The operating time may be reduced due to the utilization of the battery. The
information indicates approximate values and cannot be regarded as guaranteed
for every battery.
Replace the batteries if the operating time falls below the minimum value (see
"Battery ageing", page 17), or after 24 months (NiMH or VRLA), or after 48 months
(LFP).
The figures are based on the assumed following average battery usage:
– Applies to the internal battery without using the GS500:
400 battery discharges of up to 15 minutes per discharge during device
operation with the internal battery over a time period of 2 years.
This corresponds to a monthly usage of approx. 16 discharges of up to
15 minutes per discharge.
This corresponds to a weekly usage of approx. 4 discharges of up to
15 minutes per discharge.
– Applies to PS500 (VRLA) without the use of GS500:
400 battery discharges of up to 90 minutes per discharge during device
operation with the PS500 over a time period of 2 years.
This corresponds to a monthly usage of approx. 16 discharges of up to
90 minutes per discharge.
This corresponds to a weekly usage of approx. 4 discharges of up to
90 minutes per discharge.
– Applies to PS500 (LFP) without the use of GS500:
800 battery discharges of up to 90 minutes per discharge during device
operation with PS500 over a time period of 4 years.
This corresponds to a monthly usage of approx. 16 discharges of up to
90 minutes per discharge.
This corresponds to a weekly usage of approx. 4 discharges of up to
90 minutes per discharge.
The battery lifespan is shortened if the battery is discharged more frequently or for
longer than 90 minutes (PS500) or 15 minutes (internal battery).
This can lead to a
deviation from the maximum operating time specified in the table above.
A discharge is defined as the usage and subsequent charging of the battery.
