12V 24-3Ah 200 100-2000 CCA Car Battery Tester Digital Analyzer Alternator Lighting for Car, Motorcycle, Truck, ATV, SUV, Boat

Car Battery Tester: Our car battery tester can test all 12V and 24V batteries, including standard flooded, flat AGM, spiral AGM, and gel batteries. Extremely wide testing range: 100-2000 CCA/3Ah-200Ah - Supports CCA, IEC, DIN, BCI, MCA, SAE, GB, JIS, and CA car battery standards - Compatible with cars, SUVs, pickups, boats, motorcycles, etc. Safe and accurate: The TE550+ can quickly and accurately test car batteries and dead batteries. Simply attach the tester clip to the battery, and with the battery tester connector properly connected to the car battery, it can begin working, whether the battery is inside or outside the car, or it can test dead batteries. Reverse connection protection: With the red wire connected to the positive terminal of the battery and the black wire connected to the negative terminal, the battery tester will function normally. Reversing the two wires will cause the battery tester to malfunction (reverse connection protection prevents damage to the internal circuitry, protecting the equipment and ensuring the long-term use of the car battery). Tips: 1. Turn off the engine before testing. 2. This device does not require a built-in battery. 3. When testing a dead battery, please charge it first. 4. The screen will not illuminate when the connection is reversed. The screen will illuminate in case of poor contact and display a warning: "Clip error." Battery health test: Utilizing the latest testing algorithm, it can quickly and accurately display various car battery data. Including internal resistance testing, voltage testing, waveform monitoring (real-time data display), state of health (SOH), state of charge (SOC), and CCA and AH value testing (CCA and AH values are automatically converted proportionally). Our car battery tester can test all 12V and 24V batteries, including standard flooded, AGM flat plate, spiral, and gel batteries. Extremely wide testing range: 100-2000 CCA/3Ah 200. Supports CCA, IEC, DIN, BCI, MCA, SAE, GB, JIS, and CA standards. Compatible with cars, SUVs, pickups, boats, motorcycles, etc.
