I would vote for a lithium AA. Something like a Tadiran TL5104 3V6 @ 2A10 hrs

I remember reading in one of the docs I have for the Oncore that Motorolla recommended a battery over a cap mainly for practical reasons.

It was an expedient until the day I run it on batteries. As for backing up the Oncore, power outages are not the only reason. I may need to power down the GPSDO to add mods or other reasons may arise. Having the almanac stored will help. I would still like to know if using a supercap is ok. They are made for memory backup, so why couldn't I use one for the Oncore? I have a few different values on hand.
