Your battery is a necessary element essential to operating your vehicle. At Huffines CDJR Lewisville, Texas, we understand how essential your battery is. That's why our team of expert technicians test your battery as part of our free multi-point inspection on every visit.

How Does My Battery Work?

Your battery might look insignificant in size, but the power it provides is mighty indeed. Your battery converts chemical energy into electrical energy that provides electricity to power your starter which gets your engine running. After your engine is started your battery continues to provide the steady stream of electricity needed to keep your engine running, along with other various electrical systems.

The whole vehicle system is a cycle of energy conversion. It starts with the chemical energy stored in your battery that is released to the engine's starter. The starter converts this chemical energy into mechanical energy to power the engine. Once running, the engine powers your drive train to move your vehicle. It also operates the alternator which takes this mechanical energy and converts it back to chemical energy which is sent back to the battery for storage. The next time you start your vehicle your battery starts the cycle all over again.

Why Do Batteries Fail?

Statistics show that over half of all breakdowns are the result of a failed battery. There are several reasons a battery will fail and you might be surprised to hear that it isn't usually from factory defects. Instead, it can largely be laid at the feet of driving habits. This isn't manufacturers blaming the consumer, rather it's a simple explanation of natural processes that causes a battery to fail.

Sulfation


In America, the leading cause of battery failure is sulfation, a byproduct of the recharging process. The metal plates inside your battery can corrode over time because your battery is filled with acid that discharges sulfates during the electrochemical reaction of powering your vehicle. The sulfate crystallizes, but doesn't become a problem when your battery is run long enough to receive a proper charge. Shorter drive times are a contributing factor to this because your battery doesn't have enough time to fully recharge, which would drive the sulfate back into the acid and off of the metal plates.  When the discharge current is no longer sustainable within the plates, the battery will die. The positive material within the plate ages resulting in material flaking off. It occurs through the normal contraction and expansion process of the charging and discharging cycles. The result is a loss of plate capacity, as well as, a brown sludge that builds up in the bottom of the battery. This will eventually short the battery out.

Cold Temperatures


Cold weather is another reason car batteries fail. At 32 degrees your battery is 35% weaker and at zero degrees it is 60% weaker. A compromised battery will be far more likely to fail when it gets cold.

Human Error


The simplest reason your battery fails is human error. If you've ever forgotten to turn your headlights off you know what we're talking about. This will drain your battery of the necessary power to start your vehicle. It doesn't necessarily mean that the battery needs to be replaced. Usually, you can jump-start your car and it will return to normal function. Whenever your battery is drained you should bring it in for a checkup. Our friendly staff will perform a simple test that will tell you it's good or it needs to be replaced.

Bad Alternator


Your alternator might be causing your battery to fail, and this is more common than you might think. A bad alternator will not return the energy to the battery like it should, causing it to drain. Eventually, your battery is left for dead. Our technicians can tell you if it's your alternator or your battery with a simple test.

Symptoms of Battery Failure

Have you noticed a strain when you start your engine? Your lights may dim and the radio and other accessories might not work when you're trying to start your car. Once started these usually return to normal function because your engine's alternator is returning energy to your battery and supporting the system, but it could be a sign that your battery is running out of juice. If you see a green or blue crystalline-like substance growing from your battery terminal this is a sign of corrosion from sulfation. It's natural, but frequent short trips can encourage a build-up and prevent your battery from receiving a proper charge. You can clean this up and improve your battery's ability to recharge, but the damage may already be done.

Prepare for Anything

The best advice is to always be prepared for your battery to fail. This happens to nearly everyone so you may as well be ready for it. You can purchase a portable jump starter with its own battery and connections, or you can keep a set of jumper cables in your trunk. These are the go-to tools for temporarily fixing a dead battery and are pretty inexpensive. You simply connect your battery terminals to the terminals on another vehicle that is running, give it a few moments to let the power "jump" from the running car to yours, and voila, your car is running!

Remember, this may only be a temporary fix and one that won't last long if your battery is truly dead and won't hold a charge. Your alternator will continue to send power to your battery, but if it won't store the energy it is merely a connection to keep power flowing through your system. As soon as you shut down, your battery won't have the power to start you up again without another jump. You'll want to bring your car in for service if you need multiple jump starts.

The best advice is to have your battery checked by us at Huffines CJDR Lewisville. You can schedule service ahead or we can do it quickly at our Express Service Center and have you back on the road in no time.
