The shutter is open and the battery dies (which would only happen with long exposures, of course).
It makes no difference to the camera if T or B is being used -- the shutter is open and the battery dies. Releasing your finger in B mode makes no difference.
Yes, however the chance of that happening is smaller then with the B setting then with the T setting. Like I said. And B already was the standard. Like I said. Like Johan Cruijf said: if you see it, you see it


I don't see how it is any less likely with B - I use a locking remote for >30s exposures - camera set to B, operating just like it was a T.

However, would there really be a problem? Surely the start up once a charged battery is inserted would reset the shutter to a default state.

I've never had a battery die during a long exposure, but it's possible. I assume the only problem is to the exposure. I assume that a new battery solves the problem, but that the exposure is simply not recorded/saved. Perhaps a corrupt file on the card -- big deal.
I see no reason why this would be any different if a B setting was used vs a T setting.
