The car battery bubble when charging is a common issue that many car owners face, especially during the winter months. A car battery bubble, also known as a “bubble” or “blister,” is a small, rounded area of gas bubbles that forms on the surface of the battery. This bubble can cause the battery to malfunction, leading to a range of problems, from a slow start to a complete failure to hold a charge. In this article, we will explore the causes of the car battery bubble when charging, how to diagnose and treat the issue, and what you can do to prevent it from happening in the first place.
What Causes the Car Battery Bubble When Charging?
The car battery bubble when charging is usually caused by a combination of factors, including:
1. Overcharging
Overcharging is one of the most common causes of the car battery bubble when charging. When a battery is overcharged, the electrolyte inside the battery becomes overheated, causing the gases to expand and form bubbles on the surface of the battery. This can happen when the battery is charged too quickly or for too long.
2. Undercharging
Undercharging is another common cause of the car battery bubble when charging. When a battery is undercharged, the electrolyte inside the battery becomes too thin, causing the gases to expand and form bubbles on the surface of the battery. This can happen when the battery is not charged regularly or when the charging system is not functioning properly.
3. Corrosion
Corrosion is another common cause of the car battery bubble when charging. When corrosion occurs, the electrolyte inside the battery becomes contaminated with impurities, causing the gases to expand and form bubbles on the surface of the battery. This can happen when the battery is exposed to moisture, salt, or other contaminants.
4. Age
The age of the battery is also a factor in the development of the car battery bubble when charging. As batteries age, the electrolyte inside the battery breaks down, causing the gases to expand and form bubbles on the surface of the battery. This is a natural process that occurs over time, but it can be accelerated by other factors, such as overcharging or undercharging.
5. Manufacturing Defects
Manufacturing defects can also cause the car battery bubble when charging. Some batteries may have defects in the manufacturing process, such as imperfections in the electrolyte or the plates, which can cause the gases to expand and form bubbles on the surface of the battery.
How to Diagnose the Car Battery Bubble When Charging?
To diagnose the car battery bubble when charging, you will need to perform a series of tests and inspections. Here are some steps you can follow:
1. Visual Inspection
Start by performing a visual inspection of the battery. Look for any signs of corrosion, damage, or wear on the surface of the battery. Check the terminals and cables for any signs of corrosion or wear. (See Also: How to Get My Car Battery to Start? Quick Fixes)
2. Load Test
Perform a load test on the battery to determine its ability to hold a charge. Connect a load tester to the battery and apply a load to the battery. Check the voltage reading on the load tester to determine if the battery is able to hold a charge.
3. Voltage Test
Perform a voltage test on the battery to determine its ability to hold a charge. Connect a multimeter to the battery and take a reading of the voltage. Check the reading to determine if the battery is able to hold a charge.
4. Water Test
Perform a water test on the battery to determine if it is leaking or damaged. Check the battery for any signs of leakage or damage, such as corrosion or rust.
How to Treat the Car Battery Bubble When Charging?
To treat the car battery bubble when charging, you will need to perform a series of steps. Here are some steps you can follow:
1. Clean the Battery
Start by cleaning the battery to remove any dirt, grime, or corrosion that may be causing the problem. Use a wire brush and some baking soda to clean the terminals and cables.
2. Check the Electrolyte
Check the electrolyte inside the battery to determine if it is contaminated or damaged. If the electrolyte is contaminated, you may need to replace it. If the electrolyte is damaged, you may need to replace the battery.
3. Charge the Battery
Charge the battery to determine if it is able to hold a charge. Use a charger to charge the battery and check the voltage reading on the charger to determine if the battery is able to hold a charge.
4. Replace the Battery
If the battery is unable to hold a charge or is damaged beyond repair, you may need to replace it. Make sure to purchase a new battery that is compatible with your vehicle.
How to Prevent the Car Battery Bubble When Charging?

1. Maintain the Battery
Maintain the battery by cleaning it regularly and checking the electrolyte level. Make sure to check the battery regularly for any signs of damage or wear.
2. Avoid Overcharging
Avoid overcharging the battery by not leaving it connected to the charger for too long. Make sure to disconnect the charger when the battery is fully charged.
3. Avoid Undercharging
Avoid undercharging the battery by not driving the vehicle for extended periods of time. Make sure to drive the vehicle regularly to keep the battery charged.
4. Store the Battery Properly
Store the battery properly when not in use. Make sure to disconnect the battery and store it in a cool, dry place. Avoid storing the battery in direct sunlight or in an area where it may be exposed to moisture.
