What to do if your car battery dies

First of all, you’re going to want to know the ways of telling if your car battery is on its last legs. This way you can hopefully prevent it from completely dying or you can dismiss any chances of accidents being caused by it.

Here are some ways you can tell if your car battery could be coming to an end:

  1. Old age - your car battery can last over three years but we at Lindleys Autocentres recommend having its condition inspected on a yearly basis once it reaches this age

  2. Slow engine crank - If the cranking of the engine is sluggish and it takes longer to start than normal

  3. Engine light - sometimes your engine light appears when your battery is weak, but this isn’t always the case

  4. Battery leak - gunk around the point where the ‘+ and -’ connections are located may need to be removed

  5. Low battery fluid - if your fluid level is below the lead plates

  6. Car lights are dim compared to normal


The most obvious way of charging your car battery is through a car battery charger, however, if the car battery is completely dead, it’s likely that charging it won’t work at all. This means you could try a jump start, you’ll need jump leads and either another car or a power pack.

How to jump start a car battery

Please do not attempt this if you are unsure what you are doing:

  1. Take out your jumper cables (you can keep a set in the boot of your car)

  2. Make sure that both cars are stopped with the ignition off

  3. Attach one of the red clips to the positive part of the dead cars battery

  4. Repeat on the rescue car

  5. Attach one of the black clips to the negative part of the rescue car

  6. Attach the last black clip to an unpainted surface of the dead car away from the battery (you could use one of the metal struts that holds the boot open) this is an earthing point

  7. Start the working engine and leave it to run for a few minutes.

  8. Try to start the dead vehicle, if it won’t start leave it for a bit longer, if it starts do not turn the engine off for at least 15 minutes to allow the battery to recharge.

If jump starting doesn’t work you may have a more serious problem. Whilst your car battery is checked in its MOT there may be a problem at another time of the year. We provide a car service where we can replace and repair car batteries.
