Hello :cool:

My well know supplier for batteries has now in stock large qty of Samsung ICR18650-28A rated at 2800mAH. I already bought from him ICR18650-26C (2600MAH) and I'm very pleased with it.
googling this new reference I found one interesting link :
www.hp.com/hpinfo/globalcitizenship/environment/productdata/pdf/ba_sdili-ion2800_us_eng_v1.pdf

So it seems that this new model really exists. Now I'm wondering if some cpf member already got this 2800MAH battery and what he thinks about it.

Thx

Well could not resist... put the trigger on 4pcs... it will arrive in 2 days :naughty:

The vendor is from Shanghai and he's an official distributor of PANASONIC, LG and SAMSUNG cells.

If a respectable cpf member want to test one and will publish capacity number and discharge graphs, I can send it for review :grin2:
 
Any feedback yet on these new batteries? I'm in the market for a good high capacity 18650...

I received the cells yesterday:



Seems good so far. Put one in CL1H 3SD Q5 and got 1 hour 44 min runtime on high. Compared to 1 hour 25 min with AW2200, I think it's a valuable improvement :cool:

Will send one pc to Silverfox for more scientific review. :popcorn:


Regarding the Pana 2900mah, well it's very difficult to source. My supplier told me that all production is reserved for high-end laptops and the few ones we see on ebay for example are grade B or C stuff rejected by battery manufacturers... So it's better to stay away from it. The Samsung are finally the best choice right now.
 
Soooo, how can we get some of these? How much were they? I am assuming they are bare cells, with no protection circuit. Are they flat or buttontop?
 
I think they are without protection circuit (someone can confirm ? :candle:) but I really don't care because all my lights have under voltage protection...

Otherwise, they are flat (no button top). well I mean they have a button but it's aligned on the top (is it clear ?)

To get some, I can give the supplier by PM but he's in Shanghai (China), he doesn't speak English and I don't know if he does export :thinking:
 
no protection circuit.

interesting. my old samsung cells are green.

China, from what I know, cant export li-ions.

Hmm looks like China exports a lot of li-ions. I did hear about a short term limit on shipment by air that was related to safety/security concerns during the Olympics. I would assume that ban has passed.
 
these 2800mah work fine so far. I will send today one piece to Silverfox for testing. expect a review soon...

It looks like that LG has also 2800mAh 18650 batteries - ICR18650C1

And there are some auctions on taobao that are offering Samsung ICR18650-30A (3000mAh) batteries.

Strange thing is that is impossible to find some information about these high capacity batteries on the internet :(

be careful. they are even more fakes on taobao than on ebay ! :shakehead
and these 3000mah samsung are definitively fakes (I've got confirmation from official sansumg distributor).


From EMS tracking, the 2800mah cell I've send to silverfox is passing now the US customs. He should get it this week.
