or current leakage.
(1) Battery backup time confirmation
Refer to §11.5 “Battery Test”, and periodically perform a battery backup time test.
Depending on the results of the test, exchange the battery.
The default Setup menu setting is to perform an automatic battery test once every 6
months.

(2) Estimated battery replacement interval
Battery service life is affected by operating conditions such as ambient temperature
and the number of discharge cycles. Ambient temperature has a particularly strong
influence as indicated in the following table (refer to the table to predict when
batteries will need to be replaced according to average ambient temperature). Using
batteries after their service life has expired can cause leakage, and in the worst case
damage may result, so we recommend exchanging batteries early as a preventative
and protective step.
