Ah... true, but the whole point of the adjustablity is to be able to set it where you want for what works best in that application.
There is theoreticaly perfect charging conditions and then there are real life applications.
Also the first sentence was would this possibly work, not this will theoreticaly be perfect.
I dont use theoretical consepts very much, I prefer real life application.
Theoretical says too many things wont work, real life says they work just fine.
In normal daily life usage most batteries are charged up to the maximum voltage and then put into use. Hmm.. isnt using a battery going to drain it down way below its float voltage too? But then when you recharge it are you not bringing it back up to the maximum voltage again?
I could be wrong but what I put in the first post sounds just like a real life charge discharge cycle to me! But under actual controled voltage limit conditions.
Using standard automotive starting type batteries for back up power tends to kill them before they ever dry out anyway. Plus that is why many good ones still have filler caps on them. SO a person can top them off as needed.
I personaly never buy batteries that I cant top off.
The perfect charging circuit is great but for what it cost I can put a lot of water in a battery too!
I just gave out one possible way of doing things instead of peeing all over him for not asking directly for a "super ultra multistage microprocessor monitored battery charger" system.
What the end user desides is utimately up to him.
