 +===== charging batteries =====
  
 +Generators are not particularly well-suited to [[electrical:12v:charging|charging lead-acid batteries]] (flooded, sealed, AGM, etc) on their own.  They work best in [[electrical:12v:alt_and_solar|combination with solar]]; the generator handles Bulk charging and solar handles the long-duration, low-current Absorption and Float stages.

 +[Alternator charging + solar can do the same thing for about $950 less -- Secessus]
 +
 +If the generator is being used for some other purpose then by all means add on battery charging.  But running a generator for hours at 5% capacity only for charging is not optimal.

 +Generators //are// well suited to charging [[electrical:12v:deep_cycle_battery#lithium_chemistries|lithium-chemistry batteries]] as that type can take current at all points of charging.
