How to Check Car Battery Power Level?

[DylanLynn]

Start the engine and let it run continuously for 5 to 10 seconds. Simultaneously observe the reading on the voltmeter. For a 12V battery, if the voltage is at or above 9.6V, it indicates the battery is in good condition. If it's below this value, it means the battery has insufficient charge.

I usually enjoy working on my car myself, and for a simple battery check, I use a multimeter. First, park the car on level ground, turn off the engine, and wait for five minutes. Then, open the hood and locate the battery terminals (red is positive, black is negative). Set the multimeter to the DC voltage 20V range, touch the red probe to the positive terminal, and the black probe to the negative terminal or a metal part of the car body. A normal reading should be above 12.6 volts for a full charge, between 12.4 and 12.6 volts means the battery is usable but charging is recommended, and below 12.4 volts may indicate insufficient charge, requiring immediate attention. Performing this check two or three times regularly can prevent sudden battery failure. Especially in winter or when the car is not used for long periods, regular maintenance is essential to avoid starting difficulties and travel disruptions. This also allows you to monitor battery aging and extend its lifespan.
