Does a smart charger for flooded batteries have a time setting that automatically switches to a finish current? I would like like to use my charger to mimic what the smart chargers do. I dont have to wait for the 4 hour maximum absorption time to drop the voltage
First did you mean to type 8V or did you mean 6V?
Due to the way you worded the rest of your post.. the answers are the same no matter which you meant.. But I've not seen an 8/16 volt RV. only 12 volt (Two six in series make one 12). I also make many typos.
Now.. to answer the question above yes and no depending on the charger.
Some (IE Parallex 7300T switch modes based on an internal clock
Some (most smart chargers I suspect) Measure current and voltage.
Some.. are not as complex as their instructions.
For example my Progressive Dynamics wizard Controlled speaks of 3-stage charging but as I recall the output voltage in "Bulk" mode is the same as in "Absorption" (The current drops is all) And from what I can tell that is the best.. From my voltmeter readings (I have a volt meter on a wall where I frequently look at it.. (Across from what is sometimes called "The Throne" you know the room where you use that roll stock everybody is panic buying now days. I'm a frequent flyer there for ONE reason, occasionally for TWO) anyway I see it dropping to "battery only" voltage from time to time so I think the wizard is basically pausing the converter in order to check battery voltage and changing modes based on that.
But the bottom line is there are many ways to do it and different multi stage converters may use different systems.
Oh the parallex 7300T that' T for Two and Two for Tea (As the old song goes) is a TWO stage.. bulk for a period of time THEN float. no absorption.
