3/9/21 I found out about the recall through this video. Went to Amazon, hit them up on chat, and had the refund available to get a new power bank in about 15 minutes. I was expecting them to say "no" since it has been over 2 years, but they got me sorted with no trouble at all. Thanks Big Guy!
I used to buy computer parts off a guy who would buy computer parts on Amazon and either take the new stuff out and put old, useless parts back in and return it, like taking an X570 motherboard out of the box and replacing it with a M5A97 motherboard and sending it back, or he would just claim they got stolen off his porch. He had been doing it for like 3 years when I last spoke with him back in 2020, he did it multiple times every week, would often do it with $1000-2000 pieces of hardware, and they never denied his refunds or banned his account at all. He's probably still doing it now if I had to guess. It's how he made a living. Amazon really doesn't bother policing their refunds or returns.
My guess for the recall is that as you noticed, the battery was tightly packed inside the plastic case. Li-Ion batteries will expand in their pouches over time. When constrained by the case, as they are here, perhaps over time, the pouches slowly inflated and pushed the case open. Any good design for Li-Ion batteries must allow for a nominal amount of pouch expansion.
I would guess that the plastic housing of the battery bank should allow enough flexibility to expand slightly, or even crack open in the event of a full "puff-up". Pretty much all battery banks have some inherent danger due to the lithium-ion battery pack, so user beware. ;) Since I run a mobile phone repair shop, once I had the unfortunate luck where a phone's internal battery has "exploded" on my work desk (well, caught fire) while trying to remove it. Didn't puncture it as I was peeling out of the housing, apparently it may have had some internal fault (thus the reason for the need of a replacement). From then on I always wear safety glasses when removing glued-in internal batteries. lol
So, my friend had a power bank, what we took apart, and the LiPo battery was so puffed up, that it was around 2 times the size, and the housing expanded with it, even though it was rigid plastic. Nothing is stronger than a LiPo battery puffing up, but a nail.

Seeing the size of those cells and how tightly they're packed, I think I'm going to start leaving my own power bank in a slightly more heatproof location...
You can separate pouch cells from enclosures or each other by dipping a thin but stiff piece of plastic (I use a small RC plane propeller) in lighter fluid and then repeatedly sliding it between the cell and surface. It works perfectly. Those look like nice cells too. I'd definitely want to save them.
Love it. From A Master Machinist to a Master Electrician, you machine as well as I electric. If a screw can go through the hole it's a success. Keep up the Great Vids! And fingers crossed for a Big Clive christmas things from Poundland video.
I don't know if anybody's ever mentioned using dental floss to cut the pad. You can slide down behind and oscillating back and forth to cut the foam or the tape liberating the battery from the device. For those who think there is a better material than dental floss don't you dare try a thin wire. Kevlar fishing line multi strand obviously also works.
A thin wire works fine. If you are going to use it around things that can be shorted out, that means you shouldn't be inside of electronics anyways. And it won't cut into a battery any easier than dental floss, which actually cuts through plastic better than metal wire; since there's more friction. And once you break through into the battery, it doesn't matter if it's string or metal wire, it's going to runaway in both scenarios.
@@littlejackalo5326 Dental floss has more friction than metal? Citation desperately needed. My dental floss is coated in a layer of PTFE, so it's literally coated in a lubricant.

I love when I am so focused on the picture of the circuit and then Clive picks up the actual item and I suddenly remember that I was only looking at a picture.
I spent two decades working in aviation electronics in the US Marines, 76 to 97, and find this very interesting, technology after my own time of investigating, and quite different, substantially more modern. Such minute electronics in my day, were "classified, high end, almost exclusively military", but this is far and away beyond the technology of my time. Thanks for showing all the nitty gritty details.
I was cringing the whole time you were prying to get the battery itself out. Let out an audible sigh of relief. That was terrifying. Amazing thing to watch.
Removes cell and sets to the side. Shorts on loose line of soldering next to arm. Nothing like living on the edge. :) Thank you Clive for everything you do.
