We buy the fire alarms with built in long lasting batteries, they are meant to last 10 years but they all die after 18 months. You can’t replace the batteries and they won’t stop going off.
anyone else have this? Any reason why? We buy good brands from B&Q, fire angel which surely should last.
We have humidity problems but run dehumidifiers regularly. I’ve got a carbon monoxide alarm that’s lasted 8 years.
