Note
From the instant in time when the SITOP UPS1600 is switched over into the buffer mode, the
buffer current actually measured is used to determine the expected buffer time instead of the
expected buffer current.
Maintenance
Parameter
R test interval (from V2.1 to V2.3) [h]
The new R test (from V2.4) is performed once a week after short-term recharging. Therefore,
it is no longer necessary to set the R test interval.

• 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-
