About a year or two ago folks were posting how good the Vector Battery
chargers were. Any current comments with model #'s???

I have a few AGM boat batteries that are sulfated up and in need of a
charge. They are off the boat and in the gararge but my current charger
won't charge them.

Does your current charger have a pulse desulate mode?
If not, one that does will likely get it charging again.

I've had Vectors, but the one I use now is made by Schumacher which I like
better. Both Vectors that I had quit working after a few uses. At the
beginning of the 3 stage charge cycle the Schumacher senses the amount of
current flow and if not correct automatically switches to a desulfate mode.

Occasionally in the desulfate mode it will run for a while and then shut
down with an error indication because it was not sensing any (or enough)
current flow. I discovered that if I unplugged the charger and started over
it would eventually get through the desulfate mode, cleaning the plates and
into the bulk charge cycle.

WRONG....You have a few AGM boat batteries that are sulfated up and in need
of REPLACEMENT, not charging. Charging isn't going to fix them....

Do you know if AGM batteries suffer from desulfation?

I've never read anything that says yes and I honestly don't know.




I did a little reading up on them because I didn't know either. It appears
that the answer is .... yes.

According to several sites that I just read .... AGM batteries can indeed be
desulfated if they are not too far gone. Worth a try anyway.

I forget the Vector model number I used to use, but here's the Schumacher I
am currently using and it seems to work well so far.

I have lots of batteries that need to be charged, particularly in the spring
and this one brought them all back to full charge plus desulfated them. I
have never tried it on an AGM battery, however there *is* an AGM setting on
the charger under battery type.

Little more trivial information:

Desulfating batteries is accomplished in a couple of ways. One way is also
called "equalizing" and involves the application of a high charging voltage
(typically 15-15.5v) for a period of time.

The other way is using a high frequency, repetitive pulse to the battery to
blow off the sulfated plates.
AGM batteries require this method ... and not the high charging voltage
method. The charger I have utilizes this type of desulfation for all
battery types.

Follow up to this: AGM batteries require the high freq pulse method of
desulfation.

Further reading suggests a controversial subject. Some say you can, some
say you shouldn't.
If I had AGM's that would not take a charge, I'd try it (the pulse method).
Nothing to lose.

I know it works well on the lead/acid batteries in the cars and tractor.

Oh! Now I remember why I know it works. The Harley has an AGM battery and
although it was fairly new it was completely dead last spring. That's when
I discovered that the Vector had died, so I tried to charge it with a
regular battery charger. It would not charge ... didn't allow any current
flow to speak of at all, even though the charger was putting out 13.8 volts
or more. I went out and purchased the Schumacher and tried it. It tried
to charge, then automatically went into the pulse desulfation mode. (You can
hear it pulse and a light comes on indicating it's in the desulfate mode).
It ran like that for a while, then switched to the bulk charge mode and the
current came right up. I left it overnight and it took a full charge.
