Solid Sanyo Quality through and through
I've been using these for four months now, and they are better than NCR18650B
The raised large button top contacts inside more devices than the NCR B did, and on my Soshine H2 charger, I sometimes get 100mAh more usable capacity / sometimes I get 200mAh usable capacity. { It all depends on what state they are when I put `em back on charge. } ( ie. a dead flat charge gives the fuller charge / the hardly off full, top up charge gives the lesser charge )
These things are substatially heavy in the hand; which indicates lotsa juicy raw materials packed inside.
They are quality -- they are NOT copy-cat imposters.
Arrived half-charged only.
4 months ago, they each showed 3.500Volts. I saved one only to continue evaluating its state.
After never having been in a device, nor a charger, etc., 4 months later I still read 3.499Volts, and that has been in house where temp has varied from 9 degrees C to 29 degrees C.
I don't casually notice difference in runtimes verses the previous Generation NCR18650B, but these GA generation
are good.
