My anecdotal evidence with Eee netbooks supports it.

https://en.wikipedia.org/wiki/Lithium_ion doesn't say exactly, but the
breakout bar at the top says "400-1200 cycles".  BOTE for 1 full
discharge per day turns that into one to three-and-a-bit years.

Contrariwise, if you had a more moderate use case -- say, using a 12h
battery for four hours, once a week, in an continuously air-conditioned
environment, you would expect it to last a lot longer... BOTE says more
like 16 to 48 years.  (By then probably something else, like the
bakelite-style cracking of the housing, would destroy it.  Or it'd be
useless for the same reason as your BNC network card is.)
