Stop in for a cup of coffee

Was sleeping like a rock last night until wife woke me up at midnight, smoke detector in the bedroom chirping. It's the battery back up and I haven't changed that one yet so in the middle of the night I did lol! Think battery about 5 years old
That always sucks................ Our battery backup on the alarm system has been acting up since our power outage a couple of weeks ago. It reset but the last 2 days have been acting up again. Luckily we can silence the beeping. I am going to call today.
