How Long Car Batteries Last

Making sure you take care of your car by scheduling normal maintenance is very important. Routine maintenance will not only help keep your car running smoothly, but it will also help prevent accidents. It is important to know the car battery life for the make and model of your car. I have learned the hard way that if you are not vigilant when it comes to taking care of your car, there can be some repercussions. Today’s blog post is about the typical life of a car battery and how to check and change your car battery on your own. If you are suffering from injuries due to an accident caused by a defective car battery, do not hesitate to contact an accident lawyer at Silverthorne Attorneys. Consultations are free!

Accident Lawyer | Car Battery Life

When it comes to your car battery life, it will greatly depend on how long it can hold a charge and if it is capable of being recharged. Once the battery cannot be recharged, it is dead and needs replacement.

There are a few things that can affect the life of your battery. From humidity, to temperature, and other environmental factors. Or even just good old wear-and-tear. Under perfect conditions, you can expect that your car battery life will last for about six years. The average being two to five years. Living in warmer climate will increase damage to a battery due to sulfation and water loss.

Extending Battery Life

The best way to ensure an extended battery life is to take good care of it. This means that you want to keep it fully charged. Meaning, do not leave lights on or accessories plugged in when you are not in the car or when it is not necessary to do so. When you go in for routine maintenance, make sure they check your battery life.

It is recommended in Southern California to change your battery every three to four years. This has a lot to do with how warm it gets throughout the year. As well as the fact that batteries can also age if they are simply sitting in your garage. Most, if not all batteries will have a stamp on them that tells you the month and year the battery was made. This is so you will have an idea of when it needs to be replaced. When in doubt, always check the owners manual.

Determining When to Change the Battery

Not all car batteries will fail like mine did in my last car. It simply died. Ignition wouldn’t turn over, etc. Here are some helpful tips on determining when to change the battery:

  • If you notice acid leaking or corrosion building up on the terminals;
    • Corrosion was a major sign for me on my last car. The battery hadn’t been changed in nearly seven years and corrosion kept building up – even when remove;
  • The warranty the battery comes with can also affect longevity;
    • Batteries usually come with 1-3 year warranties. A battery with a longer warranty usually means that it is build to last longer and has more power;
  • The best way to make sure your battery is in good shape is to test it regularly;
    • You also want to clean the outside terminals and connected wires on the battery;

Some mechanics recommend that you use a toothbrush with water and baking soda to clean around the terminals of your battery. Turn the car off and remove the negative and positive clamps. After you scrub the terminals, reconnect the clamps; starting with the positive terminal.

Checking Your Car Battery

There are ways that you can check your car battery life on your own. Here are some helpful tips:

Using a Voltmeter

  • Turn off the ignition;
  • Open the hood of your care;
  • Remove the battery’s positive terminal cover;
    • Check and clean if necessary;
  • Connect a voltmeter’s positive lead to the positive terminal on your battery;
    • The positive lead on the voltmeter will usually be red;
  • Attach the negative voltmeter lead to the negative battery terminal;
  • Check the voltmeter;
    • if the battery is in good condition, the voltage should be between 12.4 and 12.7 volts;
    • a reading lower than 12.4 bolts means that your battery needs to be charged;
    • if you come up with a reading of lower than 12.2 volts “trickle charge”” the battery. This us a slow charge – recheck afterwards;
    • if the reading is over 12.9 volts, there is excessive voltage. To fix this, you can turn on your high beams to remove any excessive voltage surface charge. Over voltage can be an indication that the alternator is overcharging the battery.

Using a Power Probe

You will follow the same steps as you would when using a voltmeter, just with a power probe. However, after you remove the battery terminals and connect the probe’s leads, you will then:

  • connect the tip of the probe to the positive battery terminal;
    • check the probe for voltage reading;
  • check the power probe reading;
    • if your battery is in good condition, the voltage will be between 12.4 and 12.7 volts;

The most important thing to remember is, that like humans, our cars need to be maintained and taken care of. Making sure you are vigilant about routine maintenance will ensure that you will be safer on the road.
