Well, I've also had a battery by Panasonic, I think it was rated
at 3400. I had initially bought it for the Tecsun PL-880, but I
have also used it in the XHDATA.
It would last about 4 hours. The original battery being a 2000 mAh
type and lasting 2½ hours, this is coherent.
The 9900 mAh battery I have has now been used in the XHDATA for a
little less than 11 hours and is still going strong.
So either the orignal battery and the one from Panasonic were
junk, or the tests that you refer to are not accurate. I don't

Hello Rémy Friess,
I became curious whne I saw this 9900 mAh battery so I found some
tests by several people. I was curious because I use many 18650
batteries and am always looking for something with higher
capacity. In short the batteries like the ones you mention tested
at only a fraction of the listed capacity. In all cases they were
under 1000 mAh.
I can only guess that if the 9900 battery is giving you more run
time, the original had to be a very bad cell. I think that if you
got a genuine cell from LG, Samsung, Sony
or Panasonic/Sanyo rated at 3400 to 3600 mAh you would get
better run times than with the 9900 mAh rated cell.
A good one would be the NCR18650G
by Panasonic. But there are others depending on if you need a
button top or flat top and with or without a protection PCB. If
you stick with one of the big 4 and buy from a reputable
dealer (does not sell Chinese knockoffs) you will be much
better of than buying no-name batteries with ridiculous ratings
from some place like Ebay.
BTW, In this context "genuine" means that
actual capacity in real use and/or testing matches what is
advertised for the cell in question. for the 9900 mAh battery
this is not true, therefor it is not considered genuine.
