What is used to check a tractor battery power?
A multimeter can measure a number of electrical properties and will be able to immediately tell you how much charge is left in your battery. These batteries are direct current (DC), so set the multimeter to read DC. Some models have 12V and 6V settings, so choose the appropriate setting.
Connect the multimeter leads to the battery’s terminals (red probe to the battery’s positive terminal and black probe to the battery’s negative terminal). Take the reading on the multimeter. If the multimeter reads somewhere around the value given on the battery’s label, the battery works fine.
