Suspect Eneloop testing:

What they all (or most of them said).

And


(i) Weighing cells often tells you much.

(ii)  Charge N cells to full charge.
Make some of N "ordinary" NimH cells.

Leave stand for as long as convenient.
Probably 1 week enough.
Charge cells again, measuring the mAh needed to regain full charge.

Real and on-trial Eneloops should be low and similar.

Normal NimH should lose more charge when standing.
SOME std NimH do much better than others in my experience.

LSD and non-LSD should be distinguishable.
(LSD is in the sky with diamonds)

(ii)
Discharge tests
Note that this test is NOT about capacity per se but about curve shape-
Eneloops claim to be different. See below.

1 ohm will give close enough to 1A discharge across the range as to be
considered constant for this purpose.
Charge batteries fully.
Measure and record O\C voltages.
Starting simultaneously, apply 1 ohm load (2 Watt rated) and measure batter=
y
voltages immediately and at N minutes breaks.
N is up to you. If I was doing this manually and had up to 8 cells and was
going to sit in for the duration I may make N=3D1. ie 1 minute readings. Th=
is
would tell you interesting things.
BUT 5 minute steps would be good enough until you neared end point.
Set an auto reset timer to 5 or whatever minutes and read when summoned.
If you haven't got an auto reset roll over timer get or make one. You will
find much use for it over the years.

Take cells off discharge at predetermined endpoint voltage - maybe 1
Volt.Look at spec sheets and decide.

Eneloops re liable to have lower mAh per mass than non Eneloop.

LSDs may be real LSD but clones.

Note that Eneloop claimed voltage per  time discharge curves CLAIM to give
higher voltages than std cells. IF this is true it will stand out for real
eneloops and maybe for proficient clones.

 (iii) The chances of them being genuine are only modest. The chances of
them being proficient clones are fair. The chances of them being bad clones
are fair. The chances of them not being LSD at all are finite.
