KAPower is a electrochemical capacitor (aka supercapacitor or ultracapacitor) and all specifications subject to change without notice.
* Module can be kept at this voltage for a short period.
** Short-term discharge of the module down to zero volts is possible. However, it should be stored at a voltage not less than the minimum voltage specified.
*** Pulse Cranking Amps (PCA) is measured at the rated voltage for the defined amount of time. Engine starting is considered to be a pulse power application because it requires a high rate of discharge for a short duration.
**** Operating temperature is dependent not only on the ambient temperature, but also on the module operating mode. High charge or discharge cycle frequency and high charge or discharge currents produce higher temperatures. To insure guaranteed cycle life of the capacitor module, internal cell temperatures should not exceed 131 F (55 C). Module operation at temperatures above 131 F (55 C) may temporary result in a reduction of the modules capacitance and delivered energy. Capacitance and delivered energy can be fully restored by re-charging the capacitor at temperatures below 131 F (55 C).
