If I started pulling them out every 6 months, I'd be accumulating
a bunch of partially discharged batteries.


True, but you know your smoke detectors will work when needed. That is why
the suggestion to use up those batteries in some other gadget that is not

Hi,
Main thing is always check them with meter to assess the condition.
I take used batteries to recycle depot once or twice a year after
gathering them up.
