Company Introduction:
WaMa was founded in 2006, After more than several years development, time now we have button cells batteries, Li-ion battery & Chargers, etc.
2009 year-we passed ISO9001: 2000 certification, the company management is more perfect. Time now is an integrated hi-tech manufacturer in the R & D, production and marketing, all products have done SGS, RoHS, UL and CE certifications.
We have a great development in these years and done some more works as below.
2011 year--WAMA ELECTRONICS TECHNOLOGY Co., Ltd was founded in HongKong.
2013 year-"WaMa" brand have registered.
2014 year--WAMA ELECTRONICS TECHNOLOGY Co., Ltd was founded in Guangzhou.
We are always insisting on the business tenet: "quality first, price second". Our products have very good credit in USA, European, the South East, etc market. "WaMa" have become a reliable brand in most peoples′ heart, so time now more and more peoples to use WaMa batteries.
For future we will be insist on more higher quality and more better service
