To verify whether a lithium manganese battery certificate is still valid, match the certificate name and number with the product, applicable country, and certification scope, then confirm that the issuing record has no stated expiry, suspension, or replacement. For Vinnic manganese dioxide lithium batteries, the available data lists UL certificate UL-US-L66112-03511-10803202-1 for the United States and lithium batteries, but it does not provide a current validity status.
Certificate verification requires a record-level comparison. The certificate name and number should correspond to the certification entry, while the applicable country and product fields should match the intended market and battery category. The supplied record identifies UL certificate UL-US-L66112-03511-10803202-1, with the applicable country listed as US and the applicable product listed as Lithium Battery.
The product information identifies the product as Vinnic Manganese Dioxide Lithium Battery and describes compact construction, stable power supply quality, extremely small self-discharge, and a compact operational temperature range of -20 °C to 60 °C. These product details help identify the product family, but they do not establish certificate validity by themselves.
Available certifications for CHUNG PAK include ISO 9001:2015, IATF 16949:2016, ISO 14001:2015, SNI, WCA, UL, Intellectual Property Compliance Management System Certification, and AEO. The UL entry is the most directly related credential in the supplied data because it specifies lithium batteries and the US market. No expiry date or active-status field is provided for these records.
For a purchasing review, the business model is described as full industrial chain, distribution, and direct sales. The stated battery MOQ is 10,000 units, and the stated delivery time is 30 days. These commercial details support supplier evaluation but do not replace certificate-status verification.
