[time-nuts] Oncore UT+ Battery Backup

[Robert Atkinson]

As a side note, I'd use lithiums rather than AA's 

(alkaline) purely because they don't tend to leak corrosive electrolyte all over your expensive electronics if (when) you forget to change them. Lithiums have a longer shelf life too.

Yes, you need to connect our battery via Pin1if not using a rechargeable on board.

So, should I grab a 3V lithium cell and mount off an old motherboard, or should I use a pair of AA batteries in a holder I think I have around here "somewhere"?  Or is it just whatever comes to hand is fine?  I think the drain is only micro-amps.
