I too have the Link 2000. Yes, Battery #1 is normally the house, and Battery #2 the start.
Here is a link to the manual: http://www.xantrex.com/documents/Discont...endor).pdf

I would also gladly email to you if you get me your address.
The inverter/charger does not directly charge the start batteries. You probably have a device called the echo charger that will in theory send some charging current to the start batteries after the house batteries have been "satisfied".

My house batteries, over a long time ( years ) started taking longer and longer to reach float. Eventually they would not and I went to new batteries which it seemed went to float very quickly.
