7 Signs Your Car Battery Is Going Bad

A car breakdown due to a dead battery is so preventable. With these tips, you can be aware of the signs of a failing battery and know exactly when it’s time for replacement so you won’t be caught stranded. 

  1. Slow Engine Crank
    If your engine takes longer than usual to start, or if it sounds sluggish when cranking, it could be a sign that the battery’s power is declining.

     

  2. Dashboard Warning Light
    Modern vehicles are equipped with a battery warning light on the dashboard. If you notice this light flickering on or staying on while you’re driving, it could indicate an issue with the battery or the alternator.

     

  3. Dim Lights
    If any lights are dim, if the radio is not working, or the wipers are slow, these might be signs that the battery is losing its ability to hold a charge. 

  4. Corroded or Loose Battery Terminals
    You should have your car’s battery terminals checked for corrosion on a yearly basis. A white, powdery substance around the battery terminals indicates corrosion, which can cause a weak connection and prevent your car from starting. Loose battery connections can also contribute to electrical issues.

     

  5. Frequent Jump-Starts
    If you need to jump-start your car often, your battery is likely on its last legs. If you notice that your car battery is low after sitting for a long weekend or a week at a time, chances are you need a new one.

     

  6. Old Battery
    Here is a rule to live by: change your battery every 4 years, every 5 years at an absolute maximum. Even if you’re not experiencing signs of power loss, it is a good idea to replace any car battery older than 4 years old to prevent an unexpected battery problem resulting in a breakdown. 

  7. Smell of Rotten Eggs
    If you smell an odor like rotten eggs around your battery, it could mean the battery is leaking acid or there’s an internal short circuit in the battery. This is a serious issue and can indicate an internal problem with the battery. You should get it checked immediately by a professional.

     

What to Do If Your Car Battery Is Going Bad

  1. Test Your Battery
    Auto repair shops can perform a quick test to determine the battery’s condition. This test will reveal whether your battery is holding a charge properly and whether it needs to be replaced. You can also confirm that there is not an auxiliary draw by testing the car’s electrical system at this time.

     

  2. Clean the Battery Terminals
    If corrosion is the issue, you can get your battery terminals cleaned to see if that will fix your low power problem.

     

  3. Replace the Battery
    If your battery is over 3 years old and showing signs of failure, it’s time for a replacement. A new battery will ensure that your car runs smoothly and prevent future breakdowns.

     

  4. Check Your Alternator
    Sometimes, battery issues are linked to the alternator, which charges the battery while you drive. If your battery repeatedly fails even after replacement, it could be a sign that your alternator isn’t working properly. Have it checked to ensure that your battery is being properly charged.

     

  5. Drive Regularly
    If your car sits idle for long periods, the battery can lose its charge. Try to drive your car regularly to help maintain the battery’s health.

Important: Always remember to wear full face protection when dealing with batteries as they can explode.
