battery?

A few simple habits significantly extend your battery's life:

  • Take a longer drive regularly so the battery charges well
  • Switch off all consumers before turning off the engine
  • Have the battery tested periodically on older cars
  • Drive a little more often in winter to keep the battery topped up

What to do with a dead battery?

Stranded with a dead battery? Two options: a jump-start with cables or a booster pack, or professional help. If the battery keeps draining fast, the alternator may be faulty or the battery due for replacement.
