How to Deal with Flat Car Batteries

Updated: Jul 14

Recognizing a Flat Battery


Common signs of a flat battery include:


  • The engine won’t turn over or turns very slowly.

  • Dashboard lights are dim or flickering.

  • You hear a clicking sound when you turn the key or push the start button.

  • There is no electrical power - this can affect the radio, windows, and lights.


Steps to Take If You Have a Flat Battery


1. Confirm It's the Battery


Before jumping to conclusions, check the battery first. If lights and electrics are working but the engine won’t start, the issue could be elsewhere, like the starter motor or ignition system.


2. Jump-Starting the Car


You can use jump leads and another vehicle or a portable jump starter. Here’s how to do it:


Jump Start Instructions (With Another Vehicle):


  1. Park the working car close by and turn off both engines.

  2. Connect the red jump lead to the positive (+) terminal of the flat battery.

  3. Connect the other end of the red lead to the positive terminal of the good battery.

  4. Connect the black lead to the negative (–) terminal of the good battery.

  5. Connect the other end of the black lead to an unpainted metal surface on the car with the flat battery (not the battery itself).

  6. Start the working car and wait a few minutes.

  7. Try starting the car with the flat battery.

  8. Once it starts, remove the leads in reverse order.


⚠️ Not comfortable with this? Don’t risk it. Give us a call, and we’ll advise you on what to do next.


3. Drive or Charge the Battery


After a jump start, keep the engine running for at least 20–30 minutes, or go for a drive to help the battery recharge. If the battery goes flat again quickly, it likely needs replacing. It’s best to take it into the garage to get it tested before it has a chance to let you down again.


Can a Flat Battery Be Repaired?


Sometimes, especially if the battery has simply been drained (for example, by leaving the lights on overnight), the battery will recharge and work fine. But if it’s old, faulty, or unable to hold a charge, it’s time for a replacement. Most car batteries last 3–5 years, depending on driving habits, weather, and maintenance.
