2.Low self-discharge <3.5% per months

3.Free of charge memory

4.Steady discharge and charge performance.

5.Outstanding thermal stability

6.Wide temperature performance

7.Short circuit protection

8.Overcharge and discharge protection

9.Overcurrent protection

10.Easy carrying and installation - can be carried and installed in any direction

11. Fast charging - about 4~6 hours to be fully charged

12.Lighter weight - 1/2~1/4 in weight compared to LA batteries

13. Require no change to a lead-acid battery charging system

14. Better safety - mild warm, no explosion and firing, free of leakage

15.Environmentally friendly - no poisonous lead, no acid, no heavy/rare metals

16.No gasses during charge, free of leakage and pollution
