Feature:1. Adopting the conductivity method test principle, no need for high current discharge, and the battery has no heat and no damage.2. Three functions include battery test, start‑up system test, power generation charging system test, simple operation, easy to carry and store.3. The characteristics of the TPE rubber sheathed wire include extremely thin copper wire, silicone insulation, particularly soft, prevent breakage, and a length of approx. 1000mm/39.4in.4. Suitable for 12/24V automotive batteries, common liquid rich type (WET), maintenance free (MF), AGM, EFB start and stop, GEL, Marine, etc.5. Suitable for automotive start system and charging system test and CCA, DIN, IEC, EN, JIS Standard batteries and unknown standard batteries.How to Use:Connect the tester to the battery, the red clip to the positive electrode, and the black clip to the negative electrode. The analyzer will start automatically and display the battery voltage. If the analyzer cannot be opened, check that the clamp is connected to the wrong electrode.Specification:Item Type: Battery TesterMaterial: PC, ABS, silica gel and copper wireSize: Approx. 255 x 108 x 45mm/10.0 x 4.3 x 1.8inApplications: Suitable for 12/24V automotive batteries (Regular, AGM, GEL), automotive start system and charging system test.
