Weak or Dead Car Battery? We're Here For You

Say you hear your starter struggling but it fails to produce results and start. In that case, you're probably dealing with a weak battery. A jumpstart usually does the trick in these circumstances. Once it starts, be sure to drive for at least 15 minutes to allow the alternator to recharge the battery. Later on, inspect the battery terminal to see if it needs to be tightened or cleaned.

1. Dead Starter

It could be that you have a malfunctioning starter if your car isn't starting. Dead starters are recognizable by the harsh grinding sound you'll hear when you try to start your car.

2. Dirty Spark Plug

Spark plugs ignite fuel in your vehicle's combustion chamber. Your car won't start if the spark plug is too dirty or old (though they have been known to last up to 100,000 miles).

3. Failing Alternator

It could be that your battery is in good working order, but if your alternator is failing, it will prevent you from being able to start your car.
