10ah 18650 cells

[Whales]

Inflation is spiralling out of control.  We need to re-issue batteries with new units like kmAh to make them convenient again.

seen some 10000mah lithium ion 18650 calls on ali,anyone tried any?

Yeah, to my shame I drunk-ordered 4 of those 10000mA/h cells out of curiosity. They weigh 22g, whilst my 2200mA/h cells weigh around 48g. From fully charged (4.2V) to empty (2.8V) at 100mA discharge rate, I measured them to be 350mA/h!!!!

It is a shame that the fake market makes shopping for "real" 18650 cells practically impossible.  The 18650's are so convenient for small flash light and little electronic gadgets that one can cook up.

With the more modern (slim) laptops, they already moved away from using 18650's.  So even the re-packed/re-skined battery market will have a sourcing problem.  I suppose consumer 18650 market is or will be a thing of the past.

In the UK there are several battery suppliers with eshops, which look to sell genuine 18650s and other Li-ion cells by major makers. Prices range from £4 to £8 depending on what you want. They seem to be long term businesses, not fly-by-nights selling a load of rubbish and legging it. There must be similar on-line stores in the USA.

There's a huge market for 18650s for vaping, which doesn't look like disappearing any time soon. Another source of good 18650 cells is your local vape shop, although they'll tend to be a particular type.

I bought 48 pcs of HG2 18650 from an AliExpress seller that were specified for 3000mAh down to 2.5V.
I've only been test discharging them so far at 1A to 3.0V, and have been getting pretty consistent readings of 1800mAh.

So not great, but certainly not as bad as some reports I've seen - and for the price I paid compared to local trustworthy suppliers I am happy.
I will be assembling these into packs that go inside some 12V SLA shells for backup power application.

Some of my other purchases of 18650 cells and packs in December/January never arrived, but AE did process refunds on those.
