The battery in my Mabis BBT died (after 2 months). It would come on this morning but would not stay on long enough to give a read out. So I used my old therm.
Will that make a big difference in my chart? Should I skip todays temp because of the change?

Hmm, that's a rough spot in your chart to have your therm crap out on ya!
I would use the temp, but make a note that you switched therms and hope for the best. Keeping in mind that your chart won't be very accurate from here on out.
The same thing happened to me this morning and I used a back up thermometer I had also. I logged it in and it seems to fit in with my usual temps. If you do not want to log it, just write your temp in your notes until you can get a new battery.
My thoughts exactly. I will be buying a new battery today.
