I have discovered a great spreadsheet on the electric vehicle wiki website

http://electricvehiclewiki.com/Battery_Capacity_Loss

On there is a spreadsheet with a model for the Nissan LEAF battery degredation.

I have put in my details and found the results quite reassuring.
Whilst the LEAF suffers a rapid loss of capacity in the first few years, it levels off over time.

I've added a couple of columns at the end of the spreadsheet to give range at 100% and 80 % charge over its lifetime (assuming 75 miles range when new).
Reassuringly after 15 years the model still predicts a 50 mile range.

(I tried to paste the columns but the formatting went wrong so I have removed them)

yeah I wouldn't buy a LEAF in a hot country, although apparently a new battery chemistry will help fix this problem.

Years in Service 2.69
Total Mileage 31910
Predicted Total Loss 13.72%
Actual Loss 5.00% (3.368Ah)
That doesn't sound correct. Are you sure your location is UK? as it uses this for average temperature.
My prediction is 83% capacity which is spot on.

When I click on your link all I get is info, I see no spreadsheet.
The spreadsheet is halfway down the page: look for "The Battery Aging Model (version 1.00)"
Although some of the links are broken the google one works.
