I'm wondering...
How often do you need clean your chain VS how often you need to charge the battery.
Shouldn't be hard thing to keep on top of.

I don't think the ball should have electronics for flight stabilization, but I think you'd find a lot of people (of which I am one) who wouldn't mind a sensor of some sort on each end of the ball for more accurate spots and determinations of whether it broke the plane in bounds.

Things most everyone does more often than they need to charge their DI2 battery:
It's just not that hard to remember, and if it is then there are other issues you may need to address.
Now, if I could only hold off on spending the double secret hidden reserve bike fund until I had enough for UI2
- check/top up tire pressure
- wash bike
- clean/oil chain
- replace chain
- charge headlight
- replace batteries in tail light
- charge cell phone
- wash kit
- buy schwag
- pay mortgage
- call your mother

Someone just needs to come up with a way of impregnating a cf frame with solar panels to trickle charge the battery and you'll no longer have that problem. Hey, I should put that in the next big thing in cycling thread, or just see if I can get a patent. Pcad, you draw me up some good pictures, and I'll cut you in.

FYI, I just passed mile 1,200 on the new charge and it's still going strong.
And after almost 3,000 miles, perfect shifts. Every time.

I'm sure few of you have captained a tandem. In some ways, it's like driving a charter bus: the transmission is 7' behind you, and you probably can't see it if you look. When stoker-wife nags that I need to trim (because I only hear it buzzing half the time), I guess which way to go and hope I don't land in the next ring (we have four to pick from, at this point). I want Di3 when it comes out, because I have no doubt it'll be better than the mid-grade components on our otherwise-amazing ride (top-end components aren't available for the gear combos daVinci sells).
I have a plastic bin with the five chargers relevant to our bike (two Garmin, one Niterider, one Canon point/shoot camera, one iPod). I figure I'll either charge the DiX when I charge everything else, or charge it when I charge the AAAs in our headset intercom or taillight, or charge it when I clean the chain (monthly). Can't be too hard.

Interesting, this time my Di2 battery only lasted 893 miles, before the low battery warning indicator started flashing. I wonder if I'll start getting less and less miles per charge.

It makes them have a longer life.
Draining them almost completely, like the OP did ... is a no-no with Li-ion.

Good to know. And that's a good design.

I think I'll just charge the one on my wife's bike on the 1st of every month, whether it needs it or not.

Ya know, all it'd take to make this whole discussion moot would be one good EMP.... But then there'd be no way to discuss how moot it'd be, now would there?

But until I get that money tree in the back yard ready for harvest, I'll be sticking to My RSX group that works pretty good almost all the time.
On the battery issue, how many people carry an extra cable on regular rides. Seems like if the issue is battery vs. cable, either one not working the way it's supposed to without a backup is going to have the same result.

In contrast, the batteries depreciate with constant charging because they form electrolyte deposits in the cell, which are accelerated at full to high charge levels and at warm to hot temperatures... so storing them in the fridge (NOT freezer) is a good way to extend the life of the battery... and of course letting the battery get low before charging is also good at extending the battery life.
The attributes you described are true of Lead Acid batteries.

There just seems to be something to me that feels fundamentally odd when I think about using a battery and a micro-processor to shift my bicycle . . . . my bike! . . . I don't know why I feel that way, I can appreciate the technology, but it just feels odd inside for some reason.

How about that support for di2?
I have seen quite a few threads come and go about how someone just spent their life savings on a dream bike with di2 and Ut-oh! something isn't working.
So say you just got your bike with di2 and you are out on your second ride and you suddenly can't shift. What do you do? Take it to your lbs. But wait! Your mechanic isn't an it guy! You will have to send that part to Shimano, a company that makes MECHANICAL fishing reels, MECHANICAL rowing parts, and up until now MECHANICAL bike parts. So let's face it, Shimano isn't technologically inclined, and all they want is your money, so no they won't be spending the $1000 it costs them to replace your $3000 groupset. They will have some guy, that specializes in mechanical groupsets and took a one week training seminar on electric groupsets take a look at your broken part. He will replace many pieces until he can say "good enough" after seeing that it works sorta good.
So now you are super excited that you have finally gotten your dream bike all together when, oh no, your part still does not work! You take it back to your shop and the cycle begins again.
Seen it too many times around here.
Then there's the cost.
