How to Detect Car Battery Leakage?

[VivienneAnn]

First, prepare a multimeter and select the correct range. Choose the DC current range, typically 10A for most cars. Connect the adjusted red probe of the multimeter to the car's grounding wire and the black probe to the negative terminal of the battery. After completing the above steps, wait for 30 seconds and read the multimeter's value. A dark current below 50mA is considered normal.
