Is your car battery dead?
Having trouble starting your vehicle? It might be a battery issue. Outside of running a free test at AutoZone, you can look out for the following symptoms of a bad battery:
Signs of a dead car battery
Your dashboard warning light
Your dashboard warning light comes on. Most cars today include an indicator that lights up when the battery reading isn’t good.
Engine cranks slow or not at all
Your engine cranks slowly or won’t start at all. The purpose of the battery is to crank the engine by providing a full dose of power to the starter. When the battery is low, it cannot deliver that power. This issue causes the crank to turn slowly, and you will hear that failure to crank properly when you engage the starter.
Your radio doesn’t turn on. Don’t mistake it for a minor inconvenience. When the ignition is in the ON position, the battery will run the radio, windshield wipers, and headlights, among other electronic devices. If these flicker or dim before starting, your battery charge is weak.
Swollen battery size
The battery is fat, or swollen. The manufacturer designs your battery to have a specific footprint, and if the battery swells in size, you should be able to see it. If you have a bloated battery, the alternator has a faulty voltage regulator and has over charged the battery. This over charging of the battery is caused by a buildup of hydrogen gases faster than the battery can dissipate. Damage to the battery has already been done and cannot be reversed.
Odd smell from your battery
If the battery smells – This is a warning sign that your battery is ready to fail, if it hasn’t already. Usually, a battery has no smell, by design. If you smell rotten eggs, this means that your battery has vented gas. It has also released sulfuric acid that could harm other parts of your engine. So this smell is potentially the costliest problem listed here if you aren’t proactive in fixing it. AutoZone recommends replacing the battery quickly.
Your battery is old
Your battery is old. The average life span of a car battery is typically between four to six years. At around the four-year mark, you should pay more attention to it. Have a technician check to see how much charge it has. AutoZone provides this service for free.
Check engine light flashes
The check engine light flashes or stays on constantly. Generally, this light identifies serious problems in your engine that will require costly maintenance. But you may get lucky and discover that it’s only your car battery that needs replacement. Visit your local AutoZone store for a free diagnosis.
