Twelve NEW 2400mAh 18650s, under $30?

Hi,

Well, I’ve gone ahead and bought one. Ebay says delivery by 3/11, but I think that I’ve dealt with this seller before, and what I bought got here (VA) faster than that… Will post back.

Jim

Figured it out. Sold by “N&K Trading”… Looks like that is tmart.com, or someone/something associated with with tmart.com.

Bit like these:

Look similar,$47 therabout for twelve so if you pay $40 for the lap pulls its not so good to us in the uk.Thanks marc.

Plus you’d get 6 battery boxes too :)!!

Google finds hits on what appears to be these cells. After some searching, I suspect these are 2200mAh cells… when they were new.

One of the links found a MSDS

No wonder Majicshine cells are so crappy. But for what you paid, and if youre happy with them, thats all that matters.

cat eyes,

What is “BAK”?

comfy chair,

Your pictures didn’t show it, but do these cells have button tops? Or are they flat tops?

Jim

Hi,

The Ebay listing says New Brunswick, NJ, which is probably like across the river from New York:

Incidentally, I’ve bought a lot of stuff Newegg, and that always inevitably ships out of Edison, NJ, which is almost the same place…. coincidence?

Also, before I bought the pack off of Ebay, I did do a brief search of Tmart.com, but that pulled up like 25 pages of results. The one 9600 mAh one I found was $34.99, but it looked slightly different than the pic on Ebay:

Re. flat vs. button top: I looked more closely at the pics from the OP, and those do look like flat tops.

Jim

P.S. On my purchase from Tmart, the payment went to N&K Trading_tmart, thus my “guess” that the ebay seller is tmart.com, or associated with them.

cat eyes,

Who were you talking to/asking?

Jim

Hi,

Oh, ok….

No, I don’t resell lights :).

It’s just that I’ve just gotten interested in lights fairly recently, and there’s a TON of stuff to learn about (for me).

I have a technical background, but it’s been all work, while this is actually FUN, so it’s like “a kid in a candy shop”… and, BTW, I think I’ve mentioned on other threads, my wife is already starting to hate it, because of the pile of lights, batteries, chargers, and rigamarole that I’ve accumulated in the last 1.5 months.

Jim

Haha, yep, same creative spelling in the ebay listing.

Is there good evidence that any cells made in China are automatically 'retreads'? That's not a leading question, I'm truly asking. I know about some of the quality issues, like everybody else I got burned years ago by the Chinese capacitor scandal, but capacitors and batteries are different animals. Lots of circuits still work passably well even when some or all of the capacitors are completely ineffective... for a while, until they vent. Can they really use river water and ox dung in a LiIon cell and have it still work?

I would dearly love to have a tackle box packed full of fifty Panasonic 3400's or Samsung INRs, but not so much I'd be willing to give up food to get them.

These aren't HP packs, they're aftermarket replacements. The genuine HP-branded OEM packs use LG - at least based on the one sample I opened.

edit: The OEM 12-cell pack for the HP DV4 used LG cells... they may use something else for other and/or newer models.

Nearest Home Depot is ~90 miles away... :(

Fenix 18650 has also BAK cell.

They’re $89 now:

but not available in any stores near me :)…

Crude but interesting results...

Solarforce S1100, 3x18650 in series, w/low batt warning that trips at 3.3v/cell. Tailcap draw is 1.22A, current delivered to the emitter is 3.3A.

All cells fresh off the charger, start voltage of 4.21V.

Samsung INR18650 15Q, runtime on HIGH: 1h08m

BAK/CJ 6K00112, runtime on HIGH: 1h30m

comfy,

I’m losing track of this thread. Are the “BAK/CJ” ones you mention above the ones from the $30 laptop battery (the one I just bought :)!)?

Jim

P.S. Are we sure that the BAK/CJ ones are actually manufactured by BAK?

YES.
