Your car battery is calling for help – Car Battery Tester
Have you ever experienced difficulty in starting the engine when you are ready to start your car? This is your car battery calling you for help, your car battery is about to run out of life and needs to be replaced in time to protect the normal functioning of our car, otherwise it will be in danger. This article will give you detailed information on how to check your car battery with a car battery tester.
1.There are several possible reasons why a car battery suddenly dies:
- Parking the car for a long time can cause the battery to fail. If the car remains parked too long, the battery may lose its charge due to irregular discharge, making it unusable.
- The battery reaches the end of its service life. Car batteries typically last 3-5 years, so drivers who use their cars daily should check and replace their batteries approximately every 4 years.
- Insufficient electrolyte or battery leakage. If there is not enough electrolyte in the battery or there is a leak, the performance of the battery will be affected and may lead to battery failure.
- A blown fuse causes the battery to lose power. The fuse protects the battery; if it blows, the battery will malfunction due to power loss.
2. How to determine car battery life?
- Observe the dashboard observation port: Currently, over 70% of cars have a battery observation port. The visible colors are green, yellow, and red. Green indicates that the battery is normal, yellow shows slightly low power but that normal operation is unaffected, and red signals that the battery is unusable and needs replacement.
- Measuring Battery Voltage: Use a voltmeter or multimeter to check the car battery voltage for replacement needs. For a 12V battery, the no-load voltage should be about 12.5V, full-load voltage should be at least 12V, and starting voltage should be at least 9.5V (16V for a 24V battery). If the voltage is low, the battery won’t have enough power for normal circuit operation.
3.How to use the Car Battery Checker for testing?
- Step 1: Connect the device power clips to the car battery.(Connect the red clip to the positive terminal and the black clip to the negative; the device won’t light if the clips are reversed.)
- Step 2: Disconnect the car’s negative battery pole, use AUTOOL clamps for the leakage test on the negative bus, and begin the load test.
- Step 3: Link the power supply, turn on the machine and select the battery test mode for testing.
- Step 4: Ignition start the vehicle to make the car running, get the test result through the car battery checker.
