BLF Community Battery Pulls Overview Thread (Laptop packs and Tool Packs)

Thanks Downlinx for doing that.

I know it can be time consuming once everyone is pouring down their data in this thread ;)

anyway, I ordered another pack (same as last time).

and today I bought a Dell pack (they said it was new, but voltage was very very very low) now charging

very very very low? My NOS Sony 2200 were at 2.xxxx volts but charge with capacity very near rating.

Yes, below 1v.

They quickly climbed and after some minutes they were above 3v

Almost finished charging.

Tomorrow I will do a discharge and check capacity, and keep an eye on them.

The price for these are good and they’re listed as genuine and new. Only thing that concerns me is they’re for a model which is very dated now. It’s for an Acer TravelMate 3200 which is from 2004. So these batteries are at beast from around 2005/6? That would make them pretty old. What do you guys think?

9 Sanyo 2400mah? , I think the 8 Samsung 2800mahs are a better deal.

I’ve pulled out packs from laptops released in ’06 and they still show 90%, so I wouldn’t worry too much about age.

Yeh that’s probably the case. I was going to go pickup but realised Kingswood is about 8 days walk from my place.

Were the 2800’s local or internet buy?

Cheers

Australian seller unfortunately. I assure you the US has 100x better laptop deals. You’re not missing out.

I got another pack as my first one, and the same batteries were inside, about the same capacity as well.

The other pack, DELL had about 2000 in them. They were sanyo green tops, called ...xx18650x........I forgot the name.

From Dchomak’s post Here with his permission i posted in this thread and also updated the list.

Just pulled appart a Fujitsu Siemens pack BTP-C1K8 , 11.1v 4400 mAh
It came from a defect lapop, probably main board defect. (wouldn’t turn on)
it contains 6 cells, Sanyo UR18650FJ, they are 2200mAh
The sanyo labeling is very difficult to see at first, the clearly printed info on the cells lead to nothing
All 6 read 3.8v after separating.
Kept 4 out of 6, 2 of them were dented on the side and bottom.

Have them in the Nitcore charger now

This was a new, never been used pack that I was able to tear open with my bare hands. Either I’m turning into a monster or this was an exceptionally easy pack to open. :slight_smile:
All 6 Samsung 26D cells were sitting at 2.9V and are charging now. I have no reason to think that they won’t charge up to just slightly lower than their rated capacity of 2600 mAh.

I love the dell pc764 packs, almost always produce good 2600 or 2550 cells. I will get both of your pulls on the list. Thanks guys.

Last week I got a Dell battery back (here: http://www.amazon.com/gp/product/B000WDRXL4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1)

It had six light-blue/green colored cells in it, no brand name on the wrapper - just a bunch of numbers. Look similar to the LG's in #2 in the OP.

All six tested to 3.88-3.89 volts on my multimeter. I have no means of testing capacity at the moment. I figure the cells have to be pretty new to test with that high of a voltage right?

That is a pack for a Dell not a Dell branded pack. The cells inside could be of lesser quality. I must say the price is right if it is to be used to replace an old worn out pack. There is no sense in spending $100+ for an original replacement for an old laptop that is on it’s way out anyway. It is probably not a good idea to buy these to harvest the cells, for that any NOS (new, old stock) genuine laptop pack from any of the major manufacturers would be better. They can be had for about the same price and will contain name brand quality cells.

The amazon description is all kinds of wrong (says it’s for an Acer?)… the battery pack that arrived was in Dell-branded packaging and the pack itself had a Dell label on it. I figured at $11.xx with Prime shipping, it seemed worth the risk.

That is def. a dell battery, i have torn down a quite a few of that exact model. whether it is an original dell or clone, that i do not know.

I’m new to the site, but I have a bunch of these Philips packs (M4605A) out of medical equipment. They get replaced every 2-3 years regardless of use. They contain 9 CGR18650CG (MH12210) each and were exceptionally easy to pull compared to the drill packs I’ve done. Cadex charger primed the cells and all of them reached at least 90% of the rated capacity. As back up batteries they probably haven’t been cycled at all and arrive at full charge to be recycled.

Thanks guys, list updated
