Hey, Why Is My Car Battery Leaking?

Hey, Why Is My Car Battery Leaking?
The battery is a chemical storage device that stores voltage for the vehicle's accessories. If for any reason, the battery is overused or underused, the chemicals in the battery can cause adverse effects on the internal components of the battery, causing it to wear or short out. When the battery is stressed, it can swell and cause the internal components to leak out. When a battery leaks, it can leak a clear liquid or develop corrosion that builds up around the battery and components around the battery.

Is Your Car's Battery Leaking?

The battery can leak by banging around if its hold-down rack is faulty.  However, the leak can also come from the terminals getting excess vibrations. Alternatively, if chemical reactions cause internal shorting, the battery can swell and crack.

Is your car battery leaking? Please don't ignore it! This is a clear warning that your vehicle's roadworthiness is compromised, which could lead to unsafe conditions. It's time to take control and understand what's causing the problem and what you can do about it.

Don't let the problem build up. It's always a good idea to seek the advice of an experienced technician to help you diagnose and fix the issue. By addressing the car battery leak early on, you can avoid costly repairs, keep your vehicle in top shape, and have peace of mind knowing you're safe on the road.

Let's Get To The Bottom Of It!

  • Q: Does the battery appear to be wet?

    Inside a car battery, some plates or cells hold acid and create energy for the car. A plastic housing separates the acid to keep everything safe and prevent short circuits. But if the battery gets damaged, like in an accident, it can cause the plastic housing to crack, and the acid can spill out. So even if the battery is securely tight, the housing can still crack and cause an internal acid leak. As a result, the battery might look wet or sweaty on the outside.

  • Q: Is the battery looking bulged?

    If your car battery is sealed, but the suspension or motor mounts are wearing out and making the battery bang around, there might be problems. The plates inside the battery can get damaged and short-circuit. This results in gases building up inside the battery, bulging it like a balloon. This can be dangerous, so consider assistance if your battery is swelling.

  • Q: Can the battery freely slide around the battery tray?

    The "battery hold down" is like a large metal belt that holds the battery on its tray. However, it wears quickly over time since it's so close to the battery and the acid inside. When this happens, the hold-down can break, making the battery loosely slide around the tray. This can be dangerous as the battery might bump into engine components or cause an electrical short by bumping the wrong spots.

  • Q: Is the "check engine" light on the dashboard?

    Your car's computer is smart enough to monitor the battery temperature. It uses a particular sensor that tells how hot or cold the battery is. This helps the computer ensure the battery charges at just the right speed. However, if the sensor goes on the fritz and sends the wrong information, it can cause trouble. For example, if the sensor always says the battery is too hot, the computer might charge it too much. And if it always says the battery is too cold, it might not charge it up enough. When this happens, the "check engine" light will warn that something's wrong.

Vehicle Health Inspection Proof

Explore the following typical inspection results that show a potential cause for the symptom and select the one you believe is similar to your vehicle's issue.

Alternator overcharging

The proof image is a voltmeter reading showing that the alternator was charging at a high voltage, confirming the need for replacement.

The customer dropped off their vehicle because they had to replace the headlight bulbs more often than usual. The last time they replaced a bulb, they noticed that the battery was hot to the touch. The customer also mentioned that the battery light was on the dashboard. However, they thought it was a false alarm since the headlights still shone.

During a test drive, the technician confirmed that the battery light was on the dashboard, and all other dashboard and accessory lights were bright.

The technician then inspected the battery and noted a surface charge in it. Therefore, the surface must be discharged before the battery can be tested appropriately. Still, all vehicle lights were working correctly.

Using a digital voltmeter, the technician tested the alternator's charging voltage and found it over 18 volts, which is too high. In this case, the test result means that the voltage regulator inside the alternator was not functioning correctly, causing the alternator to produce too much voltage.

Finally, the alternator must be replaced to ensure the vehicle's electrical system operates properly.
