Hyundai is one of those brands that continuously manages to maintain a stellar reputation when it comes to reliability, but everyone knows that is not as black & white as that. For a single car to be actually reliable, it needs to be built well and based on an extensive R&D background, and trial and error testing cycles, to name a few.

Furthermore, it also needs a caring owner who is willing and able to do everything that needs to be done to keep the car in its optimum state. Even if all of that goes perfectly, there are still chances that your Hyundai is going to experience problems, especially with the battery which is why a “Hyundai battery problem “ is our article for the day!

Whether it’s a dead battery or issues with the charging system, these problems can cause inconvenience and frustration for drivers. Other issues include a corroded battery and loss of EV battery capacity over time which leads to a significantly reduced driving range.

So if you’re a Hyundai owner or considering purchasing one, keep reading to learn more about how to keep your battery running smoothly and efficiently. Granted, you might be one of those who never experiences any of these, but if that ever happens, you’ll be pleased you found this article!

Dead Battery

A dead battery is a common issue that many Hyundai owners face. Symptoms of a dead battery include dimming headlights, difficulty starting the car, and electronic systems malfunctioning. There are several possible causes of a dead battery, such as leaving the headlights, phantom drain, on, or not driving the car frequently enough to charge the battery.

One solution is to use a battery charger to recharge the battery. However, if the battery is old or has been drained too many times, it may need to be replaced. It is also important to ensure that the charging system of the car is working correctly to prevent future battery issues. Lastly, you should also check the battery for signs of a phantom drain at least 30 minutes after turning the car off and then find the culprit.

Charging System Problems

The charging system in your Hyundai is responsible for replenishing the battery’s power and providing electrical power to other components while the engine is running. If you are experiencing charging system problems, you may notice symptoms such as dimming or flickering lights, a weak or dead battery, or the battery warning light illuminated on the dashboard.

The most common causes of charging system problems in a Hyundai include a faulty alternator, a worn-out serpentine belt, a bad battery connection, or a faulty voltage regulator. These issues can lead to a weak or dead battery, leaving you stranded or unable to start your vehicle. Make sure to test out the alternator before replacing the battery as your battery might just be depleted, but not dead.

Corroded Battery

Corrosion is a common problem that affects car batteries, including those in Hyundai vehicles. Corrosion can cause a variety of issues with the battery, including difficulty starting the car or even a dead battery. One of the most noticeable symptoms of a corroded battery is a white, powdery substance around the battery terminals.

To prevent corrosion, it is important to keep the battery terminals clean and free of debris. Regularly inspecting the battery for signs of corrosion is also recommended. If corrosion is present, it can be removed using a mixture of baking soda and water or a commercial battery cleaner.

Loss of EV Battery Capacity

Loss of EV battery capacity is a common problem experienced by Hyundai EV owners. As with any battery, over time, the battery’s capacity to hold a charge diminishes. The loss of battery capacity can be caused by a variety of factors, including high temperature exposure, frequent fast charging, and battery age.

Symptoms of a loss of EV battery capacity include reduced range and the need for more frequent charging. To prevent or slow down the loss of battery capacity, Hyundai recommends avoiding exposing the EV to high temperatures for prolonged periods, charging the EV slowly when possible, and using the battery’s charge level between 20% and 80%.

How Good are Hyundai Batteries?

Hyundai batteries have a good reputation in the market for their quality and reliability. They offer a range of batteries for different types of vehicles, including traditional gas-powered cars and electric vehicles. Their batteries are known to be long-lasting and efficient, providing good performance and durability.

Hyundai has invested heavily in developing its battery technology, particularly for its electric and hybrid vehicles. Their latest EV batteries use advanced lithium-ion technology and have a higher energy density, providing greater range and power. These sure are not perfect, but nothing ever is.

How to Maintain a Battery?

Regularly clean the battery and terminals with a wire brush and baking soda solution, not just when you encounter loads of dirt on top of it. If you have a lead-acid battery, check the water level regularly and top it off with distilled water if necessary in order not to risk any problems.

Deep discharging is not good for a battery of any kind which is why you should try to avoid going under 20% of battery if not absolutely necessary. Use a multimeter to check the voltage of your battery regularly. If the voltage is consistently low, it may be time to replace the battery.
