Glide fast enough to have windmilling hydraulics on G+Y for flight controls.
Forced landing/ditching before the batts fail.

Abnormals/emergency drills assume everything else is working.. you will have to figure it out yourself from the available references...
QRH 1.01 ELEC EMER CONFIG SYS REMAINING has a column for BAT ONLY in flight... big picture stuff:
FLY .. PFD 1, IR 1, ADR 1, ISIS
NAV .. VOR 1, ILS 1
COM .. VHF 1
I'll leave you to figure out stuff like Landing Gear...
Yeah, you still have green and yellow hydraulics but presumably once your 22 mins of battery power is up you're on mechanical backup.
True - but here's something to investigate.. can you control the engine thrust with dead batteries?
