Voltcheck Pro UCAN-Volt-II Car Battery Tester 12V 24V, 100 to 2000 CCA | Battery, Starter and Alternator Tester for Cranking and Charging Systems with QR Report | Cars, Trucks, SUVs, Boats

The YOUCANIC Voltcheck Pro UCAN-Volt-II tests the three parts that cause most no start problems: the battery, the starter, and the alternator. Clip it on, choose 12V Battery, 24V Battery, Starter, or Charging, and get State of Health, State of Charge, voltage, and CCA results in seconds. Rated for 100 to 2000 CCA and compatible with flooded, AGM flat plate, AGM spiral, GEL, and deep cycle batteries. Scan the on screen QR code to save or share your report with no app required. Built for DIYers and professional technicians who want an answer before they buy parts. Find out what is actually wrong before you replace anything.Slow cranking, dim lights, and repeat jump starts can come from four different places: a failing battery, a weak alternator, a struggling starter, or a circuit quietly draining current overnight. Replacing the battery only fixes one of them. This tester checks all four so you repair the real cause the first time.THE FOUR TESTSBattery health. Reads state of charge and charging capacity so you can tell a discharged battery from a worn out one.Alternator output. Shows charging system voltage so you know whether the battery is being refilled while you drive.Starter draw. Measures cranking voltage to reveal a starter pulling more current than it should.Parasitic draw. Finds the hidden current drain behind a battery that keeps going flat after the car sits.SPECIFICATIONSVoltage range: 1.5V to 30VCCA range: 100 to 2000Battery types: standard flooded, AGM, GEL, deep cycle, and hybrid auxiliaryLive data with on screen graphing of real time valuesBacklit LCD readable in a dark garage or under a hoodMulti language menusHeavy duty clamps that bite through terminal corrosionImpact resistant housingBUILT TO BE READ, NOT DECODEDResults appear as plain condition readings rather than raw numbers you have to interpret, so you can act on the result without a background in electrical diagnosis. Keep it in the trunk and test before a long drive, at the start of cold weather, or any time a battery is more than three years old.IN THE BOXBattery tester unitHeavy duty test clampsProtective carrying caseUser manual and quick start guide

• BATTERY, STARTER AND ALTERNATOR IN ONE TOOL: Run a battery test, a cranking (starter) test, and a charging (alternator) test from the same handheld unit. Find out whether a no start or slow crank comes from a weak battery, a tired starter, or a charging system that is not keeping up, before you spend money on parts you do not need.
• DEDICATED 12V AND 24V BATTERY MODES: Separate test modes for 12V batteries and 24V battery systems cover cars, SUVs, and light trucks as well as 24V heavy trucks, buses, and equipment. Rated for 100 to 2000 CCA with a 1.5V to 30V voltage range. Works with standard flooded, AGM flat plate, AGM spiral, GEL, and deep cycle batteries.
• CLEAR RESULTS IN SECONDS: Conductance testing reports battery State of Health (SOH), State of Charge (SOC), voltage, and measured CCA on a bright backlit color screen. One touch SOC and SOH buttons give you a quick health check without digging through menus, so you know right away whether to recharge, keep, or replace.
• QR CODE REPORT, NO APP NEEDED: The Cloud Print function puts a QR code on screen. Scan it with your phone to view, save, or share the full test report with a customer, a shop, or for a battery warranty claim. No app download, no Bluetooth pairing, no subscription.
• BUILT FOR THE GARAGE, BACKED BY MECHANICS: Heavy duty clamps, a 3 ft cable, and an impact resistant case with a protective rubber boot. Powered by the battery under test, so there are no internal batteries to replace. Includes a testing guide for reading results, plus US based product support from YOUCANIC, an automotive repair and diagnostics company in Maryland.
