What is lithium battery UL certification?

Battery UL certification is usually divided into two types, UL1642 and UL2054.

UL1642 is the standard for lithium battery safety introduced by the American Safety Testing Laboratory Company (also known as UL Company, Underwriters Laboratories Inc.) in October 1985. The first version of the specification safety standards for lithium batteries, is most widely international certification assessment of lithium batteries in all kinds of fault cases authority standards for the safe reliability of battery, mainly for batteries (cell).

UL1642 test projects include short circuit test at room temperature, 55 degrees short circuit test, overcharge test, compression test, weight impact test, mechanical shock test, vibration test, hot box tests, temperature impact test, high altitude simulation test, the ejection test, etc.

UL2054 is mainly aimed at Lithium battery pack or the lithium battery package (battery pack).Applicable to products used as power supply in a (not charged) and secondary (rechargeable) battery. These cells can be made of a single electrochemical cell or two or more in a chemical reaction to convert chemical energy into electrical energy Lithium ion batteries in parallel or in series.

UL2054 test project mainly includes the electrical testing (short circuit test, abuse of overcharge test, overcharge, discharge test, limited power source) and mechanical test (compression test, impact test, the acceleration test, vibration test) battery shell crash test, 250 n, the static test, drop test, mould pressure release test, the test of fire, mass ejection temperature cycling test, environment test, high temperature test, test, etc.

UL are divided into three kinds of column name tags: UL listed, C - UL listed marking, C - ULUS column name tags, mainly according to their market to distinguish between different countries.

UL listed marks is by far the most commonly used, for example, the type of tag is usually seen in the following categories of the products: electric appliances, computer equipment, stove and heater, fuse, power panels, smoke and carbon monoxide detectors, fire extinguisher and automatic sprinkler system, personal flotation devices, such as life jackets and life buoy, bulletproof glass and other thousands of products.

C - UL column name tags, applicable to the product that sells on the market in Canada. Can see this sign on the following types of equipment, appliances and equipment, vending machines, home security alarm system, lighting equipment, and many other kinds of products.

The C-ULUS listing mark meets both US requirements and Canadian requirements.

UL's certificate report has no expiration date, and it is maintained according to the factory inspection and certificate maintenance fee. If the factory is inspected one season, it needs to have a factory record.
