6.2 Batteries - General
The service life of the battery is from 3 to 6 years, depending on the operating conditions
(mainly temperature and number of discharge cycles).
As a healthy battery is critical to the performance of the UPS, it is advised to regularly perform
a battery test to ensure failsafe operation (see section 3.3.3). When the condition of the battery
is critical, a
'replace battery'
alarm will be activated (see 3.1, LED 11). Replace the batteries as
soon as possible. See 6.3.
