Most take the same battery as things like deer feeders. So academy, producers, think harbor freight has them. Usually a 12v sla. Take a picture and shop. You can always do battery plus and pay a premium but make only one stop
Resurrection because I have been trying to get to someone local at ASC for 4 days without luck. System fault going off every 4 hrs 24/7 and very sleep disruption provoking. Can't bypass as it's a smoke alarm. Anyone with a better contact than the local number (answered by an answering service). Prior email I have used isn't getting a response.
