Cylindrical Cells
• High Performance —High theoretical capacity of 170mah/g and high practical capacity as high as 165mah/g
• Long Cycle Life: up to 2000 cycle life (8x of Lead Acid and 3-4x of Li-ion)
• Extremely Safe/Stable Chemistry: no explosion & will not catch fire under collision over charged or short circuit; hi thermal stability of phases up to 500C
• Long Service Life: Around 5~6 years
• Wide working temperature range: From -4 F to 150 F (-20 C–+70C)
• Flexible & Small Form Factor: 1/3 weight of lead acid and 64% of NiMH
• High Rate (Power) Capability
• Environmentally Friendly Non-toxic, non-contaminating and No rare metal
• Fast Charging: fully charged in a very short time ---2C fast charge within half hour
