How would battery replacement kill a hard drive?

Re:  MBA 11", late 2012 (mid?)

After installing a third party battery, I restarted, only to get "? Folder," indicating

no system found.

I got to Disk Utility through online recovery and found that my former HD is not showing.

After getting the same results when resetting the SMC I put the original battery back in and the same problem immediately repeated - no system, no hard drive.

Is it possible I somehow killed the HD [an upgraded OWC flash disk (and good memory); or is there some way to detect if it's still there?

FWIW, I was about to update aging batteries in 2 other MBA's (13") and an MBP (13" of similar vintage) that the wife and I use. However,  before I have them all under water this Mac old timer (hobbyist+) sure would appreciate some direction. (I'm okay with some technical diy, but not coding.)

Thanks kindly in advance.
