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. -- -michael - NadaNet 3.1 and AppleCrate II: http://michaeljmahon.com
