I drilled the hole and need to find a long screw use the power drill to attach to the battery. Thanks for verifying my idea. I needed to find the screw like you used. I liked your drill press.

I’m glad the video helped, thanks for watching

This was very very helpful, GOD bless you for your amazing skills ⭐🔥

[@madcat4563]

Man, I feel like a idiot. I was also at the point of drilling but wondered how to get it out. A screw will help to get a grip on it. Thanks a bunch... my vice will help out a lot.

Thanks so much for watching

[@madcat4563]

@@mr.kongable Ran into a problem.....the battery is really stuck...😬

[@abc-wv4in]

Subbed. My little Thrulight single AAA flashlight has a battery stuck in it. No drill press but at least I know it's okay to drill into the end of a battery. Hope I can get it out some way as that model is no longer sold. Battery was good and the flashlight was used fairly often but it's stuck inside..

[@mr.kongable]

I have a little Thrulight that has a rechargeable battery , it’s super handy but doesn’t have a pocket clip so I don’t use it much. Thanks for subscribing and watching

[@abc-wv4in]

Yes, I have two little AAA Thrulights, one has a keychain attachment and only one light level, but this one has a clip and several light levels. It's the one with the stuck battery and apparently is no longer sold. If I had some way to drill into the battery your video is very clear and helpful. Thanks again. @@mr.kongable

I've got a pen light, a nightcore that has a really nice nichia LED; I use it almost daily. It has two AAA batteries, both were "good" until 2032, it was able to power the flashlight on the first two settings even, but they've corroded inside terribly! I'm pretty annoyed that the batteries both worked and were 9 years from their expiration date, but I'm gonna try your idea in the next day or two to see if I can get the second deeper battery out with a screw. The issue I'm having right now is I don't have any bits that're small enough and 3 inches long that I can get it into the top of the battery since it's a full AAA length inside the tube. Appreciate your video man, you earned a sub! You may've saved me $30 haha.

[@jetjazz05]

Wow. So the update, I've gotta share this lol... I drilled a really long nail completely through the AAA battery, had to put the lip of the tube on top of my vise, hold the end of the screw under the vise with a pair of pliers and HAMMER it, took about 3 minutes, and the screw even stripped out the metal housing on the battery. Luckily it was far enough up the tube I was able to grab it with pliers and get it the rest of the way. Never thought I'd have to work so hard to get a battery out WOW!

[@mr.kongable]

@@jetjazz05 Great Job!!

[@AKing99]

Battery expectations are reference to shelf life in its protective plastic in an ideal environment, dry stable temperatures in the 70o Fahrenheit.

[@AKing99]

Stubborn AA battery was so tight the first 2 screws pulled out making the hole bigger each time. So the 3rd screw (each one a little bigger finally got things moving mm at a time with each blast of WD40! I’m embarrassed so say it took just under 30 minutes but it out and the cleaning begins thanks for the tip 🎉

[@mr.kongable]

@@AKing99 glad it helped!

[@antongorbonosov9065]

Russian, извини но 2 раза пытался посмотреть ролик но не удалось, скажи пожалуйста, а что у него головная часть не откручиваеться, просто когда у меня возникла такая проблема я фонарик разобрал с двух сторон, немного залил уксус подождал и медленно выбил её наружу

[@mr.kongable]

Good job on the use of the vinegar!

[@antongorbonosov9065]

спасибо

[@kerivang8976]

Hot glue another piece of stick to the end of the battery and wait til dry and pull it out...

[@mr.kongable]

That’s a great tip! Thanks

[@mariomarianorocha]

Rapaz, você me salvou, muito obrigado.

[@jozefkrivan3522]

Very you help me solved the same issue, many thanks😊

I’m so glad it helped, thanks for watching!

[@Kevscancave]

I hate when that happens… Them pen lights are great… Until that happens for sure…

[@mr.kongable]

For sure! I love my flashlights and it's such a punch in the gut when one of them is ruined by a bad battery. Thanks for the view!

[@fredcalderon4280]

Awesome thank you !

