Simply remove any incriminating labels regarding lithium and you should be good to go. This is especially true for a carried-on battery that exceeds 2g Li+. However, you'd probably have to look pretty hard to find such a battery.
Thanks. Per Gardener's comment and yours, I think we're logically safe on the battery used for the CPAP--it is rechargeable and therefore not a lithium-
metal battery.
That said, because it is
1. not part of the CPAP machine per se (it plugs in but can run on 12v), and
2. a generic non-laptop battery, I still wonder if we're actually safe on it. We know it's rechargeable. Will they know that?
It is our critical li-ion battery: he can't sleep without the CPAP, and neither could anyone nearby. We're in United Eplus for most flights, so no plugs. Guess we'll also bring the D-cell holder, even though it looks odd--like parts from Radio Shack, which it is.
I'll have to do the math later: it will run Mr. FA's CPAP machine (and/or laptop if we're not sleeping) for about 10 hours per charge iirc.
I'm increasingly glad we avoided any UK airports for our next trip to Europe: I cannot imagine us getting just our cameras, electronics and supporting equipment into UK-restricted carry-ons. We'd have to be wearing, not carrying, our 1st-day change of clothes.
