What causes the Hyundai Elantra battery draining problem?

Hyundai Elantra drivers find their car battery draining overnight, during short periods, or while driving. To fix this nuisance of a battery draining problem, you have to understand what is causing it in the first place.

Does your battery drain while you are driving? You’ve got a faulty alternator. But if your

Hyundai

battery is dying overnight or repeatedly over short periods you didn’t see a battery light come on, then you are most likely dealing with a bad car battery that needs to be replaced.

Before you jump to conclusions and run off to replace your battery and alternator, the source of your Hyundai Elantra battery draining problem could be corroded battery cable posts or something is drawing power (think lights left on overnight!) when it shouldn’t be.

How to fix the Hyundai Elantra battery draining problem

The best way to fix the battery draining problem in your Hyundai Elantra is to have it properly diagnosed by a trusted mechanic. Take your car to a professional technician and leave it at the shop for a few days so they can observe the battery drain and find the root cause.

If the drain is caused by a bad battery, then the solution will be as easy as replacing the battery which can cost between $287 and $294 for parts and labor. However, there may be additional taxes and fees depending on the specific Hyundai Elantra you drive and where you live.

With nearly half the cost going towards labor, you can purchase a Hyundai Elantra car battery from the local auto parts store and replace it at home to save money.

Follow these steps to

replace your car battery

Check the owner’s manual for your car battery’s location

Identify the positive and negative posts and their respective cables

Loosen the bolts that secure terminals and cables to the battery post with a wrench

Disconnect the terminals and cables from the battery posts

Remove the retaining clamp holding the battery in place

Lift out to remove the old battery

Examine the cables to ensure their clean and corrosion free

Align the new battery to the positive and negative terminals

Insert the new battery and secure the retaining clamp

Apply anti-corrosion grease to the battery posts

Connect the positive terminal to the positive post and then connect the negative
