I've posted on this before and want share my findings with anyone who is interested. We went bush last night and ran the fridge for 30 hours (older Engel 39L, draws 3.7 amps running) and lights. Before we left I checked the voltage and it was 12.33, 70% charged according to the chart I use. The batt is a 100 amp job so we had used around 30 amps. Sounds about right.
After getting home (1.5 hour trip) and letting the batt settle I checked the voltage and it was 12.79, fully charged.
AGM's are supposed to accept a quick charge from the alternator, and every time I check it, this has been confirmed. They're expensive, but do the job
well. Just hope it lasts
well, I try not to let it get down too far to help its life. If I'm going to be away for a few days I'll run the car for a while each day to keep it topped up and see how it goes.

Mike,
I bought the "Lifeline" (USA made) AGM, 100 amp for $350. Also available are the "Fullriver" and "Remco" (both Chinese made under USA ownership) for about $250. I only went Lifeline because I was having it fitted to new car and included it in the lease deal.
The bloke from Federal batteries told me that the performance of all was similar and the Lifeline was only better for a lot of heavy usage. For normal usage don't waste the extra $100. I only went with the Lifeline because of the lease arrangement. Otherwise I would have gone for one of the Chinese jobs.
Any queries, talk to the bloke at Federal Batteries,
Sydney (toll free number in the yellow pages), he knows his stuff.
Good Luck