I absolutely had tears in my eyes laughing when you gingerly said to the petrol comment " I don't fhhhhukin think soo". One of my jobs as a petrol station assistant is to gently remind mobile phone users while filling up that it is illegal to use a mobile phone on a forcourt. Not because the "radio" side interferes with anything, but because the battery in a phone IS a fire risk and also using a phone is a distraction from filling up a death trap with an equally explosive liquid! Needless to say I have been called a lot of four letter words in my time to which I simply reply, "and you.."
Needed a spudger so went with the same one as you. Works great, has the bonus feature of, if you slip with it, it's great as a makeshift scalpel lol. To be fair any spudger would have done the same I just need to be a bit more careful in future, still the screen has been replaced on the son's tablet so he's happy again.
@@bigclivedotcom yep, it's a skill well worth having. I half-amputated the tip of a thumb many years ago whilst trying to separate some of those lovely sesame brittle biscuits with a flimsy little craft knife. Nowadays I confidently hack tree branches into wooden spoons with razor-sharp whittling knives.
Clive I took the same pack apart and for big solder joints like those I use an old Weller 8200 N 100/150 watt trigger iron takes about 8 seconds of course your mains is 240 something volts but for big joints or things that cant be exposed to heat for long time it seems to be pretty good. Cool video and thats like five things i own that you have disassembled
i repair electronics like this for consumers for a living. For that adhesive you warm it up a bit, and it peels right off, bout 150F. we had a special heating block with clamps for removing batteries and screens.
I had some success with that kind of tape dripping isopropyl alcool and applying a costant pull force and waiting for the glue to separate. What I mean is that instead of constantly increasing the force applied to separate the tape from the other part I just pulled a bit and let the glue separate on its own accord (while keeping it wet with alcool) and then pulling some more etc.
You are correct, Samsung said in a statement to the BBC on 23 January 2017 "According to the findings, the problems centered on insufficient insulation material within the batteries and a design that did not give enough room to safely accommodate the batteries' electrodes."
ElementalMaker I love the mini tesla coil I bought per your suggestion! I’ve since bought a few more diy high voltage kits to play with and building them’s been a lot of fun :)
So a tip for getting through those double-sided foam tape pads is to use dental floss like a cable saw. Easy to thread into tight spaces, and it provides just enough cutting power to get through the adhesive without damaging anything else.
3 year old comment but ill say otherthan isopropal or napthaline, i use a brand name arimid fiber string. for some reason when i say the well known dupont brand name of the polymer it gets hidden on here. really strong fiber, super thin, ultra high abrasion resistance, can cut a limb off a tree with it, 3$ for a roll the size of my head from china lol
I have that exact power bank... and honestly, i moved it from my car to my desk after hearing about the recall. I trust it 99.999% but my fire extinguisher is closer to my desk than my car.
"Not bad for an electrician!" OK, that made me chuckle! If you're going to open destructively you might as well used a fiber wheel on a Dremel or similar -- perhaps doing inside your pie dish!
"They pinched it down so far that they caused a fire issue." Classic Big Clive understatement! lolol I love this guy! Like many other posts, if I saw a BC cert on a product --I'd buy it!!
Try isopropyl alcohol to separate the glue next time. It's what I usually use when removing batteries that are glued in like that, along with your flat case separator. Much safer than prying the plastic. The cells themselves are pretty safe from experience so long as you don't puncture. Even smooshing them hasn't cause me issues so far. Iphones are thankfully still repairable. We can still replace most things in them, though apple does try to make it difficult
12:08 It's fine to desolder those spot-welded tabs - i've removed (or in some cases, needed to "transplant") the little protection-boards from one cell to the other several times, and i've yet to cause any damage. Mind you, i did use quite a chunky tip on a non-chinese-made iron, so there's that too.
