Known issues:

  • Leaky Ni-Cd clock battery

The Ni-Cd battery may be leaking, risking damage to PCB layers & nearby components. Promptly remove the battery & clean corrosion/alkaline salts from the board. Use white vinegar to dissolve salts, but exercise caution as vinegar can corrode exposed metals. A thorough examination & repair may be needed.

Notes:

The board pictured has been reworked to accept a CR2032 coin cell. The diode under the RTC chip must be disconnected to prevent charging current being applied.
