The leagend AM2 is an OBD II battery monitor that plugs into the diagnostic port and keeps watch over the battery, with a built-in algorithm analysing state of charge and battery performance. It runs 12V/24V cranking tests to spot weak batteries and poor starting performance, and speaks up in English whenever battery level or cranking voltage drops too low. Built-in protection safeguards both the device and the vehicle's electrical system.
