[RE-wrenches] Desulfators

[The Office of Tom Duffy]

Chris
 
Over the years I have looked at the various incarnations of these devices. I
have two thoughts on this subject the first is a cheap constant current
battery charger (2Amp) left on for two weeks or more will slowly melt hard
sulfation. if that is the problem, the time it takes might not be worth it. 
 
My second thought is if the battery system is designed right in the first
place there will be no sulfation issues (unless the bank is pulled down and
left that way) I never parallel battery strings I just use a single series
string, if done this way there will be no sulfation at all and battery life
nearly doubles.
 
Contact me off list 575-539-2111 and we can discuss this

I have a picture of one that burned up pretty spectacularly. (definitely a
fire starter) I wouldn't hook them up without fusing..... 
I think modern charge controllers with PWM and temp comp do the job of
desulfation adequately and safely.

We sell them, but don't push them much. while they will do some good for a
battery that has a sulfation problem, quite often the battery that won't
hold a charge has multiple problems, which desulfation will not fix.

Dear folks:

What is y'all's opinions on desulfators? I have a customer who is having to
do a battery upgrade, and someone's stuck a bug in her ear about them. I
figure proper battery care is most essential, but I am interested in hearing
about your experiences.

Thanks so much for your information!
