Recalculate your stats ??? :)
Most detector batteries will be replaced once per year, in daylight,
carefully, when sober. i.e. regular maintenance, not midnight drunken
panic. :) You can also get lithium batteries that last 7-10 years,
so, as that is about the expected life of a detector, you just replace
the whole unit.
A local handyman can do all that for elderly people.
A house fire is a much more significant accident than maybe falling
off low steps while replacing a battery. Most people will rarely fall
off low steps, and even if they do, most will not come to any serious
I think that if battery changing was causing many serious accidents
there would be a public reaction to all the deaths and injuries.
Similar to the campaign that got the detectors installed in the first
