When the Car Battery Should be Replaced?

You may be wondering how do you know when the car battery should be replaced?  Inappropriately, a car battery may take only 3 to 5 years to become worn out and becomes unreliable around the 4-year mark.  Just like a mobile phone battery, it becomes less efficient with each charge.  

How do you know when the car battery should be replaced?  Battery manufacturers deliver advice on the lifespan of each battery produced.  Although, there are some things that drivers can do to help your battery last as long as possible:  

1. Limit short trips.  Batteries are not able to fully charge during short tours.  But driving regularly and for longer periods of time help maintain the charge in your battery.  
2. Tighten battery connections. A loose battery can vibrate, causing damage to the engine and electrical circuits.  
3. Turn off accessories & lights—shut the door.  Leaving the headlights on, the door open with a light on, or accessories plugged in for extended periods of time can drain a battery’s charge.  
4. Clean off terminals.  Keep the battery terminals free of corrosion.  A DIY tip:  Scrub with a mixture of baking soda and water, rinse and dry thoroughly. 
5. Test output voltage.  Test the output voltage of your battery regularly so you know if it is holding a strong charge.
6. Avoid using electronic accessories while idling.  Turn off accessories when you’re idling.  Turn the motor off if you will be sitting for more than 5 or 10 minutes. 
7. Regular tune-ups.  Regular tune-ups to change spark plugs, clean wires, etc. will help avoid overcapacity of the battery.  
8. Storing your car.  Keeping your car warm and dry will help your battery last longer. 

Remember:  Inspect the condition of your battery frequently so you are not left stranded in your driveway or a dark parking lot.
