Corrosion on battery terminals can result in poor connections and reduce the efficiency of your car’s electrical system.

Over time, this corrosion can build up and prevent the battery from receiving the necessary power, leading to a shorter lifespan.

Avoiding these issues, can help to prolong the life of your car battery and avoid unnecessary replacements.

Why does my new car battery keep dying?

When you buy a new car battery, you expect it to function fully without issues of dying. There could be a few reasons behind this frustrating issue.

Let’s explore some potential causes when you deal with a dead battery after you’ve recently purchased a new car battery.

1). Defective new battery from manufacturing issues.

Sometimes, despite being brand new, car batteries can have defects due to manufacturing issues. These defects may prevent the battery from holding a charge properly or cause it to drain quickly.

If you suspect this is the case, consider reaching out to the manufacturer or the place of purchase for assistance.

2). Parasitic drain from electrical components in the vehicle.

Another reason your new car battery might be dying prematurely is due to parasitic drain. Parasitic drain refers to a situation where there is an electrical system issue that draws charge from the battery.

Faulty electrical components in your vehicle cause this parasitic drain. Even when the engine is turned off, certain devices can draw power from the battery and slowly drain it over time.

For example, radios, alarms, or even faulty wiring. It’s essential to identify and rectify any such electrical issues to prevent unnecessary battery drain.

3). Insufficient charging due to a faulty charging system.

A faulty charging system can also contribute to a shortened lifespan of your new car battery. When the engine is running, the alternator motor is responsible for recharging the car battery.

If your alternator isn’t functioning correctly your battery may not receive enough charge while driving. This can lead to frequent draining and ultimately reduce its overall life expectancy.

Furthermore, if there are problems with the voltage regulator or wiring connections the battery won’t recharge to maximum.

You can troubleshoot why your new car battery keeps dying and take appropriate steps towards resolving the issue effectively. But first you need an understanding of these potential culprits.
