How to test any battery..AA, AAA, C or D ---Fast and Easy

[LD1]

I put the batteries in a device, if it works, they are good! If not, I throw those away and try different ones! :laughing:

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!

They say, "It don't take much to entertain some people."

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.....

Thanks for posting.

Personally, I will stick with my analog RadioShack meter that I've had for 28 years for checking batteries (AAA, AA, C,D, car, truck, tractor, generator, lawnmower, 9V smoke detector, etc.)

I break out my digital VOM meter only when I want to use the clamp-on ammeter function.

On occasions, I will still use my father's old battery tester which is over 80 years old. It works with all AAA, AA C and D batteries and is much faster than getting out the voltmeter, unwrapping the leads, turning it on, testing, turning off, wrapping up the leads and putting it up.

PS And it doesn't even require batteries to operate.

Don't know if this works ...I have not tried it yet....but I will..

How To Test a AA battery, Easiest Way For Any Battery Fast, Easy! - YouTube

Brin....I have always tested batteries with a multimeter....and something in the video seems weird: I have tested hundreds of new AA batteries, but have NEVER seen one register over 1.58 volts when testing. Either the tester shown in the video is defective because the cell that is good registers 1.65 volts, or the cell was put in a charger prior to testing. I just opened a box of new AA cells, none of them registered over 1.58 volts.

Brin...do you realize how absurd the statement "seein' is believin'...." is today? ANY AND ALL DIGITAL pictures and videos can be gimmicked....no, not gonna sue you....:laughing: If I posted a Youtube video of my cat stating that AA batteries are fully charged when they register 1.56789 volts on a multitmeter, would you accept that as a fact?

Ahh, it is a Harbor Freight multimeter they are using. Could this explain it?

 

[tallyho8]

I guess I have too much time on my hands. I checked a few new Rayovac batteries that I have and they all were 1.64 volts on my trusty Harbor Freight multimeter. I checked some new Duracells and they all checked 1.63 volts.

 

[LD1]

Well, I just checked a new, but about 6month old battery. And got more than 1.58 volts. Thats with 2 good testers. The fluke must round up...

Yes JD....whatever you say I will absolutely believe...You are a fine American and Gentleman and I don't for a minute believe any of the gossip about you to the contrary...

LD1.. your Fluke, is not an electronics tech's meter, it is an electricians meter, and has poor resolution for small DC voltages, Only to 1/10 of a volt, and yes it apparently rounds up to the nearest 1/10. An electrician is more interested in volts, not tenths of a volt, but an electronics tech would want at least hundredths or maybe even one-thousandth of a volt resolution to see small trends when making precise adjustments for instance like a trim pot on a power supply. Of course you already knew this, I was just rambling on here for the benefit of someone who might wonder why.
