”-charging characteristic for
surveillance-free, fully automatic con-
tinuous operation (e.g. longer breaks,
wintering or seasonal operation)
• Parallel and buffer operation: If the bat-
tery is used at the same time, the bat-
tery simultaneously will be charged or
retained in full condition
• Multiple protection, against overload,
overheating, overvoltage, short -circuit,
reverse-polarity and incorrect operation
(Attention: no reverse polarity protec-
tion at the starter battery connection!)
Automatic lead-battery regeneration in
mains operation at long idle times
against harmful acid layers (twice a
week)
• Charging cable compensation: voltage
drops on the charging cables are auto-
matically corrected
• Charging possibility of deeply discharged
batteries (0 V) with initially reduced char-
ging current until battery voltage rises
above 9 V
• Integrated on-board network filter for
trouble-free parallel operation with solar
systems, wind and gasoline generators,
etc.
• Temperature-compensated charging: De-
pending on the temperature, the ex-
ternal temperature sensor influences
the charging voltage for lead batteries
and the charging current for lithium
batteries for monitoring-free and gentle
charging
• The enclosed temperature sensor can
be used universally for all battery types,
regardless of the manufacturer. If a lithi-
um battery from BÜTTNER ELEKTRONIK
is used, the temperature sensor built
into the battery preferably is to be used.
The BCB then establishes contact with
the sensor and ensures operation in the
optimal charging window.
