Battery Charger Refresh cycle
My battery charge has a “Refresh Cycle”. Does anyone know what the refresh cycle does? How it works? Is it good for the battery? Harm it?
I can only guess…Maybe the lead in the plates (Pb) mixes with the acid (H2SO4) and forms PbSO4 and the refresh cycle vibrates the plates and knocks it off?.
I was hoping some actually knows the correct answer.

I believe it brings the battery all the way down, removing the memory cycle, also desulfering the plates, then it brings the battery backup to full charge. That is what a refresh does to my old camcorder, anyways.

It does not seem to bring the up or down. My guess is it desulfers the plates. Not sure. Not sure how it does it. Also, does not knocking of the PbSO4 cause the plates to eventually arc and kill the battery?

Most all lead acid batteries have a float and equalize charging rate. Float is 13.5 volts, and is fine for normal use. Lead acid batteries unused for standby purposes are "equalized" at a higher 14.5 volt rate 6 hours per month. This insures all cells are fully charged.

Hi FB007: I have to admit, I am not sure what you meant exactly and how this relates to a refresh cycle. Could you elaborate a bit further?
