Technical data
Device with power supply unit PS500
(8418950)
For charging subsequent to storage
For storage up to 6 months –15 to 25 °C (5 to 77 °F)
For storage up to 3 months –15 to 40 °C (5 to 104 °F)
Information on the batteries The technical specifications of the battery man-
ufacturer regarding the maximum storage life
refer to a relative humidity of 45 to 85 %. If it is
stored outside of these conditions, a battery
test must be performed before the device is
used. Completely charging the battery every
6 months at the latest is recommended. Several
charge cycles and discharge cycles may be
required as a battery test in order to completely
reactivate the electrochemical composition after
long term storage.
Depending on the accessories used, more
stringent ambient conditions may apply.
Observe the corresponding instructions for
use.
8.2 Operating characteristics
Batteries
The battery runtime applies to fully charged bat-
teries and during ventilation in accordance with
ISO 80601-2-12:2020 as well as at an ambient
temperature of approx. 22 °C (71.6 °F).
The battery runtime information after
50 discharge and charge cycles refers to the
shortest battery runtime under the test condi-
tions specified in the standard.
Low temperatures may reduce the battery run-
time.
The charging time applies to new and com-
pletely discharged batteries during ventilation
without GS500. The actual charging time
depends on the battery charge.
If the GS500 is operating or the ambient tem-
perature is high, the battery charging process
may be restricted or interrupted.
