requirements, charging automatically resumes.
During charging, do not disconnect the AC adapter before the battery has been fully

progress. You are advised to keep DCU 220 power off while the battery is being charged.
When the battery is fully charged, the Battery Charge Indicator glows green.
The two battery packs are charged in parallel. It takes approximately 5 hours to fully charge
the two battery packs when the power is off and approximately 6 hours when the power is
on (may need a longer charging time at lower temperatures).
CAUTION: After DCU 220 has been fully recharged, do not immediately disconnect and
reconnect the AC adapter to charge it again. Doing so may damage the battery.
NOTE: The battery level may automatically lessen due to the self-discharge process (0.21
% per day), even when the battery pack is fully charged (100 %). This happens no matter if
the battery pack is installed in DCU 220.
