“The vessel surfaced and it reported a breakdown,” naval commander Gabriel Galeazzi said. Capt Galeazzi spoke of a “short circuit” in the sub’s batteries.

On the surface and they couldn't just run on diesels? Further, no communications? They would to have suffered a total electrical failure wouldn't they, disabling all comms. It just doesn't make sense.

Are the men alive ?

Can they survive much longer ?

How long before rescue attempt(s) ?
