7 Signs Your Car Battery Is About To Die and Should Be Replaced (or reconditioned)

Without a battery, your car simply isn’t functional.  One of the most inconvenient things in life is when your car battery suddenly dies unexpectedly!

But the great news is… there are a number of ways to know if your car battery is on the verge of dying and has to be replaced.   In this guide we’ll go over 7 signs your car battery is about to die and has to be replaced or reconditioned.

Before we get started talking these 7 critical signs, it’s important to note that when experiencing problems with your car battery, be certain to check the battery connections and cables first because occasionally a faulty connection can appear to be a bigger problem.

1) Slow Cranking – When turning the key, if your car turns over for longer than normal or takes a while to”grab,” it often is because the battery charge is low.  While the starter can be the culprit, most of the time the battery is to blame.  If this is happening regularly, it is a fantastic 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.  If your check engine light is on, be sure to check the battery power level.   This will only light up if there is a problem with the battery.

3) Age – A car battery lifespan, in ideal conditions, is about five decades.  

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

5) Swollen Battery Case – If you look under the hood and your battery case looks swollen, bloated, or malformed; it is a indication that temperature has influenced the chemical components of the battery, shortening the lifespan.

This can damage other engine components if not addressed immediately.  If you become aware of this, you can 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 car started more than three times a week, it is time to replace the battery or recondition it.  Excessive jumping can also damage other systems, so it’s ideal to get the battery replaced or fix the battery yourself.

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