Silver lining: at least this time around Nissan is being honest that the battery willl have poor longevity.
To put the cycles number in some different perspectives. Some Tesla-like battery numbers:
From the following article on batteries "similar" to what Tesla is using.
Divide those number of cycles by 365 or 300 or whatever number of days per year you want. Pretty long.
"500 cycles? But that’s (relatively) low! Yes. But what is not shown on the spec sheet is that when you partially charge and discharge, degradation of the battery capacity is reduced. Thus, you can do over
40 000 charge/discharge cycles when going from 30% to 70% only. Or over
35 000 charge/discharge cycles from 20% to 80%;
28 000 cycles from 10% to 90%;
15 000 cycles from 8% to 92%,
07 500 cylces from 6% to 94%, and the capacity reduction goes faster and faster, finally reaching
00 500 cycles when recharging from 0% to 100%."http://blog.evandmore.com/lets-talk-abo ... ncr18650b/
