The Euro 46 panel takes a 12 volt 7ah sealed lead acid battery like
the one at the link below. It's 1 battery in the small version and
possibly 2 in the large version.

Just be aware that the tamper switch in the panel will likely cause
the alarm to go off when you open the case so either put the alarm
in engineer mode (if you know the engineer code) or be ready to
hold the tamper switch in when you open it. Also switch off the
mains supply to the panel before opening it as the live terminals
are exposed inside.
