leftover 9 volt batteries

[jlb2012]

How bright are those things?

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

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.

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.

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??

Panzer

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 aren’t necessarily batteries of a kind that the typical consumer would have much use for.

Is the above what your were refering to???

They're AAAAs:

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

Here is a link to a cool photo of the cells

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

Definitely touch them to your tongue! Who doesn't? If you just raised your hand...YOUR WEIRD! I'll bet Albert Einstein would do it, more than once at that!
