I believe, not 50 to 100. Probably a typo in the first post?
Actually, Tony claimed:
...Battery temperature segments displayed 6, indicating temperatures between approximately 50F (10C) to 100F (38C)...
But glad to see someone finally asked about the most important data Tony chose to umm, gloss over
Bob, can you estimate what your battery temperature was during the final charge? You didn't happen to park Your LEAF in a garage heated to say ~80 F, for many hours prior to the test, did you?
have had a battery temperature in San Diego in February close to the same as that in Phoenix in September, As Tony implies, but it would certainly have required some sort of "active battery temperature management" to get it there.
Hi: Temperature in my garage while charging the morning of, and day before, was generally low 50's to mid 60's. Thx, Bob
I noticed Tony has now corrected (?) his "article" here:

" onclick="window.open(this.href);return false;
But not his post on this thread, and now states:
Ok, at least one mistake in my data was pointed out; the battery temperature was between 50.5F and 74.3F with 5 temperature bars showing, not 50F – 100F.
If your car began and ended the drive with 5 temperature bars, and the bars express the same temperatures in the 2013 MY as in the 2011-12, your car appears to likely have both charged and the ran test with a battery somewhere between 25 F and 35 F cooler than the 6/7 temperature bar test LEAF which Tony is using as a reference. So, if your 2013 has the same available battery capacity as the earlier LEAF, you probably had about a 3-5% lower battery capacity to begin with.
The unknown but obviously significant lower ambient temperature, the lower altitude, Tony's extra weight in your LEAF, and the likely inability of Tony to match the driving efficiency of the cruise control used in the earlier test, were all additional handicaps your LEAF suffered, in the range comparison to the LEAF driven in Tony's poorly documented Arizona reference test.
So Tony's conclusion that your range test shows:
There is no more nor any less range with a 2013 LEAF under these conditions that a 2011 or 2012
Is in my opinion, clearly erroneous.
This does not mean that the 2013 LEAF necessarily has greater range than a 2011-12 in these, or in any or all other test conditions. It just means that we will have to wait for a competent party to perform a better-designed test, to reach any useful conclusions.
I hope you and other 2013 LEAF drivers will continue to give it a try, and as I suggested earlier, also monitor recharge capacity after any range tests, as I think this is also very useful information to collect from any "100%" to known low-state of charge event.
