Fascinating...

Nice,
facinating,
I just measured the weight of 3 eneloop AAA cells.
2 good ones measure 11.77 and 11.72 gram, fully charged
and one that is bad (high Ri) also charged, measured 12.28 gram
?????
Later I will measure one of these good ones when it is empty.
The bad one (that is heavier!) bounces more...

????

OK, follow up.
Eneloop (those are rechargeable NiMH BTW) do no show a weight difference between full and empty.
A defective one is heavier (this was overcharged in a ^!@%&^!@%duracell charger, it killed several eneloops,
using a different charger now).
The extra weight is probably caused by some chemical reaction grabbing something from the air,
water? CO2? Now that would trigger all them climate idiots,
store CO2 in batteries LOL.
Really do not know, but it is heavier...

Forgot to do the bounce test on the empty one...
