Hello Amund:
To determine whether a battery is a LPS, perform the measurements specified in EN 60950-1. A lead-acid battery will easily exceed both the 8-ampere criterion and the 100 VA criterion. The ratings you quote, 12 volts and 12 ampere- hours, already tell us the battery is not LPS. If you put a fuse in series with the battery, the circuits on the load side of the fuse can be LPS. Choose the fuse in accordance with the EN 60950-1 requirements. The circuits from the battery to the fuse are not LPS and will need to be in a fire enclosure.
