batt pulsers , any good ?

 i.e. devices for recovering a sulfated batt bank .
thanks sam c .

 

   Those pulsers may (or may not) prevent sulfatation, and they may (or may not)
help a battery that is only slightly damaged, but regardless what the gadget
manufacturer tells you, the only way to save a truly sulfated battery is to
recycle it.  There is no magic out there.

I built one, (one of the schematics on the web) and tried it out on a 50ah
marine battery.
Battery voltage was 11.46 at the start after charging for a day.
After a week the battery voltage did rise.
After 3-4weeks I did manage to get the at rest voltage to 12.65
I would say that they do work.
But becareful that  you dont over do it, it'll break the plates apart.
I did notice, periodic discharge and charging during the process moves things
along.

I have a Black & Decker Smart Charger that has a built-in desulfating cycle.
I've had improvements on wet cell batteries that were not too-far gone.  In
general I've found that when fully charged the batteries will have a higher
specific gravity after they've gone through a couple of desulfate cycles.
On some really bad batteries it seems to finally do them in.

My charger also has an Equalize button.  This helps too on batteries that
are not real bad.  It helps the most if the batteries are equalized
regularly and kept charged.  The best thing is to keep your batteries in
good shape from the start.

thanks every one , I will prob build one from the meny circits on the
net , I have also discovered the source of the low s.o.c problem , un be
known to me the inverter was being left on over night .
thanks sam c.
