Interesting, but unfortunately a very different discharging scenario from the one that interests us the most (much slower; order of 12 months or so).
UPS that is UN-interrupt-able;!..

very best self discharge is lithium polymer..but even so I am not sure the life goes much beyond 3 years typically.
Charge is also pretty easy. Just limit voltage to 4.2 v per cell and current to about the same as the hourly capacity, and they are happy.
