About 2000 cycles to 80% with 100%,DOD under 20 °C~25°C
1) The only 100% safe lithium
2) Longest life battery , the 6-7 times longer therotical life than LEAD ACID BATTERY
3)No pollution at all
4)Maintainese free , half year use( charge and discharge) battery by one time that is ok.Has a shelf life of 30 years.
5)Very super lower discharge rate, the lowest discharge rate rechargeable battery in the world.
So if you have half year no use of the battery , that will not too much effect the performance.
6) Can stand deep discharge till 100% DOD . ----Even the voltage goes down to nearly 0 volt shortly, it can still remain to normal voltage .
7) Stand very high temperature .Even suitable to use in 70centigrade . It is the battery which can stand the highest temperature among all other rechargeable battery .It also can stand -20 centi degree cold temperature .
