NOTE
The super capacitor is only charged partially when shipped. Therefore, after
powering on the system, the super capacitor will start charging to its full capacity. It
normally requires approximately twelve hours for the battery to be fully charged. If
the battery is not fully charged, well after 12 hours, there may be a problem with the
battery and you should contact your system vendor immediately. You can also check
the status of the battery module via SANWatch or the firmware (please refer to
respective manuals).
