Pink new 2600 Samsung 18650s for $2 each, free postage!

Well, I've never done laptop pulls, but I went ahead and bought one. I will do a video of the tear down and results in case anyone wants an FYI and how "not to".

I like this idea, maybe we should do an all in one thread. Name of laptop battery+type of battery inside. Also, show the easiest way to open.

Recipient of two nasty cuts from the devils!

>>>>>Recipient of two nasty cuts from the devils!

My worst cuts from pack-pulling are from the plastic, which is also like razor blades, althought it doesn’t look it. Sharp edges come from packs being slowly peeled off piece by piece with needle nose, or at least that’s what I do. Go at removal too aggressively and the battery covers get marked up, so slow and careful is the way for me. Or REALLY aggressively and even the thin-cell wall can get dented, and that’s a definite no-no. One dent in one of my cells, and it’s in the trash. Too big a chance of puncturing or malforming the catalyst bag. In fact, most li-ion manufacturers say to just plain throw the cell away even if you just drop it.

So I always wear work gloves when pack-pulling. Know it seems like overkill, but it really ends thinking about what is sharp, and allows me to go at it without worrying about cuts. Haven’t had one cut since, and I had a couple almost to the bone from that *&&%$#$ plastic before the gloves.

exactly, i am sitting here with one cut from a NIcd from last night because i didn’t put my gloves on.

Use the cut off saw wheel and start very near seams and it goes better, Gloves are a must.

I usually use a dremmel with a 1/8th” gauard so i know i don’t cut too deep.

>>>>>Use the cut off saw wheel and start very near seams

Yes, I use dremmel cutting wheels, but these acer packs are constructed to torment deconstructors. One seam is easily cut, but the other one is too close to the cells for a cutting wheel, at least it is for me. But I’m pretty fast ripping away with needle nose once I know my hands are protected with those gloves.

On the packs I have right now, an x-acto blade can be fit under most of the seams and cut the glue. On the sides it could be popped open by fitting a screwdriver along the seam and prying up along the direction of the seams--not into the seam towards the batteries. Then the pack almost opens like an oyster, although the amount of glue they put on the cells makes a huge difference. Even so, I still got lots of cuts even after getting the process figured out about as well as I can imagine. Then there's grinding the weld points down, adding solder blobs or brass discs to the positive end if desired, cleaning off all the glue, and replacing torn wrappers. It really sours the value of the deal if you also value your time, but it's great if you have time to kill or have the magic touch that I very much lack when it comes to doing this. Everyone should try one though, ideally while checking initial voltage and internal resistance before pressing those cells into service. It almost makes me feel dumb for buying a bunch of packs with these cells in the past. I was going to sell some of them, and now it's feeling like a burden.

Btw, if you pack pullers are up for it, I'd love to recycle your solder tabs if paying postage is enough to get those mailed instead of going into the trash. Just the silver tabs, not the copper between them. I'm using the nickel tabs for nickel plating as an intermediate layer for copper plating. Or if you're planning to do some electroplating too, you'll definitely want to hold onto those tabs.

I bought one. I’m not really doing it to save money. I just want to see how hard it is - seems like a fun little trial. I plan on using: gloves, screw driver, pliers, solvent, and file.

Screwdriver and needlenose pliers will be all you need for these battery packs getting ready to do an HP pack tonight, I might take some pics

That's a good reason to do it. It's part of the hobby. I just wish I was lucky enough to find free packs like some members here. That would get me way more excited about laptop pack pulls. Free price is best price.

I tell you what, you pay shipping, I will send you the pulls I don’t want.I get 1 or 2 packs free every couple weeks and I only keep pulls that are 2500 or 2600 mah or more.

Hey, I'd be totally up for that, thanks! There was someone else that was willing to do that, I think it was Bigwood, but he's up in Canada and the postal fees were ridiculous. I'll be sure to do some giveaways with those to give back to the forum. I'm overdue for one anyway.

Heat is your friend with glue, if you have a heat gun that is even better provided you do not over do it.
Once you get the glue separating they can open up like a clam.
HTH
Happy hunting!

That sounds much better than my first attempt. My brilliant idea for my first pull was to use an old soldering iron like a hot foam knife. That soldering tip still has plastic I can't get off it, and to add insult to injury, the heat spot welded one of the seams. I'm pretty sure I cut myself on that pull too.

I got my battery. I was able to get all the cells out in under 20 min. There was one casualty.

How smooth does the top and bottom have to be? I got it smoothe enough so that it won’t cut you, but you can still feel the bumps…

I found it to be a very easy process overall if you don’t mind possibly damaging 1 cell. I did not need a solvent to get the dried glue off, it came right off just by scratching it.

Should be fine, you don’t need to take the welds off if you don’t want too. Just make sure the the pieces of metal is flat so you cut yourself

Video of my opening a pack for the first time. Might not help anyone except myself.
