OK, so I changed the 9 volt batteries in all my smoke detectors. I tested the old batteries and they had either 80% or 90% power remaining. So what do you do with these batteries now??

Clip them together, make a belt out of them, and be a suicide bomber next halloween. You need about a hundred to do it.

If they are still 80 or 90% good why not just put them back in the smoke detectors?

Charity will use them in smoke detectors that kind of work.

How did you test them? To truly test a battery, you need to simulate a load. Many batteries will show good voltage with a meter, but loads drop them fast. That's why they say replace them annually. so there will be enought current capability to actually sound the alarm if needed. But, to also answer your question, I cycle mine to the only other thing in my house that uses 9 volts, my alarm clock for back-up.

And ultimately, if your town has a hazardous waste collection system, recycle them so they won't go into some landfill and contaminate the groundwater supply.

get some Pak-Lites and use the old batteries in that way - see link http://www.9voltlight.com/

Use them in something that doesn't have life or death consquences when
they fail.

WOW!!! The only guy in America who actually changes batteries in his smoke detector when he resets his clocks. Got any other sick habits like checking air pressure in your tires?

Do you have a church near by? do they use Wire-less? Microphones, guitar packs etc. They can use them. Our old church, put on a dinner theater. We'd buy a brick of the 9V batteries, so no wireless dies during the shows, we changed them every show! Tossed the lightly used 9V's into a box and used those the whole rest of the year.

I've been in a fire and I make jokes about detectors all the time. My unit had 2 and three other units were affected. That's at least 5 detectors and none sounded in our fire. (One of mine that I then carried to our temporary digs sounded the next night--24 hours after the fire.) I also have lost a friend to another apartment fire, and the story was no detectors in that complex of 6 units sounded.

Those stories are anecdotal, but empirical tests show the ionization detectors take 20-30 minutes on average to sound. They are only really indicated for slow-smoldering fires, and not fast moving blazes. Do not rely on them with unquestioning faith to save your life. They certainly may, but you need several other plans in place in case of fire. The newer dual detectors with optical sensors are quicker, but also more expensive.

Back on point, with the legislated lengthening of Daylight savings, I wonder if the clock change time is the best for battery changing. Maybe it should be the Equinoxes.

That was the first thing I did with them...

This probably does not answer the question exactly but you can get a feel for the relative brightness by comparing various reviews of lights to the Pak-Lite review on the website Flash Light Reviews - Pak-Lite's review is on this link: http://www.flashlightreviews.com/reviews/pak-lite.htm

I used a ZTS Pulse Load multi battery tester. The used batteries came out 80 to 90% having been replaced last year and never sounded since they were installed.

I "pulse" tested all the new batteries before installing them. Something interesting happened when I "pulse" tested a package of brand new 9 volt batteries. They failed the pulse test but passed one of my old style mechanical/analog testers. I am not going to use these in my smoke alarms. Instead I will save them for some non-critical task.

You could wire them all in parallel and make one really big 9v battery to power Christmas tree LED lights.

I put mine in my 110v clock/radio for its BackUp Battery, will keep my clock right when or if the power goes out. Not really a critical deal anyway.

I just heard something else interesting about 9 volt batteries. That there are actually six 1.5 volt batteries inside a 9 volt battery.

Thanks, that did help. I'll have to get one of these! :-?

You might want to check snopes before you tell that one many times. :)

Panzer:confused:
How about replace your alarm clock backup batteries with your smoke detector batteries. Ancient 9v remotes.

Other than that...lick them.

Likewise, 9-volt batteries also contain individual cells, but again those cells arenít necessarily batteries of a kind that the typical consumer would have much use for.

Is the above what your were refering to???

The Snopes issue may be that this info spawned a series of hoaxes that other battery types were filled with end-consumer smaller batteries.

Make one of these cool 9V led lights, I did. Mine are better and lighter, no off and on switch.