I don't understand how something that has been "spot-welded" can be "desoldered". By definition, spot-welding actually melts the material together (hence "weld"), and doesn't use solder at all. In fact, spot-welding is the preferred method of permanently joining to the terminals of lithium cells specifically because it joins the materials with localized heating. This is in contrast to soldering, which requires that both materials be heated up in order for the solder to flow.
@@LicenseToCode Those flimsy nickel(?) strips that come straight out of the lithium cell are spot-welded to those larger tabs. *Those* , in turn, get soldered to the pads on the circuit board. The battery terminals or pads *do not* get spot-welded directly to the circuit board. My guess is, those chunkier tabs get reflowed onto the circuit board, and the nickel strips coming out of the battery subsequently get spot-welded to those pre-soldered metal tabs.
Yeah, his tip was just too small to heat that size joint quickly, typically if you're not melting the solder after 3 seconds, your tip is too small or your heat is too low.
Honest, I saw that video myself, years ago. Some guy claimed to be telling you how to open laptop battery packs. You just pour a little petrol on them and they snap right open! (Yeah, Right)
Use that GooGone stuff to remove stickers and adhesive. It is made specifically for it. Actually, I looked up the MSDS for GooGone and it is a mix of kerosene and heavy naphtha. I prefer to use a light naphtha (Coleman white gas) as it evaporates more quickly and cleanly. I love those zippo lighter fluid bottles because they put out a tiny little stream and you don't use too much. It does work. It works well.
You can use fishing line to cut the adhesive. Loop it around the cell and pull both ends. The fishing line is thin enough to cut the foam center of the double-sided tape
I have one of those batteries, only mine is marked 16,180 mAh. I love it. I use it almost daily and have no idea why they were recalled and discontinued. I really wish I could have bought a second before they pulled them off the market.
On the topic of not taking iPhones apart, I watched a video where a fella bought two new iPhone 12's, took them apart and swapped parts of one into the other. It didn't work, camera was borked, as was facial recognition and the battery indicator insisted that a fake battery had been fitted. When the original parts were refitted, all was good. Even just swapping the camera caused the phone to fail. So all the modules must be keyed to the motherboard, so that's an end to back street iPhone repairers.
“You cant get into iPhones these days” - Lewis Rossmann: “hold my beer” .... Ave: “where’s my mini Bosch chain saw?” - Dave Jones: “We’re in like Flynn” ... ElectroBOOM: “plasma cutter anyone?” The 5 of you guys should do a colab! Would be the best thing ever!
You might try slowly and SLIGHTLY warming the adhesive/plastic case before pulling on the cells/tape/case. I've used a hair dryer set on "warm" and kept far away enough to keep from heating the cells by any appreciable degree. Depending on the adhesive it sometimes can make a major difference in how easy it is to pull off the tape. You also have to make sure the warmth is distributed throughout the item to keep the adhesive from cooling too quickly.
This stuff is really beginning to grind my gears. If one guy can figure out the difference between good and flawed design then why can't we just get products that are properly designed to be efficient, reliable, and safe? Especially when the difference between good and crap seems to be pennies on the dollar even in the worst cases.
Bob Riemersma here is your answer. The all mighty dollar. Companies keep trying to find a way to save an extra cent so as they cut cost stuff turns to crap.
@@Android-ng1wn if they can a good one for the same price as the bad one, then they only make half (or less) of the profits. Why make a good one the sell you once when they can sell you multiple over time because they keep dieing?
Often you can blame Marketing and the bean-counters. If BC is correct and the case was just a tiny bit too small, note that giving it square corners instead of rounded would have fixed it. But no, Marketing says "It needs to be rounded, nobody's buying square stuff this quarter!". The bean-counters get with the insurance people and figure out what the monetary risk is to settle suits or do a recall vs. not making the profit, and recommend not fixing it. So you get 53 fires and a recall.
I believe, the reason for the recall is the battery. Last two years the market has been flooded with Li-Po batteries that, after few months of use, expands without a cause. Very likely this power bank has such a battery inside... Thanks X the video...
