Can 10-year smoke alarms be refurbed with a new battery when ten years is up?

Or is the battery sealed? Do they sell ten year batteries for this?

In my experience they are sealed, and in fact there is no easy way to disarm one in the event that one is sounding the alarm. A hammer was the best option in my case.

I heard, no confirmation, that the sensor is considered no longer functional at that time frame, so-No

I think the radioisotope in the sensor is no longer strong enough, but I may be misremembering.

As I said in the battery thread, I have had those poop out long before ten years, with the thing beeping, indicating a dead battery. The only option to get it to stop beeping is to pull the little switch to disable it, thereby making it junk.

Dennis,

I wouldn't even if it was feasible. No guarantee it'd work properly and it'd most certainly wouldn't be covered under warranty. I'd be inclined to say in the event of a claim, an insurance company would use a DYI refurbed smoke alarm as a reason for denying it. I'd just spend the bucks for a replacement and call it done.

This is the right answer.

OK. These things have radioactive americum as a component of the sensor. It is a radioactive isotope, and has lost its effectiveness at 10 years.

Recycle it properly, buy a new one, and get on with your life, safely.

not worth it to be cheap with safety devices.

Easy, boys.

I don't know that Dennis is keen or was sold on refurbing the alarm, but wondering if the battery could be replaced certainly seems like a good idea, without the additional information.

How often do you guys replace the cheap, 9V battery detectors?

Other than changing batteries, this is the most attention I've paid to them.






I am that Masked Man.

Your boos mean nothing to me, I've seen what you cheer for.

Insisting on your rights without acknowledging your responsibilities isn’t freedom, it’s adolescence.

I've been to the edge of the map, and there be monsters.

We are a government of laws, not men.

Everybody counts or nobody counts.

When a good man is hurt,
all who would be called good
must suffer with him.

You and I have memories longer than the road that stretches out ahead.

There is no safety for honest men except
by believing all possible evil of evil men.

And hope is a lousy defense.

Smoke detectors based on an ionization detector use a radiation source, photoelectric detectors do not. The first type should be recycled through the manufacturer or other recycler licensed to handle them.

Thank you. I have no experience with this and didn’t want to be a chump and throw away a perfectly good alarm and find out later all you have to do is plug in a new ten-year 9V battery and you’re ready to go. (They do it with cars, you know.) and they do make ten-year 9V batteries.

and, for the record, I replace my smoke detectors every 10 years, and our CO alarms when the batteries die.

And have 2 fire extinguishers in the house, 1 per kitchen, and one huge ABC in each garage, and a big CO2 in the outside garage as well. I have a guy who services them for free.

Safety is dirt cheap compared to the alternative.

these are inexpensive life saving devices.

Don't screw this up.

The National Fire Protection Assn recommends replacement every 10 years. Apparently there's a 30% chance of failure at that point. Seems to me that we should be replacing them earlier if that statistic is correct. They say to check them monthly to be sure it works. But, I wonder if testing them checks all of the aspects of their operation.

smoking match. easy peasy

our cooking sets the upstairs ones off often enough that I consider that a test. Really doesn't take much smoke at all either.

Look at the backside of the detectors. Ionization type typically have an expiration date on them.

On a slightly different tangent, a fire fighter teaching a CERT class to us, recommended replacing a home fire extinguisher every ten years even if the gauge showed full. And that you have two fire extinguisher wuishers at each spot. Noting that failure rate for them was like 30%.
