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.

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.
