Twice a year? WTF
It doesn't matter. EVERYTHING IS FOR THE KIDS
I got 2 new smokes and 1 new co this time around. $47 not bad.Also if your smoke detector is older than 10 yrs, you should replace the entire unit as it loses sensitivity with age.

I love youJust measured my bedroom smoke detector's current draw... 12uA. 450mAh energizer industrial alkaline / 12uA = 37500 hours = 1562.5 days = 4.2 years.
6 months? fuck that.
I imagine this varies from detector to detector though, possibly substantially.
I think the concern is that people generally buy those 10 for $1 dollar store batteries with top notch Chinese sweat shop "quality control".Just measured my bedroom smoke detector's current draw... 12uA. 450mAh energizer industrial alkaline / 12uA = 37500 hours = 1562.5 days = 4.2 years.

but still, they beep when they're low. why change them before then?
conspiracy perpetrated by battery manufacturers
We will change ours at three in the morning if they start beeping, it's that annoying.mine are annoying enough that i change them.
chances are the people who let them beep aren't going to change them anyways.
Do you have the style that beeps, then right as you are drifting off to sleep it beeps again just in time and in such a manner as to completely wake you up?We will change ours at three in the morning if they start beeping, it's that annoying.
