3.5 Battery protection
The EFOY COMFORT fuel cell has automatic battery protection when the
EFOY COMFORT fuel cell is switched off.
Battery protection is activated automatically if the battery voltage drops
below a certain level (11,2 V for lead-acid batteries and 11 V for LiFePO4
batteries ) for more than 15 minutes. "Battery protection" mode ends as
soon as the voltage reaches 12.8 V.
The battery protection function provides deep discharge protection for the
battery, even when the EFOY COMFORT fuel cell is switched off and does
not take over the charging function.
If you want to switch off the EFOY COMFORT fuel
cell after the battery protection function has
started, press . The function is re-enabled au-
tomatically when the device is switched on or is
opera-ted in automatic mode.
CAUTION!
If you stop protective charging manually, battery protection is disabled
until the next time the fuel cell is started. Deep discharge may damage
your battery.
