Signs of a dead car battery

Your car battery powers your car's ignition system, radio, lights and more. It's important your battery is in mint condition to prevent you from getting stuck out on the road with a flat battery. Problems with your car battery can happen suddenly - however, there are a few key signs to look out for when checking if a car battery is dead.

Why do car batteries fail?

Some of the most common reasons why car batteries fail can include:

  • Extremes in temperature
  • Leaving on lights or the radio
  • Not using your car often enough
  • A car battery fault

In the event that your car battery fails, one of the quickest ways to get it going again is by jump-starting your car with a set of jump leads. You can find out how to jump start your car in out helpful guide.

Dashboard - battery warning symbol

Perhaps the clearest sign of your battery dying is a battery symbol on your dashboard. This could indicate a failing alternator, a loose starter terminal, or even damaged cabling.

If the light remains flashing while driving, there's likely a problem with your alternator belt - which is responsible for charging your battery while on the move. This shouldn't be overlooked - a faulty charging system could leave you stranded, so ensure to have this checked over by a professional as soon as possible.

What does the battery warning symbol look like?

The dashboard warning symbol will be a small battery icon with a plus and a negative sign to symbolise a battery. In most cars, the light will turn red to signify the issue.

Other signs your car battery may be dying

Difficulty starting the car

When your battery is going flat, an indication might be that your car needs a big surge of energy to start the engine. You will notice that the engine revs slower than usual and the car will take longer to start.

When turning the key, if you hear a clicking sound, this indicates that there is not enough power to start the engine at all. If this happens, it's important not to ignore this sign, as you will most likely need to replace your battery as soon as possible.

Low electrics

Your car's battery also powers the various electronics inside your car, such as windows, lights, heaters and more. If these aspects of your car are also playing up, this could also indicate issues with your battery. It's also good to note that you're more likely to notice these problems in the colder months.
