If you are just floating the Batteries across a Regulated Powers Supply,

The 1% of the time, where you have actually USED some of the Battery

Capacity, and are in Recharge Mode, the amount of current supplied to

the Battery, as opposed to the attached Load, only depends on the

battery Voltage, to Regulated Voltage Ratio, and that will just slow

charge the battery back to 100% Charge, and the Set Float Voltage.

What does a Three State Charger, give you, that isn't inherent in the

Regulated Power Supply Setup? Just wondering?




Two things. First if you set your single voltage power supply to the
battery FLOAT voltage, it will never fully charge the battery. It can
not possibly bring it back up to full.

Second.. If, by chance, the power company fails to deliver (Which where
I'm from is all too common in these days of layed off tree trimmers) the
3-stage will not only re-fill it but will re-fill it faster.

Plus, depending on the converter... It may have additional filters..
Such as a battery just sitting there can become stratified, When this
happens the liquid near the top of the battery is mostly water, and the
acid is near the bottom... You have now lost a major portion of y our
battery.

The Progressive Dynamics converter I have has specific programming to
prevent this... The same programming also cuts down on sulfation which
is another thing that shortens the battery life.
