How To Test Solar Battery With Multimeter. Any reading of voltage below 95 volts or if the battery holds a good record for a while and steadily drops or even when it falls instantly to 0 volts then it means there is a problem and the battery should be replaced due to its low capacity. Take a fluorescent tube and attach a wire to one end of it.
Touch the red probe to the positive terminal and the black probe to the negative terminal. It is mainly because the battery only creates DC power. 1 Begin with ensuring that your multimeter is set to DC voltage before learning how to check battery voltage using a multimeter.
Okay heres how you test the battery.
We will explain the process with a 9-volt battery for this guide. Check to ensure that you are measuring at a level that is higher than the volts the solar panel is rated for. A multimeter only has wire ends and when it comes in contact with the right terminal it shows the reading. The next step is to connect the black probe to the COM labelled port and the red probe to the VmA labelled port.
