Why Does Golf Cart battery smell When Charging?

As you enter the parking lot, ready to hop on the golf cart and head to the field, a strange smell catches your attention. It’s not exactly pleasant, and you can’t help but wonder, “Why does the golf cart battery smell when charging?” Well, my friend, the answer lies in something quite simple: gases!

Yes, gases are the main reason behind that distinctive smell. The chemicals in the battery emit gasses during the charging process. When the golf cart battery is being charged, it produces these gases that waft through the air. Hydrogen sulfide gas is released in deep-cycle batteries while charging, which gives away a rotten egg-like smell.  

The smell can be unpleasant and worrying, but it can also indicate a more significant problem. In this article, we will explore the causes, risks, solutions, and prevention of golf cart batteries smelling during charging.

Why Does My New Golf Cart Battery Smell When Charging?

Most golf cart batteries use deep-cycle technology for efficient charging and discharging. Electrolyte solution in these batteries contains sulphuric acid and water that surround the lead plates. Once the charger is plugged in, a chemical reaction takes place that discharges hydrogen sulfide as a by-product. This gas is what gives a rotten-egg smell.

Is the Rotten-Egg Smell from a Battery Dangerous?

Though it is normal for batteries to emit this foul smell for the first 10 charges, anything longer than that should be taken seriously. 

When hydrogen sulfide reaches higher concentrations, it poses a more significant risk. In extreme cases, it can be immediately life-threatening, affecting the central nervous system and causing loss of consciousness, convulsions, and even respiratory failure. It’s crucial to recognize and address any concerning odor promptly.

Apart from the smell itself, there are a few key indicators to keep in mind. If you notice other signs like corrosion around the battery terminals, battery leakage, or the smell becoming increasingly overpowering, it’s time to take action.

The obvious sign will be an unpleasant smell coming out of the battery. The smell can be burning-like, rotten-egg-like, sulfur-like, and dusty-like. Other signs include hissing or bubbling sounds from the battery, a hot or warm battery, or a swollen or bloated battery. If you notice any of these signs, it is best to immediately turn off the charger and disconnect it from the battery.

Solutions to Avoid the Rotten-Egg Smell from Battery

Preventing golf cart batteries from making noise from rotten-egg smell during charging is crucial to ensure safety and prolong the battery’s lifespan. Here are some solutions to prevent golf cart batteries from smelling when charging:

Proper Ventilation

One of the easiest solutions is to ensure proper ventilation in the charging area. Good airflow can prevent the buildup of hydrogen gas and dissipate the golf cart batteries’ smell when charging. It is best to charge the battery in an open, well-ventilated area or install a vent fan in the charging station.

Regular Maintenance

Regular maintenance of the battery can also prevent it from smelling during

charging. Check the battery’s water levels regularly and refill it if necessary. Clean the battery terminals without a soda wire brush to remove any corrosion. Ensure that the battery is securely fastened and does not move during charging.

Using a Smart Charger

A smart charger can prevent overcharging and overheating of the battery. It can detect the battery’s voltage and adjust the charging rate accordingly, preventing it from overheating and emitting a strong odor.

Changing the Location of the Charging

If the battery smells during charging in a particular location, it may be best to charge it in a different location. Move the battery to a well-ventilated area or a place with less risk of igniting hydrogen gas.

Replacing the Battery

If the battery is damaged or too old, it may be best to replace it. A damaged battery can leak acid and emit a strong odor, which can be dangerous. An old battery may not hold a charge properly, leading to overcharging and overheating.

How to clean golf cart batteries that have already smelled

If the golf cart battery has already emitted a strong odor, it may be necessary to clean it thoroughly. Mix baking soda and water to neutralize the acid and remove corrosion from the terminals. Wear protective gear like gloves and goggles to avoid skin and eye irritation.

Why Do Golf Cart Batteries Smell Like Burning

The burning smell is common in batteries with faulty wiring or low water levels. This odor is much like burning plastic and indicates the urgency to refill the electrolytes or water. 

Regular battery inspections and proper maintenance can prevent this burning smell. If you are unsure about the battery wiring, call a professional. You can read our article on How to Wire Golf Cart Batteries in which we have shared wiring diagrams of different batteries. 

Conclusion

Golf cart batteries can emit a strong rotten-egg-like odor when charging, indicating a problem that can pose various risks. Overcharging, hydrogen gas buildup, and acid leakage are common causes of battery smells. To prevent battery smells, ensure proper maintenance, and good ventilation, use a smart charger, and replace the battery if necessary. In case of a strong odor, please turn off the charger and disconnect it from the battery immediately.
