and the fans) in regular intervals (at least every 6 months).
CAUTION:
Before going through the next step disconnect
the PROTECT C. from the mains.
10.1 Charging the Battery

The complete charging time of the battery after a length
discharge period depends, above all, on the number of
additional external battery units.

Two additional battery units approx. 16 hours
