Do you hate it when the batteries rattle?

I sure do. If I have a light with a loose-fitting battery I'll wrap paper around the battery until it's silent.

My NiteCores though, they have tough enough springs that I haven't needed to.

Rattling doesn't bother me. Potential for intermittent contact between fuel cells does though.

Not really, unless it causes mode jumping.
P

the rattle doesn't bother me, it's the whining noise that bothers me.

What I hate more than Rattles,

is when I buy a dozen protected Li-Ion cells,
and 3 or 4 of 'em simply WON'T FIT
into one or more of my flashlights !
< sigh >


So then I've gotta' MARK then somehow,
and take Great Care to AVOID an awkward situation !

If batteries rattle I'll wrap some aluminum foil around them for a more snug fit.

Kamagong- I truly hope you're kidding about the aluminum foil... If you're serious, you've been blessed so far in not having a shorting issue result in a runaway cell... Not second guessing what may work for you, just HOLY COW you've been lucky...

Yeah, I hate the rattling - but (like bykfixer) not quite as much as potential movement involving electrical connections not really optimized for that. That often doesn't end well. I've never dealt with it for long though, as I've always quickly applied 1/2/3 turns / wraps of 1" masking tape to the cells I use in such lights. I don't consider masking tape good for many things besides masking, but this is one of them. Nice and non-conductive too.

A friend of mine reccomended wrapping a section of auto wire loom wrap with electrical tape for an inexpensive space filling sleeve.
One of these days I'll try that.

Kamagong, did you see this? Really important info.

Delrin Battery Sleeves...
for CR123'a in an 18650 tube or AA's in a CR123 tube.

I usually have not experienced 18650 tubes too large for 18650 batteries to rattle. It's usually the opposite. The newer18650 cells don't fit the older 18650 tubes.

I had no idea. Can you explain exactly what happens and why this is so dangerous? Thanks.​

Using aluminum foil in the battery tube creates the risk of short-circuit. With lithium batteries this can lead to extremely hot fires, explosions and release of toxic gases that can cause severe permanent health problems.

For your own safety, ditch the aluminum and use paper to keep your batteries secured.

I never knew that it increased the risk of short circuits.

I cut one of those plastic sleeves you put pages in that go in a binder to size. Works really well and stays in the battery tube.

[ knock on wood ] I've yet to experience this - but it would bother me I'd think.

I actually like when they rattle. I don't know what it is. But I do like it.

Aluminium is a metal! And thus alu foil too... It's like putting loose batteries together with keys in your pocket.

+1. I use rubber sheet cut from an old bicycle inner tube. Rolled 2 layers thick to fit an 18650 in a 21700 / 3x AAA sized tube. Another piece to fit a 16340 in 18350 tube without rattling. Small rubber bands, O-rings or a correctly sized piece of PVC pipe would work too. Who needs ready-made adapter from eBay when a piece of junk does the job?

That's quite a bit of shimming @RetroTechie. I have one 2c light that I had to wrap one layer of paper around the batteries for a perfect non-rattle fit, but I wouldn't want to deal with a shim that was rubber. Does it stay in place or do you have to remove it each time you change batteries?

Hey guys, these are the answer...

I keep a big stack of them on hand always as they are good for several uses. Just keep adding layers until you reach your desired thickness.
