Mitel bluetooth headset project
2021-06-18
Project name: 552035 3.7V 350mAh lipo battery are used in Mitel 6940 IP phone and spare bluetooth headset.
Detailed introduction: We started to contact with Mitel on Nov. 22th,
2014. They sent us an inquiry about 3.7V 350mAh-450mAh lithium polymer battery
used in their developing bluetooth headset project. The battery need to be with
UL and IEC62133 certificate approval, and the size should be within T = 6.2mm (max), W = 22mm (max), H
= 41mm (can be longer if needed) . As per their requirements, we suggest
our ready UL1642 cell model 552035 3.7V 350mAh, which will save much UL1642
certificate fee for our customer. Mitel accept our suggestion, but they also
need the battery pack with UL2054 certificate.
According to our cooperation experience with Philips over 5 years and international common practice, lipo battery doesn’t need to make UL2054 certificate as it’s just a part of finished products for US market if the cell has UL1642 approved. We advised them that this certificate is not necessary, but they still insist on making UL2054 certificate for 552035 3.7V 350mAh lipo battery pack, even though the high expensive certificate fee of UL2054. During the past 2 years, we continued to provide several battery samples for Mitel to develop their IP phone and bluetooth headset project. They tested our battery samples and satisfied with our battery quality. But they suspend this project about 1 year.
In November 2015, they re-started the project and we received our vendor number: 148688. Then we arranged another battery samples for their final design. At the begining of 2016, they paid the certificate fees and request us to make the following battery certificates, like UL2054, IEC62133, ROHS, REACH, UN38.3 etc. UL2054 testing is very strictly and request battery with high quality. It took about half past 2 month to finish UL2054 certificate. After all certificates finished, Mitel start their trial production in July, 2016. In August, they recommend their partner Flextronics to us, and we also become Flextronics Supplier in China (our Flextronics BP Code: SPS03130U).
Even though it’s long time for developing a new project, but we have confidence for our clients and do our best to offer a good service and best solution for them.
