 **[[http://rvwiki.mousetrap.net/doku.php?id=electrical:12v:deep_cycle_battery#agm|AGM]] lead-acid batteries are not well suited to solar-only charging**.  They cost about 2x that of FLA, have less capacity, require vigourous charging and cannot be charged as high in voltage.  They remain popular because people think "$$$ is better" and are loathe to vent their banks.
-It is possible to have one all-purpose battery for both house and starting.  This only works when [[electrical:solar:sizing#your_daily_power_needs|daily power requirements]] are quite low((40-50Ah/day)) or when [[electrical:solar:nonessential|opportunity loads]] are agressively utilized.
+It is possible (though uncommon) to have **one all-purpose battery for both house and starting**.  This only works when [[electrical:solar:sizing#your_daily_power_needs|daily power requirements]] are quite low((40-50Ah/day)) or when [[electrical:solar:nonessential|opportunity loads]] are agressively utilized.  There are two approaches to such a setup:
+  - the premium battery deep-cycling approach as used by Sternwake((http://www.cheaprvliving.com/forums/Thread-Has-anyone-heard-of-Northstar-AGM-batteries?pid=135811#pid135811)) This requires attention and knowledge.
+  - the "make do" [[electrical:solar:shallow_cycling|shallow-cycling]] approach.  This is more suitable for car dwellers and folks on limited resources.
