If the multimeter reads less than 12.6 volts, disconnect the battery and fully charge it using a battery charger. Then let it rest overnight. If it holds a charge when it's not connected to the car – something is draining the battery far faster than the computer memory and digital clock.
17 Σεπ 2024 · How To Check Car Battery With Voltmeter? To check your car battery, set your voltmeter to DC voltage, connect the red lead to the positive terminal and the black lead to the negative terminal, and read the measurement. What Voltage Indicates A Healthy Car Battery?
2 ημέρες πριν · Next, I touch the red probe to the positive terminal of the battery and the black probe to the negative terminal. A healthy, fully charged car battery should read around 12.6 volts or more. If the reading is below 12.4 volts, the battery might be partially discharged. A reading below 12.0 volts indicates a dead battery.
You can use a hydrometer-style battery tester to test the individual cells by testing the specific gravity of the acid in each cell, but even once you find a bad cell, you’re arriving at the same place you would by simply using your multimeter to do some simple voltage tests.
