Overview:
Winter is gone and spring returns. In this season of great vitality, MCM is stepping to a new stage. Since 2007 when MCM started to conduct UN38.3 Lithium batteries transporting certification, we have provided batteries certification services for customers all over the world for 15 years. The great progress during the half and a decade is the result of support from our customers. Therefore, in the future, we will make our services more rapid, more excellent and more systemized.
In order to optimize our services and capability, we started to plan for an upgrade of our lab and offices. We select the new site, conduct design, construct and choose new equipment, all with careful consideration, holding the faith of “Surprise our customer by building the first grade laboratories”. Our customer will be presented with a safer, more efficient and brilliant lab.
New Site:
The new address locates on Building 2, Zhong Er Industrial Zone, NO.45 Shiguang Road, Zhongcun Town, Panyu District, Guangzhou.
The new base will takes 10-15 minutes of traffic from Hanxi Changlong station (line 3), Zhongcun station (line 7) or Guangzhou South railway station. It also reaches Xinguang High Way and Guangming Highway. We are on a fast and convenient traffic net! MCM welcomes your visit!
New Laboratory:
The new laboratory is as large as 5000m2. There are five separated areas, respectively for portable batteries experiment, electric vehicle batteries/storage batteries safety experiment, electric vehicle batteries/storage batteries performance experiment, IT/AV products experiment and sample storage.

Certification of electric vehicle batteries/storage batteries
The preparation of new site and equipment is to perform more comprehensive services. We are expanding our business and get deep into international certification with TUV RH of storage batteries and electric two-wheel vehicles batteries. Meanwhile we cooperate with EPRI in power grid storage. We will be able to test products of more elaborated design. We will also start projects of certification in transport area, and coordinate with CAAC to gain more resources of air transport.
