Arrived home in the middle of a power cut last night and noticed our alarm box wasn't flashing red like it normally does underneath. Opened the door to silence. When the power eventually came on the fault light lit and the display says battery fault.
Anyone know if we can fix this ourselves and how to go about it. Don't really want to pay €100 to get an engineer out.
