Which Li-Ion cells from Notebook and Cell Phones

Fetching some information from various threads here and on RC forums it seems obvious that one of the best ways to find cheap and readily avaiable single cell Li-Ions is to rip apart Notebook and Cellphone battery packs especially when those can be found cheap at Surplus stores.

This post/thread is targeted at becoming a reference on which cells can be found in which packs and possibly people finding the right packs in surplus stores or on Ebay will post a short note and URL here then too.

Examples are the 830ma Panasonic 17500´s which could be found in the Qualcomm 820? cell phone packs last year and where sold off real cheap when the phones were discontinued - only to gain in price afterwards when the supply dried up as all the slowflyer guys snatched them up.

I think of most interest for us would be the

17345 (1 x 123 size)
17500 (2 for 3 123s)
17650/17670 for 2 x 123
possibly 18500 for enlarged bodies

The 18650s which are used most often will be hard to fit

TIA for any help / comments

Heres a link with some breakdown of cells used in the Notebook area posted by Koala/Nukiez lately. Notebook packs & LiIon cells

Re: Which Li-Ion cells from Notebook and Cell Phon

I was about to post the Energy-Tek web reference until I saw the link at the bottom. /ubbthreads/images/graemlins/smile.gif

Anyways, I am continuing my search on this. I am sure major battery repacking companies have data on this but they can't be bothered to help out. I have emailed them quite a few times but never a reply. However, if I tell them I've got a dead battery they are always there first. /ubbthreads/images/graemlins/thumbsdown.gif

In my experience of poping cheap laptop packs, most Toshiba and Sony laptop cells are 17670s. Most toshiba cells are Sony manufactured. Don't trust me on this I could be wrong.

Maybe some of you will be interested in a 14500 AA sized Li-Ion.
Go to ebay and look for EN-EL1 ENEL1 Nikon Battery. It should be around the range of 7.4v 800mAh. However, don't be disappointed to see two 650mAh cell when you pop it open.

have fun,
Vince.
 
Re: Which Li-Ion cells from Notebook and Cell Phon

I got two 17500 out of a Sony Floppy Disk Camera pack. I believe it was NP-F330 or something like that.

It was a three finger ***** to get 'em out!!!

I've got an F330 and an F550 laying around....thing is the camera they are for still works, and it's not mine. /ubbthreads/images/graemlins/tongue.gif

Why don't you tell the owner you run a battery recycling facility? /ubbthreads/images/graemlins/naughty.gif

I wouldn't put too much trust in that site. Quite a few mistakes. For example, they list IBM ThinkPad 760 batteries as having (6) 18650's, but if you open one up you will be rewarded with (9) 17500's. Just FYI...

I opened up my IBM 600 Li-Ion battery pack and it has 6@18650's. They are actually 2x3 in parallel to make 2 pairs of 4.2volt x 3= 12.6 volts supply.

Each battery measures 4.2 volt. When the AC power source was unpluged, the DC battery power kicked in. Unfortuanately the battery only lasts 5 minutes.

I wonder if batteries are dying? But when they are fully charged everyone is above 4.2 volt. Is there anyway to tell if the batteries are reaching it end besides runtime test?

Measure the single cells after the Notebook went out - chances are you only have one or two bad cells and the other ones will be just fine. You should be able to detect the "bad" ones through lower voltage as they reach their discharged state earlier.

The owner is my dad and I don't think he'll buy that story... /ubbthreads/images/graemlins/mecry.gif

Thing is he uses it, but rarely....so when he goes to use it, the cells have oxidized from neglect and don't work that well. I've already excercised them once (a sequence of 3-4 cycles) and brought both packs back to life.

Seems the third-party Siemens C25/C28 Li-Ion replacement cells at 1400/1500ma capacity do contain 3 approx AAA sized cells which might/should be 10450 Li-Ions. These C25/C28 packs are available at ~10 USD and at 3 cells and 400/500ma each this would give a nice cheap source for AAA LS mods.

Might just give those a try to check it out

So, if you get 3 packs, and wire them up as 3 sticks of 2 ea, these should fit into a 2D flash, and give you loads of kick? Will the 3 sticks in parallel cooperate with each other if each stick is protected?
 
Re: Which Li-Ion cells from Notebook and Cell Phon

2D flash = 3volts
2x Li-Ion series = 8.4volts

If you understand the voltage, I don't see why not when wired correctly. Remember, a single mistake means an exploding torch. You are actually making a bomb here. Good luck.

I forgot to mention that the "2D Li-Ion stick" will go into an ElektroLumens Blaster VI, which is a Luxeon V, which runs off of 3 x CR123, 6 x AA (using (2) 3toD adapters), or 2 18650, my preferred option right now. However the 18650 are bare cells, and that is a bit troublesome, as I could have the potential of over-discharging them and ruining them. I don't think I will over draw on the current side, but I could deep discharge past 2.5V.
 
Re: Which Li-Ion cells from Notebook and Cell Phon

BTW, does anyone know what kind of cells are in the EN-EL3 battery, or what it's dimensions are so one could make a semi-intelligent guess?

My semi-intelligent guess is that they contain 2 size 18500 cells.
 
Re: Which Li-Ion cells from Notebook and Cell Phon

mark paulus, i think a 5w would give almost no light at 5v, so deep discharge past 2.5v pr cell shouldnt happen?

Could happen if cells differ in capacity. Some cells have discharged over 95% of capacity by the time they reach 3.5V. If the two cells in the pack differ by only 5% in capacity, at 5V total one could be at 3.5 and the other at 1.5. Though most manufacturers recommend discharge termination at values between 2.5 and 3V, I have seen several sources say that the bad stuff doesn't happen until below 2V. One source implies the bad stuff threshold is around 2.3V.
