Non-toxic materials. ?3)Powerful.4)Long cycle life: 2000 cycles remain 80% capacity. Other Li-ion battery is only 300-500 cylces. Ni-Cd /Ni-MH and Lead battery is also only 300-500 cycles. ?Stringently integrated with international management standard,?our Batteries have secured ISO9001:2000, ISO14000, CE, UL, SGS/RoHC, RBRC homologation and especially TS16949:2002 certificate issued by NQA for EV cars batteries design and manufacturing. Our batteries are well sold to Western Europe, North America, the Oceania, the Middle East, East Asia and Mainland China.APPLICATION:?CERTIFICATES: http://www.optimumnanolithiumba...50-cylindrical-cell.html
