Car Won't Start? Flat Battery Signs and When You Need a Jump Start

Few things are more frustrating than turning the key on a cold morning and getting nothing. In Ireland's damp winters, a flat battery is one of the most common reasons a car or van won't start. Here is how to tell, and what to do next.

Signs your battery is flat

• A rapid clicking sound when you turn the key or press start.
• Dashboard lights are dim, flicker or don't come on at all.
• The engine turns over very slowly, then stops.
• Central locking or the key fob stops working.
• The car sat unused for a week or more, or lights were left on.

Signs it is probably not the battery

• The dashboard lights are bright but the engine doesn't turn: possibly the starter motor.
• The engine turns over normally but won't fire: possibly fuel or ignition.
• The battery warning light comes on while driving: possibly the alternator.

When a jump start will work

If the battery is simply drained, a jump start from a professional booster pack usually gets the engine running within minutes. Once it starts, drive for at least 20 to 30 minutes so the alternator can recharge the battery.

Why use a professional jump start?

Modern cars are full of sensitive electronics. Connecting leads in the wrong order or to the wrong points can cause expensive damage. We use a dedicated booster pack, connect to the correct points and check the car is charging before we leave. See our jump start service.

When you need recovery instead

If the battery is old and won't hold a charge, or the problem is the starter or alternator, a jump start won't fix it. In that case we can load the vehicle and take it straight to your garage on the same callout, so you don't pay for two trips.

How to avoid a flat battery

• Drive the car at least once a week for 20 minutes or more.
• Turn off lights and accessories before locking up.
• Have the battery tested before winter if it is over four years old.