Mine stopped working before the recall. When I opened it, it looked like the resistor R19A (at left MOSFET) had burned out. The recall came just handy as by opening I also had broken the case.
I actually messaged Amazon on Twitter in August because they were still advertising the power banks on the site 5 months after they were recalled. They promptly removed the images and links to the dead product pages and thanked me!
"1.6A in current and 1.8A going into battery" Yes, I also suspect of double duty of the inductor. In other words, the NMOS + PMOS + 2x Schottky diodes + inductor probably form a buck-boost converter and the mystery chip likely controls everything operating the all thing in buck mode for battery charging and boost mode when a load is present. It would have been interesting to see the thermal image of the board when one is charging and loading the power bank at the same time.
Charging generally locks out the use of the outputs, as they need to be done exclusively, so the detection circuits can work properly in their respective modes.
Hey Clive! For separating things attached with soft adhesives like double-sided tapes and removing labels I've discovered that a modest temp heat source works nearly every time. Then there are always solvents in heat- sensitive situations . I've used laquor thinner with great success, and ethanol although less effective, rarely affects plastic surfaces.
HG do a product called "sticker remover" that smells properly of turps, not that substitute but actual turpentine. Whatever it is its very good at removing sticky stuff.
I used to work with apprentices in a factory in Aberdeen, Scotland. One day all the apprentices, maintenance and turners, were in the class room doing some basic arithmetic. An electrician apprentice complained that while the turners might be required to work to plus or minus .0015 inches, he only had to work to plus or minus one inch. Big Clive has proven that he can work to much tighter tolerances than that. It was oil field equipment, so all the manufacturing work was done in inches.
I suspect that the double sided tape is supposed to hold the battery from sliding to protect the corners but someone wasnt peeling the backing off before clipping it all together. P.S. On this type of case you are supposed to start in one specific spot (and its never a corner) flex the case as you work your way around, there is no mark to tell you where to start or which direction to go. I ran into a case that is impossible to open unless you grabbed the top and bottom and twisted them slightly back and forth...and then the damn thing just popped open.
I'm not even a tinkering kinda guy nor am I into electronics that much but I could watch this guy tinker and talk for hours if I had to lol the "explosion containment pie dish" hahaha

there is a document i find myself using more and more often These days called the smd codebook and although even that is not knowing what a x1xv is it tells that x1 is either BFT93 or IMX1 or BZX84-C27... xv is most likely a Suffix that not necessarily has to have a meaning other than to differentiate different manufacturers although even that is not always the case
@@TheVitunpaskasaatana mmh that would even be somewhat meaningful as its also a fet but i havent heard of that manufacturer before (not that it would make a difference) while rohm and the like as the codebook suggests are more well known and you probably find a second source for their chip more easily

You can separate pouch cells from enclosures or each other by dipping a thin but stiff piece of plastic (I use a small RC plane propeller) in lighter fluid and then repeatedly sliding it between the cell and surface. It works perfectly. Those look like nice cells too. I'd definitely want to save them.
Love it.

Fellow machinist here, glad to see I'm not the last of us around.
I was a soldering technician in a previous career, the idea of leaving flux residue on the board makes me deeply uncomfortable
Especially after you are trained to wipe your solder with an alcohol wipe and to snip off the end with nail clippers so you get virgin rosin...
Oh, man, you should see the paste soldering they do with microscopes - it'll give you the willies.
@@flowerpt that’s what I used to do ;)
"Peter disposed it my way." - Thank you Peter!
I don't know if anybody's ever mentioned using dental floss to cut the pad. You can slide down behind and oscillating back and forth to cut the foam or the tape liberating the battery from the device. For those who think there is a better material than dental floss don't you dare try a thin wire. Kevlar fishing line multi strand obviously also works.
A thin wire works fine. If you are going to use it around things that can be shorted out, that means you shouldn't be inside of electronics anyways. And it won't cut into a battery any easier than dental floss, which actually cuts through plastic better than metal wire; since there's more friction. And once you break through into the battery, it doesn't matter if it's string or metal wire, it's going to runaway in both scenarios.
