Tool packs too in this thread or just laptop?

Tool packs are fine, post up, anything we can get batteries from.

For what it is worth, the packs in the batteries for pre-unibody MacBook Pros are LiPo pouches. No pix, I took them to household hazmat long ago.

Toshiba Libretto PA3442U-1BRS P000435740 3400mAH laptop battery yields 18500s which are not very common in packs, but they are unique and useful.

Would be nice to find a good source that was as cheap as the ones that started this thread.

Current price is $17, not bad - but cells in the last pack I received were marginally low on voltage.

from Ubehebe’s post.

!!

Sony has an outstanding white paper for their older Graphite (US18650GR) cells. Not found anything for Pana and Samsung cells.

My i4 is doing initial charge on my NOS Samsung ICR18650-26C laptop pulls. Will switch to iCharger 106b for capacity and IR readings to compare later in the week.

I am hoping to switch aswell.

The GJ114AA battery for the HP HDX 9000 has 9x 2550 mAh Sony US18650GR Batteries. Nice finds at the right price!

Nice thread..

But at the same time, it would be really nice if the top of this thread would have a table with the important info, and maybe a link to the actual post in the thread..this can otherwise become a difficult to navigate thread.

Something like this:

Manufacturer, code battery pack, rating battery pack, cell names inside, cells mAh.

Manufacture code battery pack Rating battery pack Cell name inside cells mAh link to post

Thanks for the idea chibim. When I get some spare time, I will get started on the table. :8)

Go know it's a lot of work!! But once it's done, it's pretty convenient.

I would actually order all packs by Brand name.

Dell with Dell, HP with HP etc.

So it's easy to search.

I want to join, so I just ordered a pack of Amazon Japan.. I think it's new.the laptop that it is used for is already pretty old, so it might be old stock.

Too many cheap No Name brands that I don't want to order..who knows what's inside.

you are quite right, it is hard to find the true brand from the fakes. I can’t wait to see what you get, opening a laptop/tool pack is like a birthday present.

1)Laptop Battery
Dell 6T473

18650 Battery
12x Sanyo Double red 18650 @ 2200Mah

Pulled

New battery pack (probably old stock, because the laptop this one is used in, entered the market a long time ago)

Manufacture code battery pack Rating battery pack Cell name inside cells mAh link to post
Fujitsu FMVNBP135 7.2V 5200mAh Sanyo 2600? link

R1122

pretty low voltage.. the charger didnt want to charge them, so I used my crappy Xtart WP2 (which over charged a few cells)... and it took the cells without hesitation.. after about 10 seconds charging, I whopped them in the Opus, and it charged just fine.

I don`t believe they are bad.. as I think they just got so low from being in stock for a long time..

I am charging them now.

internal resistance... the 4th cell is high..THis was done BEFORE charging.

so I changed the 3rd and 4th cell.. and guess what?

and then I changed cell 1 and 2

I hope I will do it again after the charge, maybe they will have a lower resistance again?? not sure

I`m pretty sure these are 2600... even just looking at the specs. 5200 at 7.2V, and only 4 cells... those must be 2600.

Oh, and the pack was $10..(the seller has more packs, should I buy more?

was that worth it? I hope it was.. but I`m a little bit new to laptop pulls... only done a few Used ones in the past.. and think they were worthless.

hopefully these are okay.

edit: results of discharge

All cells have a resistance value of around 90

Awesome post chibim and I should be able to get started on the table today or Monday. Btw what color top is on you sanyo’s, that should help identify what Mah it is

Sorry no picture but they are light blue.

Light blue is 2600, good pull.
