A family member accidentally left their 3aa Mag Led on, and the batteries completely drained. Now the last battery is stuck. Any suggestions on how to remove it?

Thanks
 
Just a shot in the dark here, since I haven't ever attempted what I'm recommending, but...

#2 pencil and a drop of super-glue? Drop of glue on the eraser, carefully slide it down the barrel until contact with the battery, hold it for a moment or so, see if it has enough traction on the end of the cell?

I dunno, just kinda popped in there...

Also, centripidal force approach-

A couple feet of string, tied/taped/attached to the head end, probably as close to the bezel as possible, go outside and carefully spin the hell out of the light. Be warned, the AA cell is probably going to have pretty good velocity if it does get free.

Anyways, hope this helps.

Q: Does a battery expand when used? Is it the gases inside that is generated from the chemical reaction?
 
Try spraying in some WD40 (or similar) then wait a while so the WD40 can get where it's needed and softly bounce the flashlight on a hard surface (tail cap down of course)

Slide the light into a piece of PVC long enough to support the head and extend beyond the tailcap. Remove the tailcap, and use the flashlight/sleeve as an impact hammer on a wood surface.

not that I know of, at least not for alkaline [yeah it'll expand, but thats under some serious heat, not under normal usage unless theres a short]
Typical reasons why a battery would get stuck is from the leaking of the electrolyte [Manganese Dioxide paste :thinking:]. Most name brand cells, should it leak it usually leaks from the cylinder head [crimped area] but some leaks directly from the side [incorrect/inadequate envelope sealing] and once the electrolyte reaches air, it crystallizes into this yellowish-white stuff that works better than glue in some places...I think this may be the cause of what appears to be the cell expanding
 
used to happen all the time in my mag's, funny it never really happened in anything but a 2AA mag or solitaire... I usually just banged it until it came out... Can you remove the head, led and switch assembly as you could with the older ones? I'd just stick a pencil and jam it down if you can. The WD40 route is also a good route.
 
Fix a leaked M@g can be easy. Remove the head, remove the switch assembly, remove the tailcap. Use a plastic pipe to push the batteries outside the flashlight barrel.

1. If the tailcap refuses to unscrew, use a can opener.
2. To remove the switch assembly, you need an Allen key. Then you remove it by pulling it from the top.
3. If the batteries are stubbornly stuck inside the barrell, soak it in winegar overnight.

The inside anodize of flashlight barrell will be totally ruined from the battery leakage. It doesnt' affect the flashlight operation, anyway. I used to re-paint the inside of the barrell with black acrilyc lacquer.

Hope this helps

For what it's worth, warranty is going to replace it.
