Thanks for the info Geoff, there are so many takes on this.
I have also done a lot of research on this, you have to be careful to amalgamate facts rather than opinions!
There are a lot of opinions on the net on this subject. Not as many reliable facts.
Once a battery has gone below a predetermined, critical voltage, NOT to zero, then it can become unstable and dangerous to attempt to re-charge it, that's why if a battery has gone below the critical voltage, the correct charger should refuse to charge it.
My understanding of the gradual improvements to Li-Ion batteries is the membrane used to package the 'jam rolley-poly' of chemicals is thinner and more resistant to leakage, hence slight increase in capacity for a given cell and slower self discharge rate.