[@mr.kongable]

Absolutely , glad it helped

[@AshleyAriesK]

Crap,I've got the same darn problem almost. Mine is a skinny little(Coast? Brand)flashlight that's a bit longer than that 1/holds 2 or 3 AA,& the 1 that's stuck is @ the top blocking the others. I think the little metal disk on the neg.side was about to pop off when I was trying to pry it outta

[@mr.kongable]

Can you get to it from the other end? I have a light that both ends screw off and you can see the batteries from both sides but only remove it from one side

[@AshleyAriesK]

@mr.kongable Nope,idk why either..This is the 1st flashlight I've had that I couldn't get the lens/bulb end to open..I was just wondering if that disk pops off,is there more metal under it or what? Someone suggested pouring alcohol,then baking soda down in the cracks around the batt.& trying to keep moving it. Another person mentioned superglue on a nut,then 24hrs.later(or once it's def.set),use pliers on the nut to jostle it out,maybe do the hole in the nut & add screw if ness...Idk,just nervous about drilling into it..

[@mr.kongable]

@@AshleyAriesK I can understand being nervous about drilling into it. I’d try the nut with superglue. Keep me posted, I’m very interested to find out how you did it.

[@pfhastie]

I am trying to remove an 18650 battery that is fully charged. These batteries are known to be dangerous if you pierce them. The flashlight is quite expensive and I don't want it to blow up. Any tips?

[@mr.kongable]

Have you tried putting it in the fridge to get the body of the flash light cold to possibly eliminate any expansion? I am assuming the body of the flashlight is aluminum. That is the first thing I would try, get it cold and see if the battery will come out.

[@pfhastie]

@@mr.kongable Hi there. Thanks so much for responding. The battery is actually in good condition. Freshly charged. It was just a bit tight and I tried to push it in, then dropped it, which pushed it all the way in. I tried putting a screw in some epoxy, but it didn't hold. I'm thinking maybe I didn't wait long enough for it to set so I'm going to try again. These damn annoying little problems!

[@robertbanfelder8283]

Very helpful. Thanks!

[@mr.kongable]

Absolutely!

[@maureenledesma1503]

How did you get out the corrosion?

[@mr.kongable]

I used a piece of sand paper that was rolled into a cylinder

[@nycmaverick]

I have three of these just like this. What causes this?

[@mr.kongable]

To my knowledge , it’s the age of the alkaline batteries, I’ve switched to lithium for flashlights

[@flightofapaullo72]

I was gonna do this, but Google said "don't do it" lol!

[@mr.kongable]

Ha! Well it’s possible, I’d just wear safety gear

[@xmenken1]

The battery company should put mercury alternatives back into batteries and make them more stable. Then they will not leak any more.

[@mr.kongable]

That is one option. The new Lithium batteries are not suppose to leak, so that may be a better option.

[@cphank3722]

I agree the Lithium batteries may be a better option. Corrosion in aluminum flashlights is not the batteries corrosion but the reaction of the alkaline gasses with the aluminum. Aluminum is actually a rather poor metal to use in the presence of alkaline batteries. Soaking in vinegar often helps before attempting removal. Also a dab of Vaseline in the threads when reassembling makes things work smoothly and helps with o rings too .

[@michaelthibault7930]

A preventative measure I'll implement when I remove a very stuck AA in an expensive bit of kit with an aluminum battery holder: I'll coat the interior -- once thoroughly cleaned -- with Anti-Seize grease, leaving only the thinnest possible layer. I happen to have the remnants of a pot of the stuff, and it's now so dried out that it's a thick and gummy paste... (This works with aluminum bicycle seat-posts; the Anti-Seize is applied to the exterior of the post, rather than the interior of the frame.)

[@abc-wv4in]

Thanks. Mine has one regular alkaline AAA battery. I'm going to try the refrigerator tip and if that doesn't help I'll soak the thing in vinegar. At this point I don't have anything to lose as the flashlight is useless unless I can get the battery. out! It seems so tightly in there that I'm not sure any vinegar can get inside, but it's worth a try. @@cphank3722

Yep, sad day

[@mati211p]

@@mr.kongable Never saw swollen eneloop in real life or leak and have them like 200. Something unusual. So bad it couldn't be safely taken out and see the cause (overdischarge?)

[@mr.kongable]

@@mati211p I don't know what the cause was, I have an eneloop charger and I don't put these in a different charger. It's a mystery to me.

а что бы помыть его внутри, используй жидкость для чистки контактов ( жидкая не сухая) или спирт

[@AlphaChimpEnergy]

Rinse it out with some baking soda and water. Let it dry disassembled on your dash or direct sun.

[@mr.kongable]

Good tip! Thanks so much!
