Hello,
I have just replaced my home smoke alarm batteries about 6 months ago. They are alerted beeping again yesterday. I disconnected batteries and measured them, all are read 9.35 vdc they are good reading. Why did my alarms beeped when my batteries are in good reading? When I replaced brand new batteries, no more beeped. There are 120vac and 9v batterry in my smoke alarm unit.
can any one help and explan why they beeped while all batteries ar good reading?
Thanks in advance
