Visual inspection

Appearance inspection is a comprehensive inspection of the external visible part of the battery, the purpose is to ensure that the battery has not been damaged during the production process and meets the quality standards.

Visual inspection

The appearance inspection is the first step to ensure that the battery meets the quality standards before leaving the factory. Through a comprehensive inspection of the battery appearance, potential quality problems, such as physical damage, corrosion, pollution, etc. can be detected early, which may lead to reduced battery performance and even cause safety accidents. In addition, the appearance inspection also ensures the traceability of the battery and the integrity of the information, ensuring that each batch of batteries meet the production requirements, and providing a reliable guarantee for subsequent functional testing and use.

Main aspect

Surface inspection

Check the battery case for visible cracks, scratches, dents, or any external damage. Damage to the housing may affect the structural strength of the battery, resulting in battery leaks, short circuits, or other safety issues.
Check the surface of the battery for stains, oil stains, or signs of corrosion, which may affect the external protective layer of the battery, thereby affecting the durability and safety of the battery.
Check that the surface coating of the battery is uniform and that there are no peeling or bubbles, which may indicate quality problems during production.

Identification check

Check that there is clear and accurate identification information on the battery, including battery model, production date, batch number, etc., to ensure that the label is intact and complies with relevant production and safety standards.
Make sure the sign is in the right position, easy to read and not easily worn to ensure that critical information is not lost during use and transportation.

Contact port check

Check that the battery contact ports, such as electrodes, terminals, and contact points, are in good condition. Ensure that they are not corroded, oxidized, or deformed to prevent battery faults caused by poor contact.
Ensure that the size, shape, and position of the contact ports are consistent with the design requirements to ensure that the battery can be properly connected to the device or battery pack.

Check the battery internal structure

Check the tightness of the battery case for leakage or damage. The tightness of the battery is essential to prevent the leakage of internal chemicals and the entry of external contaminants. Ensure that the battery port is sealed in good condition without any loose or defects to avoid short circuit or safety problems caused by external substances invading the battery.
