How to Test a Car Battery When It’s Not in Your Car
Method 1: Use a voltmeter
If you have a voltmeter, testing a car battery outside of your car is easy. First, make sure the battery is fully charged and has been resting for at least an hour. Then, connect the voltmeter’s red lead to the positive terminal of the battery and the black lead to the negative terminal. The voltage reading should be between 12.4 and 12.7 volts, indicating a healthy battery. If the reading is below 12.0 volts, the battery may be discharged and need to be recharged or replaced.
Method 2: Use a hydrometer
If you don’t have a voltmeter, you can use a hydrometer to test the specific gravity of the battery’s electrolyte solution. This will give you an idea of the battery’s state of charge. First, use a battery tester to verify that there is enough electrolyte in each cell. Then, use a hydrometer to measure the specific gravity of the electrolyte in each cell. If the readings are the same across all cells and are near 1.265, the battery is fully charged. If the readings are below 1.225, the battery may be discharged and need to be recharged or replaced.
- Important: Be sure to wear gloves and eye protection when handling a battery, as the electrolyte can be harmful.
- Note: Remember that testing a car battery when it’s not in your car is not a complete assessment of its health. Additional tests should be done when the battery is reinstalled in your car to ensure its proper functioning.
