How to Test the Condition of a Car Battery?

[Lois]

Methods to test a car battery: 1. Connect the positive and negative clamps of the battery tester properly—red clamp to the positive terminal and black clamp to the negative terminal of the battery; 2. Once connected, the battery will display its current static voltage; 3. Press the Enter key to select external testing; 4. Press the Enter key to choose a standard lead-acid battery; 5. Select the measurement standard type based on the battery label; 6. Use the up and down buttons on the battery tester to adjust the test rating value to 550A; 7. After setting the appropriate rating, press the Enter key to confirm and start the test. The car battery is an essential component of a vehicle and can be categorized into traditional lead-acid batteries and maintenance-free batteries. Batteries use lead-calcium alloy for the grid frame, resulting in less water decomposition during charging and lower water evaporation. Additionally, the sealed structure of the casing minimizes the release of sulfuric acid gas. Compared to traditional batteries, these batteries offer advantages such as no need to add any liquid and longer power storage duration.
