The Motobatt MB-VM tool is a mini-tester for 12V batteries of motorcycles, scooters, ATV, cars on other vehicles. Practical and portable, just place the two tips on the battery terminals to be able to see the state of charge at a glance through the color of the LEDs. It is also able to test the charging system by means of two LEDs placed on the top which indicate correct charging between 13.8V and 14.7V (Green LED) or incorrect above 14.7V (Red LED).
