4 FAQs about How to detect the current and voltage of the battery cabinet

How do you test a 12V battery?

For example, if you have a 12V battery, test it using the 20V setting. Using any settings beyond that would lead to a less accurate result. Most modern multimeters are autorange, meaning they set the proper range once you begin the test. If you're not sure what voltage setting to use, start at the highest one.

How do you test a battery?

Attach the red probe to the positive terminal. Attach the black probe to the negative terminal. Observe the needle movement. Ensure your eyes are directly in line with the needle to avoid parallax errors. Interpret the voltage by noting where the needle points on the scale. Check if the measured voltage matches the battery's rated voltage.

How do you use a multimeter if a battery is not ranging?

Turn the dial to the DC voltage mode. Select a range higher than the battery's voltage if the multimeter is not auto-ranging. Attach the red probe to the positive terminal. Attach the black probe to the negative terminal. Look at the digital display for the voltage reading. Ensure the reading is stable before recording the value.
