AA Cells

[SocksWthSandals]

Hey all,

Going to be getting a new light with the AA body and was going to be going with the Hive driver and I was thinking Nichia led.

I have a few vapcell gold 14500 cells. Don had suggested protected cells for the charging/discharging so I was searching around for something good.

What do you guys carry in your lights? Im unsure on what to look for voltage/current wise. I would assume with the Hive I will need something with a higher voltage. and I was thinking of getting this little guy?

I do have a crap ton of these laying around, are these ever good in a pinch even though they are only 1.5v?

Update - These KeepPower ones dont seem to really fit with the Hive and the AA body. the top button of the battery kind of got a bit smashed.

Cell completely broken already? Can unscrew the switches and cut off 1-2 turns of the spring, then there will be a little more space, but then maybe standard AAs will have poor contact, or not, I don't know. Is it possible to measure the real length of these 14500 and standard AA with a caliper? pre-closing 1 of the contacts with adhesive tape or electrical tape

Those Keeppowers are 52mm long which puts them two-three millimeters longer than most AAs and 14500s. I have several of them and they work great, but the additional length is a problem using them in several lights. They work best in lights that have springs at both ends as those tend to be more tolerant of longer cells.

Not broken, just a little dent in the top button that makes you go "yea probably shouldnt use this little guy"

As long as it doesn't break the protection board, if it's in "+" then it's not a problem. I have a few crumpled 18650s and they work great. If you could made pictures "+" it would be cool

This is what the cell looks like after a few minutes in the light. I just don't want to damage the cell or the driver.it may just be a tad too long. The unprotected vapcells fit great though!

Thank you, i see, now the easiest way here is to cut off part of the spring at the switch. I see about 4 turns in it, if you cut off half, then with full compression in the flashlight, a place will be freed up just so that there is a clamp and the battery does not deform. If the pressure still seems too strong, then you can still cut off a piece from the coils until action it feels good. I had the same with Mac's Tri EDC, half of the spring was already cut off and it worked well with a protected 18350, but with an unprotected 18350, the contact was unstable, stretched the spring a little and it began to work perfectly with all batteries.
