HP 15C CE ships with mediocre batteries

FYI I just changed the 2x cells in my HP-15C CE and HP-12C+. "Pr Error" both times even though I swapped one cell at a time (they're in parallel). The original cells are gone and Energizer ECR2032 (240mAh) ones are ordered.

The stuff in the HP-12C+ has been re-entered (no VoyagerSave functionality--you listening Moravia?) and my HP-15C CE is currently in 16C mode with programs being entered/saved.

All a PITA but do once.
