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

Dewalt 4.0 Ah 18 V packs contain 10 pieces of Samsung 20R batteries (green color) 2000mAh.

I've ordered 10 of those & will update when they arrive, relisted here: http://www.ebay.com/itm/141355585144

That's the same seller that had another batch of different ones a while back, can't remember if they were the Panasonic 2900s or Samsung 28As...

The white ones were Samsung –28A cells.

Also, a Dell PT434 battery comes apart fairly easily. Had one for my ‘gaming’ [it will run WoT on low graphics, and RCT3 @ max cleanly] laptop that wouldn’t hold a charge, popped it apart and the six 2550mA USGR’s inside tested between 3.7 and 3.8v.

Playing battery roulette at the flea market...

Samsung ICR18650-28A

Thanks for doing this! It’s a huge help.

26F/26C and 28A have about the same capacity when both are charged to 4.2v, is there any data on whether the 28A will have a longer service life than 26F/C when used under the same conditions?

Lenovo branded 42T4690 (11.1v 3900mAh 44Wh) --> 6x Panasonic Prismatic CGA103450A @ 1950mAh (1x 0.00v 2x 2.2v 1x 2.6v 2x 2.7v)

These, according to the series name in this datasheet, are LiCo cells, which might make me look like an idiot for doing this.
some info from Keeppower about these

I got some of these from a Toshiba laptop about a month ago.

Any circa 2011+ ultrabook will most likely carry cells like these in their packs. Too bad there's no host to accommodate them :P

I am still working on getting you guys updated in the spread sheet. Some have been updated and will try to get the rest tomorrow and tonight

A Li-ion powered [pistol grip] spotlight? Dremel-out the peaks in a SRK battery tube and put a coupleafew of those in? A test-bench for driver and LED tuning?

Thanks, I’ve never seen those before. Interesting alternative to the pouch-cells that Apple seems to have switched over to.

What is the problem charging them in that charger? The datasheet lists 3.7V nominal, 4.2 charge termination.

Would the thread be somehow less informative if the updates were placed in the first post instead of the second?

I have bee tossing around that idea for a couple days now. When I get a chance I will switch them around. I wish I could add another editor to the spreadsheet post.

The change could better for some. When I open a thread it is only the new posts and in reverse order (except for the original post (post zero). So it is better if the original post is an intro or is packed with info/links and not packed with large images. This also reduces the download streaming requirement at my end - and on the website.

You can try throwing it up on a google docs spreadsheet with public edit and link to it in the OP (iframe embed doesn't work)

And probably try what I've been doing and have all the images in an album like on imgur/flickr or some sort.

I guess its a pretty unconventional look, seeing these cells in a charger that doesn't have the 103450 size in their supported list :P.

I went ahead and switched the 0 post and the #1 post, tell me if you guys like this better.

Nice! :smiley:

One cell was slightly scraped during removal and the metal beneath the casing is exposed. If I wrap it in packing tape would that render it safe for use?
