4) Maintenance, Storage Battery Replacement, Disposal
The PS124 buffer battery does not require any maintenance; how-
ever, in case of long periods of inactivity, it should be disconnected
from the system and stored in a dry location.
Storage batteries should be replaced whenever their autonomy is
significantly reduced as a result of aging. This operation may only be
performed by qualified technicians; please contact NICE customer
service.
WARNING: storage batteries contain lead and other
polluting substances; certain electronic components may
contain polluting substances: do not dispose of them with
other common waste. Use the disposal methods estab-
lished by the regulations locally in force.

5) Technical Characteristics
Nice S.p.a., in order to improve its products, reserves the right to modify their technical characteristics at any time without prior notice. In
any case, the manufacturer guarantees their functionality and fitness for the intended purposes.
Note: all the technical characteristics refer to a temperature of 20°C.
Note: the performances of lead-acid storage batteries are affected by their operating conditions: temperature, absorbed current, state of
charge and age of the storage battery may cause significant variations in the data shown below.
PS124 buffer battery
Type:
24V battery kit, complete with battery charger, suitable for powering gate and door automation systems in the event of mains power
failures.
Technology adopted:
Storage of electrical power by means of maintenance-free hermetic lead-acid storage batteries
Charge/discharge voltage:
28V at maximum charge; 16V at maximum discharge (when it is totally exhausted, the battery is disconnected
automatically)
Current delivered:
Rated 4A; 7.5A for 3 seconds, starting current

Approximately 16 hours
Storage battery life:
Estimated at 4 ÷ 6 years; or, over 1000 cycles for 30% discharge depth, over 500 cycles for 50% discharge, over
200 cycles for 100% discharge.
Ambient operating temperature:
-20 ÷ 50°C (storage battery efficiency decreases at lower temperatures: at -10°C efficiency is 30%;
storage battery lifetime decreases at higher temperatures: at 40°C, lifetime expectation could be reduced to 2 years.
Use in acid, saline or potentially explosive atmosphere:
No
