5 Warning Signs Of A Bad Car Battery You Can't Neglect

It’s always stressful when your car battery dies. Not only is it an inconvenience, but it can also be dangerous if you’re not prepared.

This post will discuss the warning signs of a bad car battery. If you can spot these signs early on, you can avoid being stranded on the side of the road.

1) You Need to Jump-Start Your Car Frequently

If your car battery is failing, you’ll need to jump-start it frequently. It means the battery isn’t providing enough power to the car, so you have to use another power source to get it running. If this is often happening, it’s time for a new battery.

2) The Car Doesn’t Start at All

If your car won’t start at all, that’s a pretty clear sign that the battery is failing. It’s weak and not capable of providing enough power to the vehicle to turn it on. This could be due to numerous issues, including a dead battery, a broken alternator, or corroded cables. If you’re unsure what the problem is, have a mechanic take a look.

3) Your Battery Case is Bulging

If you look at your battery case and see that it’s bulging, that’s another sign that the battery is failing. This could be because the battery is overcharged or there’s too much gas inside. Either way, this isn’t a good sign for your battery’s health, so you should replace it as soon as possible.

A bulging battery case can also be caused by a bad cell. This means that the positive and negative plates inside the battery are touching each other, causing them to become hot. The heat causes gas buildup in the cell, leading to the expansion of the battery’s casing.

If this happens, you’ll want to get your car checked out by a mechanic to see if the battery can be saved or if it needs to be replaced altogether.

4) Headlights are Dim

If your car’s headlights are looking noticeably dimmer than they used to, it could be another proof that the battery is beginning to fail. When a battery is healthy and fully charged, its voltage output will be around 12.60 volts.

However, as the battery loses power, that voltage output will start to drop. When it’s dropped to about 12.40 volts, the headlights will start to dim.

A failing car battery is much more likely to leave you stranded, so be sure to keep an eye out for any of these symptoms that your car might be trying to give you. If your vehicle demonstrates any of these symptoms, you should bring it to a mechanic as soon as possible.

5) Check Engine Light

A check engine light might come on for many reasons, but in this case, it means something has gone wrong with the battery or charging system. Whenever any warning lights appear on the dashboard, take your vehicle to a mechanic as soon as possible.
