With this battery tester you can check the condition of your car battery by means of a resistance test. In contrast to the classic method where the battery is discharged by the applied resistive load and you read the result on the meter, this tester sends a number of impulse voltages through the battery cells and measures the alternating current through these cells.
Works on all 12V lead, AGM and gel batteries, regardless of size. The device uses a test signal pattern to test and monitor the battery cells. The battery is never discharged. Maintenance-free, no internal batteries required. Tests batteries in or outside the vehicle. Accurate results in milliseconds. Analyses the status of the battery. Large, easy-to-read LCD display. Test results based on the standards JIS, EN, DIN, SAE and IEC. Super compact (fits in the palm of your hand)
