Got it and thanks, boy that wiki takes some digging through.

Looks like I need to get one on order, maybe the 120mAh. The one fitted is
48mAh.

As a quick fix I think I can fit a coin cell holder with a regular CR2038 3v
cell into the battery holes . Don't have anything with a 32.768kHz crystal
fitted in the junk box but could reverse the original, doesn't look polarity
sensitive, and snip the tabs off. A dab of hot melt to keep it in place.
Perhaps good enough until a replacement can be got.

Martin, HS0ZED

An email or phone call to Tentec could save a lot of investigation.
