I've had my Zero SR since the end of January, and the past few months I've been keeping a daily spreadsheet of the SoC left when I get home from my commute in the evening. There are, of course, day-to-day variations, but the trend has actually been UPWARDS since the beginning of my data set. That may be just an anomaly in the (still rather small) dataset, but it's actually somewhat pronounced. There are possible explanations: variations in traffic level may be the culprit (since going slower increases range, and the unemployment rate in CA is going down fairly fast, increasing commuter traffic), my riding style may have changed (though if anything I think I probably ride faster now than I did earlier on), there may be some break-in phenomenon where the battery capacity increases slightly for the first several dozen uses (I'm skeptical of that).
I'm thinking, though, that what I'm seeing might be just due to the weather. It's a lot warmer now than when I started my spreadsheet, and I'd guess the sweet spot for battery capacity is not far below where they start having problems from being too hot (i.e. if the maximum temperature you want them to experience is 160 F, the maximum capacity temp may be somewhere around 140 F, or even 150 F).
So I thought I'd ask if anybody else, like me, has an often repeated ride, and has been keeping track for longer than I have. Can you see seasonal fluctuations? Is it pretty pronounced or just barely visible? Does anybody else have data to back up the contention that higher battery temps are good, up to a point?
