I guess they can be pretty safe from radio interference there, at least :).
I doubt the connectivity issues need to exist, though, probably works just fine in some configurations. What I'm wondering though if they had a spare, and maybe a second spare, and space batteries, on the boat. Or possibly manual override (doesn't sound like it).
I think the device itself is fine, though it might be indicative of too aggressive cost cutting measures.
An article on APNews said there were multiple backups onboard... Which sort of engenders the thought of why they needed multiple backups. I'd be sure to have A backup, sure, but multiple?
My thought is are they from different lots and are the batteries from different manufacturers and different lots? You don't want to have 5 devices and them all from the same batch and all fail in the same way. A company not concerned by safety probably wouldn't consider any of this. I also bet their SOP didn't include changing batteries every time, so you have to rule out that these spares probably weren't getting charged up or have their batteries replaced either.
