1) Safety: Currently the safest Li-ion battery, non-incinerated under over voltage of 30V charge, non-explosive under piercing.
2) Environmentally friendly. 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.

Notice
Don’t near the hot source and don’t under the sunshine.Don’t charge in the sealed container.No short circuit. It should be addition charge if you don’t use, and single charge per three months, to avoid irreversible sulfating. The battery should be changed when the battery jar broken or the electrolyte omitted, to avoid acid corrosion.Don’t store in the space of acid gas.You should be careful and regular check when use the battery. To avoid the battery don’t work. You should change the battery if the capacity is not full or has been damage, especially after one year using.Don’t put the battery in the fire, or it will explode.Please use cotton cloth to clean, if the battery is broken down and leak electrolyte. Please wash your skin when touch the electrolyte.Don’t clean the battery by using the organic solution. (e.g. petrol)Battery details and our factory :
