Can I drill a hole in a stuck battery?

I have a zebra light sc600ii with an lg 18650 stick in in. Happened before but was able to shake it out. No luck this time. I cut the wrapper and folded it up in sections and tried pulling the battery out with a pair of pliers. All the pieces broke off. The cell is fully charged and if I screw the cap on the light does not come on. This light has the pins on the cap not a spring and I think the cell is too long for this light

Any help appreciated

Don’t drill it! Very dangerous.

You might try a really strong magnet to help coax it out.

Not a good situation! Is the battery a button top? I would not drill a hole in the battery if you can avoid it. Have you tried to put the flashlight in the freezer for awhile and then try to shake it out? Or maybe put some silicone between the battery and the flashlight tube?

I’d rather use my flashlight around the house than turn on the lights.

Turn ON the light to drain the cell first, then it will be safe to drill a small hole and use a slide hammer with a screw attachment to yank that thang out of there.

Now i used to think that i was cool,
drivin' around on fossil fuel,
until i saw what i was doin',
was drivin' down the road to ruin. --JT

Sorry to hear this.  The freezer idea sounds like it might work.  Hope you get it out.  If you do, I would advise not putting that brand cell in the light again.

I would use epoxy or jb weld to glue something like a wooden dowel to it and then try to pull it out.

Find a way to attach a paracord or some heavy string on the other end a swing it in circles really hard to centrifuge it out.

> Happened before

stop doing that! Facepalm

post a video on youtube, and send zebralight the link

ask zebralight whether they want you to send them the light

of if they want to just ship you something else in stock, based on the video alone

hurry
they might be going out of business Cash

Some good, and maybe not so good suggestions, thanks! I think I’ll try the jb weld first

The freezer idea sounds good.

Make sure it’s clean and everything before you jbweld. Or if you know someone with a tack welder, you could just tack a bundle of nickel strips in there to pull on.

Definitely epoxy and a popsicle stick.

I think I would try making a loop at one end of some 12/14 gauge wire and solder it to the top of the battery, and then try to pull the battery out that way.

Biggest issue here is going to be that he’s only got access to the bottom of the battery because the light is a unibody design. I agree with the epoxy ideas. Maybe freezer and epoxy. I’d see if you can drain the cell by connecting the negative end to the body of the light and leaving it on, just in case anything unfortunate happens.

If this ever happens with alkalines, though, feel free. It’s a bit messy but there’s no fire danger.

Yeah combination of freezer and epoxy sounds like the best idea. Good luck.

Soldering could work if the iron tip was blunted with enough solder dangling at the tip to transfer heat to the battery terminal quickly. You wouldn’t want to be waiting around heating up the whole cell.

Soldering to cells isn’t a great idea, but to quote diode gone wild, “it’s not the best idea, but it works”

The key is a powerful iron and getting it done quickly.

Will the battery shrink more than the tube in the freezer? Why?

Hummm super glue ads state that 9 drops will bond enough to lift a 5 ton car. So maybe give that a try?

Yeah but probably not bonding to metal.
Oh for bonus points, scratching the metal a bit with something (sandpaper, but idk if you can get to it easily?) should help with adhesion.

I have successfully removed stuck batteries by taping the light to the end of a broomstick perpendicularly to the the broomstick and slamming the stick against a table or something. The broomstick and light come to a stop but the battery keeps going.

Yup — whatever you try, don’t drill a hole in the battery!

Freezing will shrink the alu tube and hold the battery even tighter, it will shrink 3x for every 2x of the steel battery.

Maybe carefully heat it then? I would assume it should expand 3x for every 2x also correct?

al gets hot lot faster than steel, so the AL tube will expand sooner than steel battery will. but i still would not do it, temp needed to expand the tube enough will heat the battery above safe temp.

put a bit of wd40 between the cell and tube walls, let it sit, then swing it hard, as you would mercury thermometer, it may get the cell out.

Maybe best of both worlds. Leaving it a night in the freezer. And then holding it in your hand.
In bare hands is perhaps a bit too much, in that case I would suggest a pre-heated oven mitten.
Assuming that the alu on the outside will get warm faster than (the cold core of) the battery.
Tapping from time to time. On a piece of wood, if the battery does not protrude from the body.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

is it a protected cell with a pcb on the negative side? if so solder something to the negative end, and pull on it, even if it s not protected, solder anyway, it’ll destroy the cell, most likely but it’ll be out
