At what point do you stop throwing out good batteries and realize the device is defective??:confused3:

When I have a new package of batteries, and the device still doesn't work. Most of my stuff that is battery operated is used enough that I know when batteries are getting weak. Flashlights are tested weekly, if I am not using them that often. Book lights are used nightly. I just don't have a lot of things that run on batteries that sit around unused periodically. And I don't store used, or older batteries in teh same location as new ones, so no confusion there.

Got a couple of new AA's out of the fridge, and they passed the test. No bounce and stood upright. There were eight AA's in the sound system cabinet from the last time I changed them out in the cordless mic's so I walked down and got them. All eight of them failed the test{and got tossed}. But since we have Sennheiser mic's, there is a readout on the controller that shows you the battery level.

Very simple process for ensuring flashlight works when you need it........when not in use......open up flashlight.....turn the top battery around.....store flashlight in that position. When ready to use.....flip the battery back around. Your batteries will last a very long time.........we teach this easy trick in our hunter education classes and survival classes. Been using the same flashlight and batteries in my hunting back pack for the past three years. Try it.......:thumbsup:

Wouldnt that up the amperage if someone were to use it accidentally?? Possibly burn something up??
IF 2 battery light, thats 3v. If one battery is backwards, 1.5v at double the current? OR do the batteries not make enough contact on the flat (negative) end?

Might if you left the on switch on for an extended length of some time I suspect. Never had a problem in any of my flashlights.....been using this method for years. If you forget to flip the batteries.....you'll know it as soon as you turn on the flashlight.....simply turn it off...flip the battery and you're good to go. I've had flashlight batteries last for years this way.....never had a problem.

Okay this thread was informative and made me laugh pretty hard. Thanks all! Tonight I think I will correlate the number of bounces to voltage level. I have a box full of used AAs just waiting to be metered and dropped!

Bugger! All of the batteries in the house are good and that's after metering them.
On the downside: I can't fully confirm the bounce test.
On the upside: All of my remotes & torches have good batteries in them!
Conundrum: Is the experiment 'opposite' South of the equator? Hmmmmm.....
