Description
Features:
- After connecting to the vehicle OBD, if successful, the red LED light will illuminate. The red light of some car models does not light up, and it does not affect the use. Observe the current level. If it is close to 4-5A, please immediately remove the battery replacement tool and charge the original car battery before proceeding.
- The car battery replacement memory is suitable for any 12V DC power supply. Simultaneously display voltage and current, with red indicating voltage and blue indicating current.
- Remove the tool from the OBD port. If both the digital tube and the red LED are on, it indicates successful replacement.
- Remove the fuse strips from the car fuse box in sequence and observe the current changes. If the current suddenly drops, it indicates a possibility of leakage in the fuse. By referring to the car circuit diagram and identifying the circuit or electrical equipment connected to the fuse, leaks can be ruled out.
- If the connection is successful, the digital tube will display the number (if the blue LED is on, it shows the current; if the blue LED is not on, it shows the voltage). If the positive and negative terminals of the battery are reversed, there is no need to worry, as the digital tube does not light up and there is no electricity passing through.
This product is only suitable for cars with 12V batteries, and the leakage current does not exceed 5A. If the digital display does not show when the battery is clamped, please re clamp the battery clamp.
If the original car battery is severely depleted, plugging in a battery replacement tool is equivalent to directly charging the original car battery, with a current of several amperes or even tens of amperes. Due to the 5A fuse of the tool, the fuse will burn out, which cannot achieve the goal of constantly replacing the battery. The original battery needs to be ignited, restarted, and fully charged before replacing the battery.
Connect the red clip to the positive pole and the black clip to the negative pole.
Before connecting to the OBD interface, the displayed voltage is correct and the current is incorrect because it is unloaded
Note:
During battery replacement, avoid using high current appliances on the vehicle that consume a lot of electricity, such as seat heating, headlights, air conditioning, etc., and turn them off. Do not open all car doors to avoid excessive current causing battery replacement failure.
