How Do I Know if My Car Battery is Failing?

Warning Signs that the Battery in Your Vehicle Needs to Get Replaced

Like many things in this world, your car relies on electricity to function. Every vehicle utilizes a battery to supply energy to the engine and all electrical components inside your car. Without it, you won’t be able to drive your car at all, creating a big inconvenience for you if you must travel. So, how do you know if your car battery is failing? Here are a few of the most common warning signs that the battery in your vehicle needs to get replaced.

Engine Struggles to Start

One of the most obvious signs that your battery is failing is seeing how well your vehicle starts up. If your engine struggles to start, it’s likely that your battery won’t last for much longer. Shopping for a new one should be your priority as you won’t want to get stuck without transportation.

Corrosion on the Battery Terminals

Sometimes, the battery itself may still be good but the formation of corrosion can block the electric flow. Locate your battery under the hood. If you notice blue or white substances on the terminals, then you will need to rid these annoying particles with a cleaning. You can do this by first removing the negative clamp then the positive. Mix a tablespoon of baking soda with a cup of hot water and scrub the corrosion off with an old toothbrush. Once the terminals are clean, make sure everything is fully dry. Replace the clamps in the opposite order, starting with positive and ending with negative. Make sure the wrench you use never comes in contact with the other terminal when removing or replacing these clamps. If you aren’t comfortable doing this yourself, visit your local mechanic.

Dim Headlights and Problems Running Electrical Features

While not as obvious as an engine struggling to start up or corrosion on the battery terminals, it’s important to keep in mind how well electrical features run. For example, your headlights can dim as a result of not having enough electricity. Operating other electrical components like your radio or A/C may also struggle or not work at all.

How Long Do Car Batteries Last?

Many times, the car battery is failing just because it is old. On average, car batteries last roughly three years. If you haven’t replaced your battery recently, consider getting it tested before it becomes a big headache.
