Accuracy Plus Battery Tester

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.
Accurately tests the battery and starting/charging system in just 40 seconds.
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.
Load test technology is less sensitive to connections and side terminal batteries than conductance-type testers making in-vehicle testing more reliable with the Accuracy Plus.
Selectable battery ratings for cold cranking amps, cranking amps, and amp hours. Test range: 50 to 2,000 CCA, 1.0 to 14 volts.
Accuracy Plus will even accurately test the new acid flooded type batteries.
The no. 221-3156 offers wireless remote printing capabilities. No wires, no cables; just point and press a button and you can print out a complete report of the system you just tested.
2-line, 16-character display is easy to read even under difficult lighting conditions.
