Enhancement to the recommended battery test equipment software, has removed the need to physically remove lead acid battery surface charge before completing a battery test.

The battery may be tested either on a bench or on the vehicle.

NOTE: Make sure the ignition is off and the vehicle is powered down with the modules entering 'sleep mode' before commencing the battery test.
