I've only read about them.... But I would like to know more... Don't they
just continue to degrade after instalment??? So use it all soon as
opened???... I would like to build a R/C "parkflier" and 40% lighter sounds
better... 40% lighter than what??? From what I've seen the guys are using
lithium cells and getting 20-25 minuets flight time...

equivilent 9V battery. I don't think they degrade quite like that though.
I'm going off of marketing material here, but they are used in telemetry
application where a circuit needs to be energized continuously. They're
especially used in medical applications: hearing aids, health monitors, etc.
And everything says they are the longest lasting telemety battery.
