> my LiIon cells seem to hardly lose any charge when left
unused for 6 months to a year...

Seems like the things I own that use Li-ion (cell phone, Kindle),
need frequent recharging, independent of use, but a sample of
one is hardly a trend line.

I have some Sanyo industrial NiMH 1500 maH AAs I bought in
1998 that still push out 900-1000 maH. That these fellows fed
off my LM317 1A constant-current homebrew charger for many
of those years seems remarkable to me.

I monitored cell voltage & quit at 1.50 volts, with the odd foray
to 1.55 or so due to malfeasance. Hot days I quit sooner.

Seemed to work...  :)
