This robust tool determines the state of a 12 Volt automotive battery. The load tester works by attaching the two strong clamps to the battery terminals. The LED immediately display shows either green (for good), amber (for weak) or red (for bad)
The button is used to place a 100 Amp load to the battery. Hold the button for 10 seconds to complete the load test. The LED display will then show the result after the test, either green, amber or red.
The tester also has a starter stress function to determine the battery voltage drop when the engine is started. The results are displayed on the large red display
The tester also works as a charging meter showing the charge voltage.
The tester is suitable for all 12 Volt batteries rated between 250 – 1000 Ah
