I pulled the nine 17670’s from the battery pack of a Toshiba model 2400-S251 laptop, Part no. PS240U-02S4H7.
i got 16650 from an acer netbook pack.dont recall the model but it had a water drip effect molded in the lid.
and dont worry about being accused of shilling.
this isnt that other forum lol!
This is my very first post, I totally agree with you Dimbo when you mention the culprit of a bad battery in computers are the circuit board, as I have over the years reclaimed so many cells,
for the history , I was first fooling around with Ni Cad from Makita and Dewalt Power Tool,
I used to revive them by specking method using a rasp and 12 volts or 24 volts and making a jig in series where one cell would be treated at a time , so I would drag the last part of the circuit on the rasp using a brass bolt creating a lot of sparks but the batteries were coming back to life as good or better then new in a matter of 2 seconds,
During these early days I even discovered the hidden secrets of Dewalt Chargers
I believe they must have been the very first one to actually have auto sensing relatively high amp chargers but they did not mention that fact, those chargers could auto sense 7.2v 9.6v 12v 14.4v in the early days 16.6v was tops
Any how, they manage to keep this secret for many years until I think Ryobi boasted about such a charger, so every manufacturers when on the ban wagon,
I then move to the Lithium with the advent of the laptop computers and I even found some 26650 in a laptop computer which I still use but did forget which brand and model, having dealt with so many of them,
it is late and I will post later some of the stuff I do with those beyond lighting, hint, my E Bike’s range is 50 miles + 24 volt controller running off a 28volt lithium calculated at 4 volts 7 cell series 4 parallel
You all have a great weekend, I am very pleased to have stumbled upon this Awesome thread.
Ryobi 40V 5Ah pack like Dchomak reported here. I think these are going to start showing up a lot in recycle bins as I have now found another one and dchomak has found like 3. Pack only measured 18V, but every cell was at 4.06-4.07v. Capacity and resistance measurements showed all cells to be in like new condition. Rebuilt into a 5P4S pack for driving a HID spotlight and seconding as a automotive jump starter. Contained 20 Samsung INR180650-13Q's.
Also found one of these 40v slim packs, but haven't broke it down yet:
Yes, I have found 3. Then I actually bought the tool that uses that battery. I got it on clearance, $40.03. (regular price of $160) I made it a point to do that to get the charger for this pack. That charger is $60 separately, plus I got another a new pack and the tool
Of the 3 I found, the first one turned out to be brand new and will charge and discharge at full capacity. I think the reason it was tossed is that there is loose connection of one of the leads that goes to the battery health meter. Sometimes it works and sometimes it doesn’t. I have decided not to risk the repair to the joint as all solder joints a covered with silicone. I may short out something if I try to scrape it away to re-solder. The battery is like new, except I can’t read how full it is. Best to leave well enough alone.
Of the other 2, one will charge and is in perfect health, but will not discharge through the low cutoff circuit. All cells are like new.
The 3rd is toast, all cells are sitting at near zero. I see that a lot in packs in the bin. Sometimes a component on board leaks, taking one or more cells with it.
Can’t wait to see the results of this light. Any light that needs 20! cells has got to be awesome.
This Dyson power pack looks brand new. I found it in the recycle bin. After taking it apart I found that it contained 6 - Sony VTC4’s, (IMR). All cells tested at over 2100mAh. They are rated at 2100mAh. I don’t know why this was tossed. Maybe the onboard BMS board was faulty.
I’m scrapping a 3-year old ASUS ultrabook that bit the dust, and I found it had (2) flat Li-Polys, and the pack was marked as 7.4v 5100 mAh. Trying to think of a good use for those. Maybe build emergency area lights around each one? Anyone try to use these flat cells or have any other good uses in mind?
acer chromebook packs also contain sanyo purple 16650.purple are 4.35v?
I had my first successful laptop pull 
I opened 3 Lenovo L11S6Y01 rated at 10.8V and 4400mAh. The ebay seller said they won’t charge any more in the laptop. That was strange since they are not old at all (manifactured in April 2014). Each of them contained 6 Sanyo UR18650A.
In 2 of the 3 packs all cells had 3.66V. I did a discharge test with my Opus BT-C3100 at 1A and they all hold more than 2300mAh (they have a cut off voltage of 3V but the Opus discharges to 2.8V). All have internal resistance <100mΩ.
In the third pack all cells were at 2.53V. I must have shorted one pair while I took them apart since one pair was at 2.3V suddenly. I gave them a try and they also have more than 2300mAh and less than 100mΩ.
So there was no bad cell in 3 battery packs. Pretty strange…
I got a pretty good score today.
A bunch (8) packs labelled Dell 97Wh Type M5Y0X
Inside each are 9 x 3000mAh cells - some LGABD11865 and some ICR18650-30B
Preparing to do discharge tests. All came out of the packs at 3.8 - 4.2V
Got 2 packs, after prying them open I got 6 samsung icr18650-26c and 6 ‘n18650 t25l l19r1 18073’, what looks like to be DLG’s? Never heard of those, think that they are some Chinese brand. They came out a non-original replacement pack.
The dlg’s where at 2.4/2.7 volts, they are being charged right now. Unfortunately the Samsung’s are around 1.9 volts, I’ll try to charge them carefully, I hope they’ll recover…
Amazingly, after digging into two laptop batteries I had at home, I started looking in the Lowes and Home Depot battery recycling bins and, after about two weeks and four battery packs (and one was completely dead - all 5 batteries were at 0v and wouldn’t even register in a charger) I now have about 25 good working 18650 batteries with probably 15 more waiting in two more 18v battery packs, a double-sized Ryobi and a regular-sized Husky. I’m not even anxious to get to them. I had to get a special plastic container to store them in and since I don’t have any Ryobi or other electric tools I’ve stopped checking in the bins. All due to reading this thread. Thanks.
Just cut my hands and lost an hour prying open dead Asus G73 battery pack. Pulled out 8 LGDBB31865 2600mAh cells. 6 of them at around 0.1V, 2 at 2.884V. HKJ rated them as very good cells back in 2011 with 1.5C max discharge rate, I suppose they are safe to charge?
I’d charge the 2x that came out @2.884v and expect them to have some life left in them, though probably at significantly reduced capacity given the state of the other cells in the pack. I wouldn’t do anything with the others except put them in the nearest electronics recycling bin.
That’s what I had in mind, thanks. Good enough to power some electronics projects I’m planning or LB zoomie.
Some of my battery pulls.
Don’t know from which laptop packs anymore…
On all of them I have used dremmel to clean remains from poles and all double heatshrinked because some had minor damage on heatshrink and I wanted to be safe.
Wrote numbers and capacity (tested by Lii-500) before heatshrinking.
Got this from a friend :)
A lot of testing to do :)

Wow, you have nice friends.
Hey xxxman
When you tear a pack apart write down the manufacture the model 3 and what cells came out of which pack . that was / is still the reason for this thread . the info will possibly be helpful to another member .
Great pic with lots of pretty colors
i see sonys sanyos lg’s ….purplr panasonic 16650’s /17650’s probably from a sony laptop pack( thought it kind of odd to find pannasonic cells in an oem sony laptop pack )
i have a ton of packs that dont work in laptops.
good ones are saved to fix up laptops we get in and refurb.
but these “bad” packs are going to get torn down once we get this big board build done.
btw most packs are built by companies who specialize in such.
i had an oem sony pack that was new but the latches were broke.was built by simplo.had panasonic 3100’s in it.12 of them!
i wish i had the idea to log the info here.talk about a winner!
