QTEATAK5Pcs 2X 1.5V AA Battery Holder Case with On/Off Switch and Wire Leads

Nice project AA boxes. I use them to convert some Smartthings devices from CR-2050 batteries to AA. The CR-2050 Batteries in the Smartthings devices would last 4-6 months. I've converted most devices to AA batteries using this battery box and the AAs are going on over 2 years and still working. I used the first ones I bought before so I bought some more. I guess the downside is the big black box. But they don't bother me.

These came very fast and work fine. Unfortunely, I bought the wrong kind. They were for a toy of my grandson's and found out I really just needed a AA battery holder with only one battery, only 1.5 v. was needed not the two cell holder, 3.0 v that I ordered.I'll keep them and maybe find another use for them. I did like the fact they each had a switch to turn on and off the voltage.

The media could not be loaded.  Used these to make some LED signs powered by double a batteries. They are very handy, but had a little trouble with the backs not staying on.

Used to replace a broken battery box on a cap-mounted headlamp, and works just fine.I disassembled both new and old, soldered into the new, eliminating the switch, and all is good.The old has a switch on the lamp head itself, making the switch in this box redundant,with space from the removed switch allowing me to secure the wires of the old.Strapped onto the back of a baseball cap's rear adjustment band with Velcro, it's enabled me to revive a years-old 2-AA LED headlamp I've been using for a long time.Quality seems a bit sketchy so far, as it seems rather flimsy. But given that it's sold as a five-pack, I can see me rockin' my headlamp for many years to come. I've been using the first of five boxes for roughly a month of intermittent use, and it's done well so far.2-AA headlamps seem to have been a rare commodity since Day One, so if you can find a good one, I strongly encourage you to grab it. Mine is lamp only, no varying 'modes' of flashing, no 3-AAA, no other lights. Mostly we must suffer multiple modes and beams, odd batteries, too many batteries,crazy modes of S-O-S and such, just before we can get to a simple light to lead the way.I'm gonna hang on to the simple one I've got for those very reasons. I just want the light.

I use these for powering strings of mini LED's, and they work great. I gave four stars for easy to remove because there is a little screw that secures the battery compartment, but it seems to stay closed just fine without it if you choose to leave it out for easier access.....I would buy them again.

They work but very low quality.

Never dreamed that this part would be available. Nothing fancy, but it filled the bill for my simple fix.

Very easy to work with, solid construction
