Detection method for battery quality: 1. Visual inspection: When there is a problem with the battery, there are changes, such as leakage, swelling, bulging, or severe damage. This situation can determine that the battery has a problem; 2. Connect the load: For example, for a 12V battery, you can find a 12V lamp or electric motor to connect it and check if it rotates. If it does not rotate, the battery may have problems; 3. Connect battery charger: Observe the reaction of the charger. If the battery is good, the charger will light up a red light and start charging. If there is a problem with the battery, the charger will only light up a green light and the battery will heat up; 4. Use a multimeter to test voltage: The red probe of the multimeter contacts the positive pole of the battery, and the black probe contacts the negative pole of the battery. Adjust the multimeter to the DC voltage range, and then start measuring to see if the value is the rated voltage.
