Added Features beyond the Accuracy Plus:
1 Second battery quick test determines and displays CCA of the battery and lets you know if you need to conduct a full diagnostic battery test
Comprehensive battery test provides bad cell detection, CCA analysis, and battery diagnostics; improved testing system provides easier flow process, increased accuracy, and automatic temperature prompting.

Includes all standard Accuracy Plus features:
Accurately tests the battery and starting/charging system in just 40 seconds. Accuracy Plus is the most accurate battery load tester on the market, plus it's the most comprehensive starting and charging system tester in its price range!
Checks the battery, starter, voltage regulator, alternator and diodes.
The Accuracy Plus features interactive system diagnostics which applies a load to the battery and vehicle's electrical system.
With internal load capability the Accuracy Plus can monitor the charging system behavior under load and no-load conditions.
The Accuracy Plus relies on internal circuitry, not the vehicle's accessories or the technician, to load the electrical system during testing. That makes test results accurate and repeatable from test to test, vehicle to vehicle.
Accuracy Plus has an internal battery so it can test batteries down to a zero state of charge. It makes 'good/bad' diagnostic decisions on discharged batteries without charging them first.
Users can see a state-of-charge reading so they know exactly how long to charge the battery to bring it to a full state of charge.
Selectable battery ratings for cold cranking amps, cranking amps and amp hours. Test range: 50 to 2,000 CCA, 1.0 to 14 volts.
Bright 2 line, 16 character display is easily readable even under extreme lighting conditions.