@@littlejackalo5326 Dental floss has more friction than metal? Citation desperately needed. My dental floss is coated in a layer of PTFE, so it's literally coated in a lubricant. You are saying a lubricant material (brand name is glide) has more friction than a non lubricant material.

I love when I am so focused on the picture of the circuit and then Clive picks up the actual item and I suddenly remember that I was only looking at a picture.
I spent two decades working in aviation electronics in the US Marines, 76 to 97, and find this very interesting, technology after my own time of investigating, and quite different, substantially more modern. Such minute electronics in my day, were "classified, high end, almost exclusively military", but this is far and away beyond the technology of my time. Thanks for showing all the nitty gritty details.

I'm glad you sold me on those ruideng meters they are very helpful for testing my various usb devices to see what they actually draw.

I absolutely had tears in my eyes laughing when you gingerly said to the petrol comment " I don't fhhhhukin think soo". One of my jobs as a petrol station assistant is to gently remind mobile phone users while filling up that it is illegal to use a mobile phone on a forcourt. Not because the "radio" side interferes with anything, but because the battery in a phone IS a fire risk and also using a phone is a distraction from filling up a death trap with an equally explosive liquid! Needless to say I have been called a lot of four letter words in my time to which I simply reply, "and you.."
These units were recalled because they were just too darned difficult to crack open with a spudger...
Needed a spudger so went with the same one as you. Works great, has the bonus feature of, if you slip with it, it's great as a makeshift scalpel lol. To be fair any spudger would have done the same I just need to be a bit more careful in future, still the screen has been replaced on the son's tablet so he's happy again.

The good part about taking that approach is that your hands don't have to be anywhere near it.
Clive I took the same pack apart and for big solder joints like those I use an old Weller 8200 N 100/150 watt trigger iron takes about 8 seconds of course your mains is 240 something volts but for big joints or things that cant be exposed to heat for long time it seems to be pretty good. Cool video and thats like five things i own that you have disassembled
RUclips at 4AM - Inside a recalled Amazon Basics power bank.
Me: Hmm, what's inside a recalled Amazon Basics power bank.
i repair electronics like this for consumers for a living. For that adhesive you warm it up a bit, and it peels right off, bout 150F. we had a special heating block with clamps for removing batteries and screens.
I had some success with that kind of tape dripping isopropyl alcool and applying a costant pull force and waiting for the glue to separate. What I mean is that instead of constantly increasing the force applied to separate the tape from the other part I just pulled a bit and let the glue separate on its own accord (while keeping it wet with alcool) and then pulling some more etc.

I had one. Loved it but couldn't take the chance so I disposed of it when the recall came through.
So a tip for getting through those double-sided foam tape pads is to use dental floss like a cable saw. Easy to thread into tight spaces, and it provides just enough cutting power to get through the adhesive without damaging anything else.
A light wound g-string for a guitar works pretty good as well.

I have that exact power bank... and honestly, i moved it from my car to my desk after hearing about the recall. I trust it 99.999% but my fire extinguisher is closer to my desk than my car.
Sometimes watching your videos makes me wonder how did you manage to stay alive so far
"Not bad for an electrician!" OK, that made me chuckle! If you're going to open destructively you might as well used a fiber wheel on a Dremel or similar -- perhaps doing inside your pie dish!
You mentioned ABOM79 - love that guy - great machinist !
"They pinched it down so far that they caused a fire issue." Classic Big Clive understatement! lolol I love this guy! Like many other posts, if I saw a BC cert on a product --I'd buy it!!
Try isopropyl alcohol to separate the glue next time. It's what I usually use when removing batteries that are glued in like that, along with your flat case separator. Much safer than prying the plastic.
The cells themselves are pretty safe from experience so long as you don't puncture. Even smooshing them hasn't cause me issues so far.
