Would like your opinions on this.

Got my son and daughter-in-law a First Alert Smoke/CO alarm for their house.

They are both as non-technical as you can imagine.

Thought a bit about what to tell them to do if the Alarm goes off,
falsely. Apparently, this is a fairly "common" occurrence.

Alarm has a 10 year, non-replaceable, sealed battery.

Did a Google search, and these batteries are apparently Li-Ion.

The alarm also has a small slider switch, with a break-away tab in the
back, to permanently disable the
battery, and any ringing.

My guess is that at 3:00 AM, it's not a very good option for them to
start playing with.

So, I told them to just dump it in a bucket of water.

But, having found out that it is a Li-Ion battery, this doesn't sound
like a good idea anymore.
Explosion hazard in water, etc. ?

Any thoughts on this bucket of water approach, etc. ?
Other ?


I don't think putting the smoke alarm in a bucket of water is a good idea. I have installed these types of alarms. The battery is not serviceable or accessible.

I think that some of these models have a hush feature for false alarms. You just have to push the test button and it gives you a few minutes of delay. Check the instructions.

I seem to recall that the disable switch is to be used at the end of the smoke alarm's useful life before disposal.
