Will Di2 levers/shifters work without being connected to battery?

Building a bike and just wondered if I can use say, Dura Ace Di2 shifters with Ultegra 6700 gears, manually?

I don't see a problem if your rear mech is 10 speed and so is your freewheel and so are the shifters.
They should work as if it was just mechanical and not electronic, or am I missing something?0 -
Eh ? What ? Well no because they don't pull any cable through so your gears won't change.
Brakes yes. Gears no.
Or am I misunderstanding you?
Oh and no battery - no changes. Otherwise why would you need the battery.0 -
Yep, it's electronic. Works with wire and motors, not cables.I don't do smileys.

You're missing a lot of winking smilies, as you must be joking...0 -
Ok so now I know. been looking around at a few video's and none mention that NO cables are involved.
New to this so was under the impression that you changed manually via a cable and the electronics part performed micro adjustments for the perfect change.
Which begs the question what happens if the electric cable gets cut?
Needless to say, so I will, I won't be bothering.0 -

The same thing that would happen if a steel cable got cut...0 -

You can always carry a spare cable though.0 -

Sounds like Di2 is not for you...0 -

Dead right mate. Always found with mechanical things you can almost always find a solution to a problem to get yourself through.
It's a lot more difficult with electronics.0 -
I suggest sticking to a steel single speed.I don't do smileys.

Which kind of begs the question - why were you considering electronic shifting in the first place?0 -

Is it just me or are there lots more of these threads recently?0

Just for information. I saw some cheap Dura Ace Di2 levers on Ebay and wondered why.0 -
Why what, why they were cheap?0

Quite a lot it seems. Knowledge of the subject, experience and manners to name a few from your posts so far.I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.0 -

Not quite. Cut a mechanical gear cable and the mech goes straight to the smallest sprocket / ring.0 -

So what?..you still end up with an inoperable mech, either way.. :roll:
Seriously Nick - you need psychological help. You've been banned four times already and you still have this tragic need to come back with yet another new username and post more stuff which is pointless, irrelevant or just flat out wrong. Take the hint...0 -

You were wrong about what you said though, the Di2 system will leave you in whichever gear you were in when the cable failed, the mechanical one will put you in a different gear, that’s a significant difference, which I thought was well worth pointing out, and certainly isn’t “wrong”.0 -

In the context of this thread it isn't significant in the slightest. The OP is clearly a bit dim, and Imposter's response was obviously intended to highlight that, not get into the technicalities of how Di2 works.
Your pedantry is not helpful in the slightest.0 -

Only in your own clueless imagination was I wrong. A cable break will render both mechs inoperable - if you want to debate that, go and do it elsewhere and stop embarrassing yourself here.0 -

That depends on your point of view I guess. Maybe the OP is still around, maybe he now knows something new.0 -

The OP will certainly have learnt to disregard your fanciful nonsense in future..0
