How to Check the Remaining Battery Level of a Car?

[LaJoy]

To check the remaining battery level of a car, you can follow these methods: 1. Check the battery's charge indicator. When the indicator shows green, it means the battery has sufficient charge; when it shows black, it indicates the battery is low on charge. 2. Measure the battery's static voltage. With the engine off, use a multimeter to measure the voltage between the positive and negative terminals, which should be between 12.5V and 12.8V. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. It is primarily made of lead and its oxides, with the electrolyte being a sulfuric acid solution.
