The batteries - 2 x 12 V, 28 Ah (e.g. Panasonic LC-P1228AP) - are
placed inside the control unit. Larger batteries (< 65 Ah) have to be
placed outside the control unit, e.g. in a separate battery cabinet, etc.
The control unit supervise and charge the batteries and a fault will be
generated for any trouble with the batteries.

UL94V-0. The batteries are normally maintenance-free but the
producer's instructions shall always be followed.
The ambient temperature affects the battery's capacity, self discharge
and life span. The temperature should preferably not be higher than
normal room temperature (approx. 20-22°C).
For highest safety, the batteries used in a fire alarm installation should
not be more than four years old.