Iphones are thankfully still repairable. We can still replace most things in them, though apple does try to make it difficult
12:08 It's fine to desolder those spot-welded tabs - i've removed (or in some cases, needed to "transplant") the little protection-boards from one cell to the other several times, and i've yet to cause any damage. Mind you, i did use quite a chunky tip on a non-chinese-made iron, so there's that too.
I don't understand how something that has been "spot-welded" can be "desoldered". By definition, spot-welding actually melts the material together (hence "weld"), and doesn't use solder at all.
In fact, spot-welding is the preferred method of permanently joining to the terminals of lithium cells specifically because it joins the materials with localized heating. This is in contrast to soldering, which requires that both materials be heated up in order for the solder to flow.
@@LicenseToCode Those flimsy nickel(?) strips that come straight out of the lithium cell are spot-welded to those larger tabs. *Those* , in turn, get soldered to the pads on the circuit board. The battery terminals or pads *do not* get spot-welded directly to the circuit board.
My guess is, those chunkier tabs get reflowed onto the circuit board, and the nickel strips coming out of the battery subsequently get spot-welded to those pre-soldered metal tabs.
Yeah, his tip was just too small to heat that size joint quickly, typically if you're not melting the solder after 3 seconds, your tip is too small or your heat is too low.
"Let's pour Petro down the back of a lithium cell" hahahahaha, that made me laugh
Honest, I saw that video myself, years ago. Some guy claimed to be telling you how to open laptop battery packs. You just pour a little petrol on them and they snap right open! (Yeah, Right)
Sounds like a *case* for Darwin...
Even more so if the person attempting such a stunt wedges the power bank between their thighs...
hahahaha his response was great
Use that GooGone stuff to remove stickers and adhesive. It is made specifically for it.
Actually, I looked up the MSDS for GooGone and it is a mix of kerosene and heavy naphtha.
I prefer to use a light naphtha (Coleman white gas) as it evaporates more quickly and cleanly. I love those zippo lighter fluid bottles because they put out a tiny little stream and you don't use too much. It does work. It works well.
I love the fact that the explosion containment pie-dish device is made of conductive metal...
Where's the KABOOM? There is supposed to be an earth shattering KABOOM!
Love that quote.
That's what she said..
You can use fishing line to cut the adhesive. Loop it around the cell and pull both ends. The fishing line is thin enough to cut the foam center of the double-sided tape
Thumbs up for Abom79!
And This Old Tony
I have one of those batteries, only mine is marked 16,180 mAh. I love it. I use it almost daily and have no idea why they were recalled and discontinued. I really wish I could have bought a second before they pulled them off the market.
You don't need to use petrol to release the sticky stuff. Normal isopropyl alcohol works wonders.
yeah, i'm also sure that alcohol would ignite wonders with electrical sparks
@@pierreuntel1970 If it's technical grade, it shouldn't be conductive, and it won't have much water in it... still sketchy as frig though
On the topic of not taking iPhones apart, I watched a video where a fella bought two new iPhone 12's, took them apart and swapped parts of one into the other. It didn't work, camera was borked, as was facial recognition and the battery indicator insisted that a fake battery had been fitted. When the original parts were refitted, all was good. Even just swapping the camera caused the phone to fail.
So all the modules must be keyed to the motherboard, so that's an end to back street iPhone repairers.
It's not a good direction to go.
“You cant get into iPhones these days” - Lewis Rossmann: “hold my beer” .... Ave: “where’s my mini Bosch chain saw?” - Dave Jones: “We’re in like Flynn” ... ElectroBOOM: “plasma cutter anyone?” The 5 of you guys should do a colab! Would be the best thing ever!
You might try slowly and SLIGHTLY warming the adhesive/plastic case before pulling on the cells/tape/case. I've used a hair dryer set on "warm" and kept far away enough to keep from heating the cells by any appreciable degree. Depending on the adhesive it sometimes can make a major difference in how easy it is to pull off the tape. You also have to make sure the warmth is distributed throughout the item to keep the adhesive from cooling too quickly.
