Lithium Ion Capacitors suit server backup power sources.

Combining strength of lithium-ion secondary batteries with Electric Double Layer Capacitors, Cylindrical Lithium Ion Capacitors provide max rated voltage of 3.8 V and come in 4 capacitances of 40, 100, 200, and 270 F. Units have no risk of thermal runaway, and have extremely low self discharge, even in high heat environments. Operating from -25 to +70
