Accurate measurements for each battery Thanks to advanced conductivity testing technology, this innovative product allows for accurate diagnostics of the condition of each type of battery with a voltage of 6 V, 12 V and 24 V. The tester provides accurate measurement results for AGM, GEL, SLA, EFB, WET and DRY lead-acid batteries. With a modern battery tester, you can quickly and accurately assess the condition of your battery and charging system by performing: Measurement of battery voltage and state of charge (%) , Battery life test to see if the battery needs to be replaced, Cranking current test to make sure the battery can start the engine, Alternator test to verify that the charging system is working properly, Internal resistance measurement Get a more accurate picture of the battery condition, Take screenshots of the results and save the data for better analysis. Battery diagnostics at the highest level The readable LCD display is one of the many advantages of this product. With the Qoltec battery tester, analyzing battery condition results is easier than ever. You can measure battery voltage, CCA cranking current, check battery condition and life and quickly identify a fault. The tester offers accurate measurement of two key battery condition parameters: SOC (State of Charge), which indicates the current energy level in the battery, and SOH (State of Health), which evaluates the battery consumption rate and helps determine its overall condition. Thanks to these results, the user can quickly assess whether the battery needs charging or whether its performance has dropped to a level that may affect the further operation of the vehicle or device.