This stuff is really beginning to grind my gears. If one guy can figure out the difference between good and flawed design then why can't we just get products that are properly designed to be efficient, reliable, and safe? Especially when the difference between good and crap seems to be pennies on the dollar even in the worst cases.
Bob Riemersma here is your answer. The all mighty dollar. Companies keep trying to find a way to save an extra cent so as they cut cost stuff turns to crap.
@@Android-ng1wn if they can a good one for the same price as the bad one, then they only make half (or less) of the profits. Why make a good one the sell you once when they can sell you multiple over time because they keep dieing?
In this case he couldn't figure it out and was mostly guessing around. I was expecting more.
Often you can blame Marketing and the bean-counters. If BC is correct and the case was just a tiny bit too small, note that giving it square corners instead of rounded would have fixed it. But no, Marketing says "It needs to be rounded, nobody's buying square stuff this quarter!". The bean-counters get with the insurance people and figure out what the monetary risk is to settle suits or do a recall vs. not making the profit, and recommend not fixing it.
So you get 53 fires and a recall.
I believe, the reason for the recall is the battery.
Last two years the market has been flooded with Li-Po batteries that, after few months of use, expands without a cause. Very likely this power bank has such a battery inside...
Thanks X the video...
Mine stopped working before the recall. When I opened it, it looked like the resistor R19A (at left MOSFET) had burned out. The recall came just handy as by opening I also had broken the case.
I actually messaged Amazon on Twitter in August because they were still advertising the power banks on the site 5 months after they were recalled. They promptly removed the images and links to the dead product pages and thanked me!
"1.6A in current and 1.8A going into battery"
Yes, I also suspect of double duty of the inductor.
In other words, the NMOS + PMOS + 2x Schottky diodes + inductor probably form a buck-boost converter and the mystery chip likely controls everything operating the all thing in buck mode for battery charging and boost mode when a load is present.
It would have been interesting to see the thermal image of the board when one is charging and loading the power bank at the same time.
Charging generally locks out the use of the outputs, as they need to be done exclusively, so the detection circuits can work properly in their respective modes.
I still have one of these. Been using it for 4 to 5 years at least. No idea there was a safety issue.

Hey Clive! For separating things attached with soft adhesives like double-sided tapes and removing labels I've discovered that a modest temp heat source works nearly every time. Then there are always solvents in heat- sensitive situations . I've used laquor thinner with great success, and ethanol although less effective, rarely affects plastic surfaces.
HG do a product called "sticker remover" that smells properly of turps, not that substitute but actual turpentine. Whatever it is its very good at removing sticky stuff.
When it comes to pouring gasoline onto a fully charged lithium cell to release the adhesive, I’m with Clive - “I don’t think so!”.
Incorrect quote. Actually, "I don't f**ckin' think so". Accuracy when quoting is important. I used asterisks because this is a family site.
@@pmpwiz This is not a family site.
I used to work with apprentices in a factory in Aberdeen, Scotland. One day all the apprentices, maintenance and turners, were in the class room doing some basic arithmetic. An electrician apprentice complained that while the turners might be required to work to plus or minus .0015 inches, he only had to work to plus or minus one inch. Big Clive has proven that he can work to much tighter tolerances than that. It was oil field equipment, so all the manufacturing work was done in inches.
I suspect that the double sided tape is supposed to hold the battery from sliding to protect the corners but someone wasnt peeling the backing off before clipping it all together.
P.S.
On this type of case you are supposed to start in one specific spot (and its never a corner) flex the case as you work your way around, there is no mark to tell you where to start or which direction to go.
I ran into a case that is impossible to open unless you grabbed the top and bottom and twisted them slightly back and forth...and then the damn thing just popped open.
I'm not even a tinkering kinda guy nor am I into electronics that much but I could watch this guy tinker and talk for hours if I had to lol
