It’s the quickest way to check voltage and see if your battery’s holding charge. A healthy 12V battery should sit around 12.6 volts or higher. Next, run a load test. Hook up a device you normally power and watch if the voltage drops fast. If it tanks quickly, your battery’s struggling..
To test a solar battery with a multimeter, first, you need to set the multimeter to the Direct Current Voltage (DCV) setting. Then, while the solar panel is in direct sunlight, connect the red lead to the positive terminal of the battery and the black lead to the negative terminal. [pdf]
