Jay Leno’s Garage Season 5 Episode 7

With no battery, your car simply is not functional.  Among the most inconvenient things in life is if your car battery suddenly dies unexpectedly!

But the good news is… there are several ways to know if your vehicle battery is on the verge of dying and needs to be replaced.   In this guide we will go over 7 signs your car battery is about to die and has to be replaced or repaired.

Before we begin talking these 7 critical signs, it is important to remember that if experiencing problems with your car battery, be certain to check the battery connections and cables first because sometimes a faulty connection can appear to be a bigger problem.

1) Slow Cranking – When turning the key, in case your car turns over for longer than normal or takes a while to”catch,” it often is because the battery charge is low.  While the starter can be the culprit, the majority of the time the battery is to blame.  If this is happening frequently, it’s a good sign your car battery is going bad and it may be time to replace your battery or recondition it.

2) Check Engine Light/Battery Warning Light – The check engine light is always a good indication of something off with your car or truck.  The battery power being weak will trip the check engine light.  This is only going to light up if there’s a problem with the battery.

3) Age – A car battery life span, in perfect conditions, is about five decades.  

4) Electrical Component Issues –  One sure indication your battery is starting to fade is if electric components are fighting to operate (such as lighting, windshield wipers, power locks, and windows).

6) Smell –  If you smell sulfur or rotten eggs under your hood, then this is often a symptom of leaking battery acid. This may damage other engine parts if not addressed quickly.  If you become aware of this, you may either bring your own battery into a store and have them look at it or you can use our reconditioning steps and do it yourself.

7) Multiple Jump starts Needed – if you are needing to jump your battery to get your vehicle started more than three times a week, it’s time to replace the battery or recondition it.  Excessive jumping can also damage other systems, so it’s ideal to have the battery replaced or fix the battery yourself.

If your car battery is showing any of these 7 signals, know that your battery needs to be replaced or repaired before your car no more runs.
