Or more seriously, if the battery's not charging, the alternator will just supply less current, and will put less of a load on the engine, so you get fractionally better mpg.

That set up is often used so high-draw auxilliary items (eg. ICE, hefty driving lights, caravan, etc) won't flatten the main battery that's used for starting the car.

I have two batteries connected in parallel in my boat and they charge perfectly well at the same time and have given no trouble for 5 years now.
Once the battery is fully charged Paul, the feedback from the battery voltage shuts the charging rate from the charger down, that is for a regulated charger which is normal. Unregulated overcharging could cause the battery to overheat if the charge was high enough.
