When fully charged for approximately 1 minute at 12 V, 500 mA, the Supercap provides sufficient capacity to support a 24-channel FLEX Leg system.
SLICE system behavior will become unstable as the Supercap discharges to voltages well below SLICE operational levels. At extremely low power levels, SLICE may still have some activity that is not discernible. This is when the Supercap has a voltage between 1.0V and 5.0V. Any attempt to recharge the Supercap without a complete discharge will result in SLICE system errors as power is restored and components re-energize and reinitialize randomly.
To prevent this unstable condition, the Supercap must be completely discharged to force a complete shutdown of the SLICE system. Therefore, after each test, you must always drain any remaining capacity and discharge the Supercap completely before recharging. The Discharge Plug is provided for this purpose. Without the plug, it takes up to 3 minutes to completely discharge a fully-charged Supercap. To ensure complete Supercap discharge and rapid SLICE system shutdown, insert the Discharge Plug immediately after the test and wait several seconds after the LED goes dark before recharging the Supercap.

For how long will a fully charged supercap run a 12 and 24 channel system please ?
I always set a recording window of 1 second for a 12 channel system and 0.5 seconds for a 24 channel system.
I think those are good settings providing a safe margin.
The supercap is 0.46 farads and charges to 10.5Vdc
