6 Unmistakable Signs Your Car Battery is Failing

Your car battery is undoubtedly one of the most important parts of your vehicle. It’s responsible for providing power to all the electrical components, and it also helps start your car’s engine. 

So, if you think your battery might be failing, it’s important to know the signs. In this blog post, we will discuss unmistakable signs that your car battery is on its way out so that you can get it replaced before it dies.

Your Battery is Old (3 to 5 Years)

The average car battery lasts around 3 to 5 years. If your battery is older than this, likely, it won’t hold a charge like it used to. This can cause problems, including your car not starting when you turn the key.

If your battery is three years old, it’s a good idea to have it tested to see if it still holds a charge for long enough. You can take your car battery in for testing at most auto parts stores. If your battery is failing, you may need to replace it.

The Battery Smells Like Rotten Eggs

If your battery starts to smell like rotten eggs, it’s a sign that it’s failing. This smell is caused by sulfuric acid, a common component of car batteries. If you notice this smell, take your car in for testing right away.

The smell of rotten eggs can also signify that you have a leak in your battery. If the battery has a leak, replace it immediately.

Battery Terminals are Corroded

Corroded terminals are a sign that your battery is failing. Corrosion can cause problems with electrical connections, and it can also be dangerous. If you see corrosion on your terminals, let a dealership test it for you.

If you try to clean corrosion from a battery terminal, you could do more damage. Leave this job to a professional. If your battery is four years old and the terminals are corroded, it’s time for a new battery.

Car Doesn’t Start in Cold Weather.

If your car has trouble starting in cold weather, it could signify that your battery is weak. Batteries tend to lose power in colder temperatures, so you may need to give your car a little extra help in the winter. It’s best to get the battery charged or replaced to avoid getting stranded.

Dim Headlights.

If your headlights are dim, it could signify that your battery isn’t holding a charge well. This is often caused by terminal corrosion on the battery. If you’re not sure if this is the problem, have a mechanic take a look.

Engine Turnover is Slow.

If your engine turnover is slow, it could signify that the battery is weak. When you start the car, the starter will have to work harder than normal to get the engine going. If this happens, it’s best to replace or charge the battery as soon as possible.
