WARNING SYMPTOMS That Your Car Battery Is Dead

There’s nothing worse than getting stuck on the side of the road with a dead battery. It can be an expensive problem, too. So it’s important to know how to tell if you’re in need of a new one—and what signs to look out for.

It’s older than 3 to 5 years old.

Batteries aren’t designed to last forever, so if your battery is old, it’s time to replace it. In fact, most batteries are only meant to last three to five years before they need replacing again. If you have a car older than 10 years and haven’t replaced your battery in more than five years, then chances are good that you have a dead battery on your hands!

If this sounds like something that might be happening with yours (i.e., if you’ve had the same car for more than 10 years), make sure to get it looked at as soon as possible so we can get a replacement installed right away!



The battery is leaking or bulging.

A leaky battery is not just an annoyance; it’s a sign that there might be a serious problem with the car’s electrical system. If you see any signs of leakage from your car’s battery, take it to a mechanic immediately. A leaking or bulging battery indicates that there might be an internal short circuit in the car’s electrical system, which could lead to expensive repairs if not caught early enough. The best thing to do in this case is preventative maintenance by getting your vehicle serviced regularly and replacing worn out components before they cause issues like this one.



You can smell something rotten.

You can smell something rotten.

If you notice a strong, foul odor coming from your car’s engine bay, it could be that the battery has died. A dead battery will cause a leak of sulfuric acid that smells like rotten eggs and/or ammonia gas (which is why it’s called “sulfuric” acid). This substance can cause serious damage to your car if left unchecked for an extended period of time.

If you’re smelling an unpleasant odor from under the hood of your vehicle, proceed with caution! Be wary about turning on any electrical components until the problem has been identified and repaired by a professional mechanic at AutoZone .



The headlights are dim or flickering.

If your headlights are dim or flickering, it’s likely that the alternator is not charging the battery properly. The alternator works by converting mechanical energy into electrical energy and sending it to the battery. If there is a problem with this process, then you will likely see headlights dimming or flickering. A dirty air filter may also cause these problems as well as other electrical malfunctions such as poor starting performance and slow idling speed due to low voltage levels in the engine compartment caused by high parasitic loads on an undercharged system (such as from running accessories like power steering pumps).

When this occurs, it’s important that you take action immediately because if left unchecked for too long, your car could suffer serious damage from lack of proper voltage levels needed for starting up its various systems



The engine is slow to start.

If the engine is slow to start, the battery may be low on power. The battery might also be old and need to be replaced. Another possibility is that the alternator, starter motor or fuel pump are failing.



You’ve had a lot of electrical problems lately.

If you’ve been having a lot of electrical problems lately, it’s possible that your car’s battery is on its last leg. The following are some signs that may indicate a failing or dead battery:

  • Electrical issues
  • Instrument panel lights going out
  • Not being able to start the car

If you see any of these symptoms, it means it’s probably time for you to get a new battery. If your current one isn’t fully dead yet and has enough juice left in it (about 12 volts), then try jump-starting the vehicle using jumper cables connected to another working vehicle before buying a new one. Also be sure to have the charging system checked by an expert mechanic who can make sure there aren’t any other underlying issues causing poor performance from your car’s charging system—this could save money down the road!
