I went down their rabbit hole, and a conventional tech CT is 10 hours??

My understanding is that material composition can make a CT scan take a really long time. It makes sense to me that scanning a battery would be pretty slow, given what they're made out of.

I just assumed it would be impractical due to physical changes of the object from multi-hour exposure to X-ray energy.

I don't think ionizing atoms inside a battery will harm it. They don't have DNA.

I don't know about batteries, but ionizing radiation can definitely permanently damage microelectronics, and those don't have DNA either.

Thankfully functionality isn't usually necessary to get a successful scan, unlike living targets.

It can, yes, but batteries also don't have microelectronics.
