Hear boiling when charging battery golf cart

If you own a golf cart that runs on a battery, you might have noticed a boiling sound coming from it when you charge it. This could be alarming if you aren’t sure what’s causing it, but it’s actually a common occurrence among battery-powered golf carts.

The boiling sound you hear is essentially caused by the chemical reaction that occurs when the battery is being charged. As the battery charges, it produces hydrogen gas as a byproduct, and this gas can build up and escape through small vents in the battery. The rate at which the gas is produced can vary depending on several factors such as the age and condition of the battery, the temperature, and the charging voltage.

While it’s normal for a battery to produce some hydrogen gas when it’s being charged, excessive boiling and gas production can be a sign of overcharging. Overcharging a battery can lead to damage, decreased performance, and reduced battery life. It’s important to monitor your battery while it’s charging and ensure that it’s not being overcharged.

Why Your Golf Cart’s Battery Makes Boiling Noise While Charging



Many golf cart owners have experienced hearing a boiling noise coming from their battery when it’s being charged. This can be unsettling and worrying, especially for those who are not familiar with the technology behind the process. However, this is a common occurrence and does not necessarily mean that there is something wrong with your battery or golf cart.


The boiling noise is a result of the battery’s electrolyte solution reacting to the charging process. When a battery is being charged, the electrolyte solution heats up and can reach boiling point. This is a normal response to the chemical reaction that is taking place inside the battery. The boiling noise that you can hear is caused by the release of gas bubbles that are formed during this process.

It is worth noting that excessive gas formation can be caused by a number of factors including overcharging, a faulty charger or a damaged battery. In such cases, it is important to diagnose the issue and find a solution before it causes permanent damage to your battery or golf cart.


To prevent excessive gas formation, it is important to ensure that you are using a suitable charger and that you are not overcharging your battery. You should also regularly check your battery’s water levels and top it up if necessary. Additionally, it is advisable to have your battery checked by a professional regularly to ensure that it is in good working condition.

It is important to be aware of the normal sounds and behaviours of your golf cart’s battery so that you can identify any issues early on. If you are ever in doubt, it is always best to seek advice from a professional.



In conclusion, a boiling noise coming from your golf cart’s battery while charging is a normal occurrence. However, it is important to be aware of excessive gas formation and to take action if you suspect that there may be an issue with your battery. By following the preventative measures outlined above, you can ensure that your battery remains in good working condition for longer.

Understanding Battery Chemistry

Understanding Battery Chemistry


Battery chemistry is the scientific study of the chemical processes that occur inside batteries. It is important to understand battery chemistry because it helps us understand how batteries work, how they can be improved, and how to use them safely. Batteries are used in a wide range of applications from cell phones to electric vehicles, so understanding battery chemistry is crucial for advancing technology and ensuring safety.

Types of Batteries

There are many different types of batteries, each with their own unique chemistry. Some common types of batteries include alkaline, lead-acid, lithium-ion, and nickel-cadmium. Alkaline batteries are often used in everyday devices like flashlights and toys, while lead-acid batteries are used in larger applications like golf carts and cars. Lithium-ion batteries are commonly used in portable electronics like laptops and cell phones, while nickel-cadmium batteries are used in power tools and other high-performance applications.

Battery Chemistry

The chemistry of batteries is complex, but in general, batteries generate electrical energy through a chemical reaction. The reaction is usually between two materials – an electrode and an electrolyte. The electrode is usually made of a metal, while the electrolyte is usually a liquid or gel that contains charged particles called ions. When the electrode and electrolyte are combined, the ions flow from one to the other, creating a flow of electrical energy.

The type of chemical reaction that occurs will depend on the type of battery. For example, in a lead-acid battery, the reaction is between lead and lead dioxide electrodes and a solution of sulfuric acid. In a lithium-ion battery, the reaction is between a lithium compound and a carbon electrode, and a liquid or gel electrolyte. The exact composition of the materials used in the battery will affect its performance and safety.

Battery Safety

Battery safety is an important aspect of understanding battery chemistry. Batteries can be dangerous if they are not used or handled properly. Overcharging can cause the battery to overheat and potentially explode, while short-circuits can also lead to overheating and fires. It is important to use and store batteries correctly, and to dispose of them properly when they are no longer needed.

Overall, understanding battery chemistry is important for anyone who uses batteries, whether they are small button cells in a watch or large rechargeable batteries in an electric vehicle. By understanding the chemical processes that occur inside batteries, we can use them more effectively and safely, and continue to develop new technologies that rely on battery power.

Common Causes of Boiling Batteries

Common Causes of Boiling Batteries

1. Overcharging

One of the most common causes of boiling batteries is overcharging. When a battery is overcharged, it receives more current than its capacity to handle, causing it to heat up and boil. This usually happens when the battery charger is left connected for too long, or when the charger is not functioning properly. It is important to ensure that the charger is compatible with the battery and to follow the manufacturer’s instructions for charging time and voltage.

2. High Ambient Temperature

2. High Ambient Temperature

Another cause of boiling batteries is high ambient temperature. Batteries are sensitive to temperature changes, and excessive heat can cause the electrolyte to evaporate and boil. This is especially common in hot climates or when the batteries are exposed to direct sunlight. To prevent overheating, it is recommended to place the batteries in a shaded and well-ventilated area.

3. Battery Age or Damage

Boiling batteries may also be a sign of an aging or damaged battery. Over time, the plates inside the battery wear out, reducing its capacity and causing it to overheat. In addition, if the battery is physically damaged, such as having a cracked case, it may leak electrolyte and cause bubbling. It is important to check the battery regularly for signs of damage and replace it if necessary.

4. Incorrect Electrolyte Level

4. Incorrect Electrolyte Level

The electrolyte level inside the battery plays a critical role in its performance. If the level is too low, the plates may not be fully immersed in the electrolyte, causing them to overheat and boil. On the other hand, if the level is too high, the battery may vent excess gas, causing bubbling and boiling. It is important to check the electrolyte level regularly and add distilled water if necessary, following the manufacturer’s recommendations.

5. Poor Maintenance

5. Poor Maintenance

Finally, boiling batteries can also be a result of poor maintenance. If the battery terminals are corroded or dirty, it can increase the resistance and cause the battery to overheat. Similarly, if the battery is not charged regularly or is left in a discharged state, it can lead to sulfation, which can also cause boiling. To prevent these problems, it is important to clean the battery terminals regularly and to follow a regular maintenance schedule.

Understanding the common causes of boiling batteries can help prevent damage to your batteries and ensure optimal performance. If you suspect that your batteries are boiling, it is important to take prompt action to avoid any potential safety hazards.
