How to Tell When Your Hyundai Needs a New Car Battery

March 4th, 2022 by

Car batteries have a limited lifespan. It’s generally accepted that the effective life of a car battery is three to five years before it needs to be replaced. A flat battery will generally always seem to happen at the worst possible time. To prevent this, these are some tips from your Hyundai dealer that it’s time to get a new car battery.

Time for a New Car Battery From Your Hyundai Dealer

Slow Cranking

When you turn the key, your battery sends a strong electrical charge to the starter motor. This charge causes the starter to crank your engine. Your engine should then almost immediately turn over and you’ll hear the sound of a well-tuned engine. If that doesn’t happen, there’s a problem. The sound of an engine cranking more than once is a sign that your battery has a very low charge.

Normally your battery will start your car, and then your alternator will kick in. Your alternator will send a burst of electricity to the battery and begin recharging it. The low charge in your battery is caused by either a weak battery or a weak alternator. If your battery is old, it won’t be able to store a sufficient charge to easily start your car. A weak alternator could be the cause of the battery problem.

Battery Light Comes On

The battery-shaped light on your dash represents the electrical system, not just the battery. It will come on if sensors in your engine detect a problem. Sensors are attached to all the important components in your car to provide an early warning of any issue. These sensors are capable of detecting even small changes in the system. By getting a heads-up that there’s a problem, you’ll have time to get it repaired before it becomes a bigger problem.

When your battery is wearing out, its maximum recharge level shrinks, and the battery also becomes more resistant to charging. If the sensors detect that your battery is not charging at the rate it should, or it’s not supplying power at the level it should, the warning light will come on. The light can also come on if you have a bad alternator, as the alternator won’t be supplying enough power for all of your car’s components.

Bad Smells from the Engine

No one likes a bad smell, and a rotten egg smell from the engine is one of the worst. This smell is caused by gas escaping from a weakening battery. Your battery contains sulfuric acid, which will break down into other components in the battery. Some of the sulfuric acid vapor can escape the battery casing. This vapor will mix with other chemicals in the air and form hydrogen sulfide gas.

This gas will cause corrosion in your engine, particularly the battery, battery terminals, and battery cables. It’s causing the awful rotten egg smell. Your battery will need to be replaced.

Your battery will always show signs that it’s failing. If you’re worried about your battery, call us at Wayne Hyundai.
