Product & Factory Certificates

All batteries are require related certification apart from lab testing, such as voltage, current measure, and each countries have different certificate demand.

Clients are welcome to have any 3rd party certification company verify our batteries or the factory documents.

We have been working with UL, TUV, SGS certication lab. All batteries approved by UL1642, UN38.3, IEC62133, PSE, KC, CB, MSDS certificate or report.

DB Technology works with some of the top brands around the world such as Bose, ZAGG, Victrola etc. We came to HLC with a very specific set of requirements needed to replace a defective battery from another “low cost” supplier. Henglichi not only met or exceeded all the specifications, including safety tests, they actually beat the previous vendors price! HLC is a great partner.

SailiDevelopment and Quality Manager

Just what I needed to replace my old batteries, these are good quality batteries with a high power rating. The batteries are working really well as none have yet run out of charge for what they are being used for. I bought over 30x batteries of this company for kids toys and hand held home items. Cheaper then branded batteries and works the same. Highly Recommend!!
