Product Description
Home Diagnosis
Don’t waste time battery swapping when a device fails. With this instant-read tester, you’ll know if your batteries are the problem right
away. The sturdy, compact device requires no batteries of its own to operate, so it’s always ready to perform. The simple, color-coded analog display needle is easy to read, so you’ll have no need to dig out the operating manual to translate the results.
Battery Testing Tips
You can test rechargeable batteries or standard alkaline with the BT-168 battery tester. Be aware that rechargeable batteries are a little lower voltage (1.2V) even fully charged compared to alkaline batteries (1.5V).
They’ll operate well even when reading yellow or on the low end of green. When testing, always make sure the negative terminal is positioned near the T-arm on the device. Button batteries will indicate the negative end.

We all have batteries lying around the house, sometimes they appear in random places, on a countertop, under a couch cushion, or in a kitchen junk drawer (surely there’s SOME life left to it, right? I mean, why else would someone have thrown it in there??). Here is a simple test that you can do yourself to test if your battery still has some life left to it . . .
This works on the following size batteries: A, AA, AAA, C, D
Stand the battery up on the negative end (the flat end).
Pick it up about 3/4 of an inch off a solid flat surface.
Drop it. If it lands with a small thud back on the flat end and stays in place, the battery still has a charge.
If it bounces and then falls over, the battery is dead.
Still unsure of what it’s supposed to look like? Here’s a Video that will show you:

(Please note, the Dead battery in the video did have a “charge” of .71 (less than the amount needed to power a mini flashlight and was indeed, dead.)
When Discarding a battery, place a small piece of tape over each end to help prevent possible fire.
9 Volt batteries can be tested by wetting your finger and laying it across the top of both posts (positive and negative) if you get a Tingle- it’s LIVE. If you don’t feel anything, it’s dead. Please note, the “Tingle” can be pretty strong and shouldn’t be attempted by those with heart conditions or pacemakers. (That’s my disclaimer right there!)
Never store a 9 volt battery in a junk drawer where it can come into contact with a metal object such as a paper clip, steel wool, etc as this
can cause items to ignite and create a fire in your home.
If you don’t believe me, put a 9 volt battery in your pants pocket with some loose change and you’ll feel the heat in short order… we could even call you Hot Pants! Always dispose of batteries by placing electrical tape over the tops of the positive and negative posts.

We all run into a situation when batteries in our remotes, toys, keyboards/mice run out. If we don't know how to check a battery we might throw out a perfectly fine battery (especially when we have a pile of them somewhere in the drawer). This electronics tip has to deal with checking common alkaline AA/AAA batteries or AA/AAA rechargeable
batteries for proper voltage with a voltmeter. Disclaimer : some people might say that a battery should always be tested under load but I have found that in most common household applications this is insignificant and will not change the results of the testing too much. Things that you will need : Basic facts : To test the battery, turn on your voltmeter, put the voltmeter on DCV and make sure that it is far above the battery voltage, on most voltmeters there is a setting "20" in the DCV area, so switch your voltmeter to that setting. With the battery in front of you, put the red probe to battery's nipple (+) and the black probe to the battery's flat side (-). Notice the voltage reading on the voltmeter. If the reading is more than 1.3V for alkaline battery
(not rechargeable battery) then the battery still has some juice left in it, don't throw it away. Otherwise, properly discard of the battery. Tip : do not use old and new batteries in the same device at the same time. Try to use batteries that have same amount of energy stored in them. Another tip: I sort my batteries according to Voltages, 1.35+ Good, 1.2V-1.3V Ok (but almost out), 1V-1.2V Discard. I will attach some pictures of measurements in action. Instructions
