If your car will not start and you hear a slow crank or just a clicking sound, a flat car battery is the most likely cause.
Knowing how to jump start a car safely can get you moving again without waiting for recovery.
However, modern vehicles contain sensitive electronics. Incorrect use of jump leads or a battery booster pack can cause damage or even injury.
If at any point you feel unsure, it is always safer to contact a breakdown professional.
How Do You Know If The Battery Is Flat?
Common signs of a flat battery include:
- The engine turns over slowly or not at all
- A rapid clicking noise when turning the key
- Dashboard warning lights flickering
- Electrical systems working weakly or not at all
- The central locking failing
If the engine does not crank and the lights remain bright, the issue may be the starter motor or another electrical fault rather than the battery.
Before attempting a jump start, check the battery for visible damage. Do not proceed if the battery casing is cracked, leaking, heavily corroded or smells strongly of sulphur.
