 > A [ [[electrical:shore_power|shore power]] ] charger is a stiff source with unlimited energy and time. Your solar is a very soft source of unknown power and only a few hours to get the job done.  - sunking((https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/299490-bulk-absorb-float-equalize-what-does-it-mean#post299490))
+> Charging lead acid batteries is not something that you decide to do, or start or stop. The old statement, "I need to idle the engine for a few minutes to "top off" the batteries." is a prescription for turning expensive batteries into paper weights. You want a system that puts the batteries on charge automatically, every time there is even a single ray of sun or that your engine is running -- DiploStrat((https://expeditionportal.com/forum/threads/dual-battery-system-with-ctek-d250-not-charging-battery-over-12-volts.174927/post-2342346))

 ===== three stage charging =====
-Three stage or "smart" chargers (whether [[electrical:solar:charge_controller|solar charge controllers]] or [[electrical:converter|converters]]) will follow a common pattern.  Battery manufacturers publish different specs for charging and a good charger will let the user configure the charging stages in accordance with that information.

 Common Vfloat values range between 13.2v for stored batteries to 13.8v for banks that are deep cycled each day.
