The Energizer LED Keychain Light, is a small LED flashlight, designed to slip into your pocket or attach to a keychain with the included medium split ring.

It comes in a plastic body (medium greyish-blue in this case), has a 5mm white LED on the end to produce its light, and feeds from a trio of included A76 button cells.

This isn't a "Suuuper-DEE-DOOOOOOper" (as Barney the Purple Toliet Dinosaur might say) flashlight, but it's perfectly adequate for general use, and for showing off that "newfangled" LED technology.

The Energizer LED Keychain Light is ready to use right out of the pack.

Just squeeze and hold the grey button on the upper surface of the product for as long as you need light, and release pressure to turn it off.

There is no continuous or "hands-free" mode available in the Energizer LED Keychain Light; please do not look for or expect to find one.



To change the batteries when necessary, get a small phillips screwdriver (the #1 with a 2.9mm shaft diameter from my set of jeweller's screwdrivers did the trick here), unscrew & remove the two small screws from the underside of the product, carry them outside, and chuck them as vigorously as you can into an open-pit zinc or antimony mine so that bulldozers and such bury them so that they become lost...O WAIT!!! YOU'LL NEED THOSE!!! So just set them aside instead. The screws are fairly small, so I can easily envision them falling into the carpet and later falling prey to the hungry, hungry vaccume cleaner as well as being thrown into a mine.

Using the tip of a knife blade, carefully pry out the used A76 button cells, and dispose of or recycle them as you see fit.

Insert three new A76 button cells into the chambers, orienting each cell so it faces button-end (-) negative down. Be certain that the thin wire loop you see over one of the chambers remains over the top of the cell in that chamber - this is the switch, so this loop needs to remain intact.

Swing the light's halves back together, and insert & gently tighten up those screws, and there, you're finished.
Aren't you glad that you didn't huck those screws into the mine now?

Current usage measures 51.1mA on my DMM's 400mA scale.



The Energizer LED Keychain Light is very small and is made almost entirely out of plastic, so "The Smack Test" would not really be appropiate here.

That said, this flashlight appears quite durable, but I don't believe it is too water-resistant. When I had it apart to do the battery change, I did not see an O-ring between the case halves. When the LED-end was suctioned on, rather extreme leakage was detected. So water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside through the seam that runs all around the outside. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of laboratory rat pee, glasses of milk, slush piles, mud puddles, tubs, root beer floats, tiolet bowls, cisterns, sinks, cups of coffee, fishtanks, dog water dishes, old yucky wet mops, wall-mounted porcelain urinators, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in moderately bad weather.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater, got thrown into a glass of milk, if it fell in a root beer float, if it fell into a bowl of "soft-serv" ice cream, if somebody squirted a Massengill brand post-menstrual disposable douche or a Fleet brand disposable enema at it (and hit it with the douche or the enema), or if somebody or something got "pist off" at it and subsequently "pyst" on it, rinse the parts out with fresh water before setting them out to dry. You don't want your Energizer LED Keychain Light to smell like seaweed, sour milk, flowers, fresh butts, or rotten pee when you go to use it next. Besides, salt (from seawater, disposable douches, disposable enemas, or uranation), lactic acid (from moo juice), glycerol (from antifreeze), or sugar (from root beer & ice cream) can't be very good for the insides.

This appears to be a fairly well-constructed flashlight, provided you don't just beat the devil (or beat the {vulgar term for feces}, or beat the urine, or beat the living tweedle) out of it.
That is, it will definitely do what you purchased it to do - that is, provide light.
