Portable battery charger
Looking for a good portable charger for deep cycle 12 volt batteries, something that will desulfate as well as equalize. Having a hard time finding a smart charger. From old posts I see a lot of reco...

Equalization for eighty years remains THE approved way to correctly "de-sulfate" a flooded lead acid battery. So-called "pulse charging" is a gimmick. For hundreds of batteries, I compared the energy (kWh) of pulsing a battery versus straight DC current charging kWh are there is not one whit of difference in the amount of hardened sulfation removed from positive plates.
The output of a transformer based charger is half wave 60Hz, from a solid state charger the pulses are according to the frequency of the PWM signal. How did I PROVE THIS? By dis assembly - and using a 20X loupe and actually examining cell by cell, plate by plate the results of the tests. Had pulse charging been authentic I would have patented it, and made millions. NO ONE and I mean ZERO firms had the high frequency or high current adjustable power that I was using. I had to admit defeat. One manufacturer offered me more than seven hundred thousand dollars to put my credentials on the line behind their product. I refused. Call me stupid. This is the age of cheaters and liars. Charger manufacturers who CLAIM their product is "Patented" either hold no patent at all or the patent is for some other feature on their charger. Please read up on the difference between PATENT PENDING and a genuine patent.
Lots of "smart portable battery charger" companies are in hot water financially because of warranty returns. If you can tolerate a little do-it-yourself work an adjustable power supply is my choice for a solid-state charger. As far as gizmo chargers are concerned I can offer no advice except I have several that stopped charging and are now designated as a waste of natural resources.
