The No-Slot Clock uses a lithium “coin” battery—a type that is widely used
in car key fobs and many “keychain” LED lights. I have never known the seal
on this type of battery to fail, causing a damaging leak. It’s certainly
not impossible, but I wouldn’t consider it a significant risk. 

FWIW, I’ve also seen methods of replacing the battery in the NSC.

The last time I checked, the module sold as the NSC was still available
from Maxim (or its successor company). The real time clock module was
widely used “under” both ROMs and SRAMs in lots of embedded gear. 

Also, there is an Applesoft program that was distributed by Apple to patch
the year table in ProDOS for any year range up to 2040 or thereabouts.
