and do need to be fully discharged to allow them to be fully recharged again.

LiIon batteries will never charge if they go below about 2.3 Volts. These batteries have a safety circuit that will make them appear dead once they go below 2.5 volts.

The characteristics of a LiIon battery will not improve its life expectancy by having two batteries (2x 6-Cell packs). You are better off getting one high-capacity (1x 12-Cell pack). It will be cheaper and provide the same life. Unless, of course, you keep the spare in the refrigerator at a 70% charge.
