[Sold out] 8 Purple Samsung ICR18650-28A $10 shipped

Yeah there are some bulk commercial shipping rates available, doubt they lost money on it.

The shipping cost calculation reminds me how I can order items from China for a dollar or two that includes shipping cost to US.

I’m sure its not that good though, Chinese sellers have it cheaper than our businesses here to send post, which is pretty absurd when you think about it :stuck_out_tongue:

Mine came today came apart easier than I thought it would judging from some of the comments. Next step is to deburr the contacts and clean off the tape and glue. BTW, all the cells measure 3.7 volts. All I can say is "What a freaking good deal!!!"

The same seller has THESE original asus battery packs for sale. Maybe someone could figure out the capacity of these cells for us. Under description 8-cell 63Wh 4400 mAh. Might be worth taking a chance on these for $9 dollars shipped

Its Dremel Time . . . :party:

Still waiting for that last sold battery pack to arrive. Took a bit of time to ship… hmmm maybe he had to source another stack of 163 batteries to fill the last order.

Looks Good… I came so close to hitting the Buy Button for a couple. Still not sure i wont. :weary:

I am not sure how you do the math to figure out which cells are inside. Since they are original packs OEM you can be sure they will be quality japanese or korean batteries.

I guess I will create another post for these new packs I discovered

Seller did not give voltage, but usually 8 cell packs have 2 parallel banks so 2200mAh cells. Maybe less for most of us with our chargers if they are 4.3v cells…

A rule of thumb is to divide the packs rating by 2 if it is 6 or 8 cells, by 3 if 9 cells.

Thanks!

what about a Post where you sum up some Infos about pulling cells from Laptop batteries?
the Math - good manufacturers - how to open them …
maybe a list which cells has been found in which battery
and so on…

:wink:

I got my first pack and already cleaned them up. Dremil the ends and they are all charged. I can only charge them to 4.2v but that’s fine. All the cells seem just fine. Much better deal than the Ultrafire junk that doesn’t last 40mins in my headlamp. These are good solid cells that are worth at least $4-5 each.

I have another pack coming any day. I didn’t need more cells but I’m glad I got them because they are not used like all my other cells. Sometimes I will put in cell in my headlamp and it will cut out before it should. I keep meaning to mark the cells that under preform but I never do. At least I know all my light purple cells are good.

ugh… my fingers cramped from pulling these batteries with brute force

my wife think I have a problem… sheesh what make her like think that? J)

look at the bright side… if I can’t sleep, instead counting sheeps… I’ll count my batteries :bigsmile:

now if only we can find deals on 26650 batteries… :expressionless:

Daylighter I think you might possibly have a problem.

:stuck_out_tongue:

What are your plans for the new stash of cells?

Don’t know yet… actually I still 10 pairs of new ones NCR B and NCR PF from banggood and wallbuys that I still haven’t use yet.
I usually gave my lights away after I’m tired playing with it… I guess this is the kind of batteries that you want to include them with the lights :slight_smile:
I’m planning to build myself a super pack for my bicycle lights for in case of emergency so I could use it for longer run time.
Such as opening Disaster Relief Center where usually there’s no electricity after Disaster struck.
Last year during hurricane Sandy they have to rely heavily on my flashlights to keep the center open at night until Government step in 2 weeks later with the emergency generator :Sp

I got my single solitary pack today. Pulled the cells and 4 of them showed 3.71v and the other 4 showed 3.70v. Lovely. Now I wonder if I should have gotten more. :slight_smile:

Received yesterday. All at 3.7. Great deal!

Correction: Daylighter I think you most certainly do have a problem. :smiley:

The only problem I see here is he doesn’t have enough flashlights :slight_smile:

DayLighter, because these cells are already sitting at the perfect storage voltage of 3.7, I would not charge them up until you actually need them. Cells charged up to 4.2V can loose upwards of 20% capacity (not charge) in 1 year at room temperature, but only about 4% at 3.7.

Other deals that we have come across, where the pulled cells are sitting a little low, I would charge up as soon as possible. For storage purposes, what I don’t know is would it be best to charge them up to 4.2 first and then discharge to 3.7 or only go straight to 3.7. Does anybody know?
