Hi-capacity ‘Markyn’3.0V batteries ‘swim’ in water
-------------------PhD. Zhang developed a safety battery for RFID tags, bank smart cards, etc..
Markyn 3.0V thin batteries are 3 times higher than a same size lithium polymer battery in capacity, and 10% higher than a common li/MnO2 battery in metal case. However, chief engineer, PhD. Zhang, does not only care about long life of a Markyn 3.0V cell, but also, cares about the stability or safety. He even puts a Markyn 3.0V thin battery into water, and tests it for a long time, to see if the battery can support a light safely in water, eventually he develops a safety battery for RFID tags, bank intelligent cards, heart-monitoring cards in medical, etc, that is the Markyn thin 3.0V batteries.
Since establishment in 1999, GMB has provided quality ER, CR 123A, CR2 and lithium polymer batteries to thousands of customers include Flextronics, Midea group, Texas instruments, etc.
Apart from reliable quality, we have also spent a lot of energy on hi-safety in batteries. 3 years ago, we got a lot of requirements for batteries used in FRID tags, medical devises, bank smart cards or any other applications, in which batteries should be only very thin and but also should be much safer. Then, with several years’ hard work, our chief engineer, PhD. Zhang, has developed 3.0V safe CP batteries with a different electrolyte, rolling off the production line , now the cells can not only be made very thin, but also can soak in water safely lighting a LED. Chief engineer is a serious man, he would like his cells are aways safer than the same kind of cells, and according to PhD. Zhang’s suggestion, we give a brand name ‘Markyn’ to these thin batteries, it is his idea that we should, with our CP batteries, mark your products king in your line.
