• Battery module
Type of SITOP BAT1600, SITOP UPS1100 battery modules or third-party battery
• Battery type
Make/type of battery: Pb ... lead-gel battery, pPb ... pure lead battery
• Typical ambient temperature
Typical ambient temperature of the battery in operation
• Total capacity
Total capacity of the installed batteries.
• End-of-charge voltage at 20 °C
The end-of-charge voltage defines the maximum battery voltage during the charging
phase. When reaching this end-of-charge voltage, the charging status changes from
"constant current" into the "constant voltage" phase. The adjustable end-of-charge voltage
is applicable for a battery ambient temperature of 20 °C. SITOP UPS1600 adapts the end-
of-charge voltage corresponding to the connected SITOP BAT1600 or SITOP UPS1100
depending on the battery ambient temperature and the battery technology. For third-
party batteries, the adaptation is based on configuration parameters battery type, typical
ambient temperature and temperature coefficient.
• Temperature coefficient
Relative dependency of the end-of-charge voltage on the ambient temperature
• Duration of the constant floating voltage charging phase
Duration of the constant voltage charging phase
