 **[[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 "$$$ is better"​ and are loathe to vent their banks. **[[http://​rvwiki.mousetrap.net/​doku.php?​id=electrical:​12v:​deep_cycle_battery#​agm|AGM]] lead-acid batteries are not well suited to solar-only charging**. ​ They cost about 2x that of FLA, have less capacity, require vigourous charging and cannot be charged as high in voltage. ​ They remain popular because people think "$$$ 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.
