Pamela quoted:

a Li-ion battery cycled within 75%-25% SoC (blue) would fade to 74%
capacity after 14,000 cycles.

If this battery were charged to 85% with same depth-of-discharge
(green), the capacity would drop to 64% at 14,000 cycles,

and with a 100% charge with same DoD [depth of discharge] (black), the
capacity would drop to 48%.

Assuming a charge cycle per day, I probably wouldn't care whether a
battery had 74%, 64% or 48% capacity left after 14 years ...
