Battery Equalization

Gophert 1620, set to 8v and 5% of C, on well ventilated individual 6's.

Who does it:Some of us, not all, but many

What is it: It is a controlled overcharge of the battery

What is your method: RV came with a Progressive Dynamics 9180 with charge Wizard, after 20 hours of FLOAT the Wiz, kicks into a short (15 minutes) Overcharge cycle, that is how I normally do it.

If the batteries are in SERIOUS need of it (Very very very rare) I have a Prosine 2.0, I can command it to do the job as well. This is a much longer and slightly higher voltage over charge.

Bypass my solar controller on a nice sunny day.

My mega watt will do 15.5V, but I set it for 15.0V, for a top charge. The old 6 amp Sears Roebuck manual charger, circa 1979, will provide 16.0V at the battery, if left on long enough, for a true equalization charge. Neither provide Pulse Charging gimmickery.

Wow, 14.2 float, first time I've seen that.

My powermax boondocker will do 14.8. But my charger in the garage will hit 15.7 with the disconnect off & cook them good.

My solar does a higher than normal voltage an hour every 120 days but not really high enough to call equalizing. Voltage max is 15.0

What PD converter does 14.6? Perhaps the above is a typo for 14.4?

Yes, I run Equalization size voltages on mine to get the SG up to true full SOC. That is a different purpose from getting all cells equal in SG, but uses the same method.

:) Hi BFL. Yeah probably 14.4? I cant remember it all exactly from last summer. I usually dont use the PD either. And thanks for all your good comments back then.

Gottahelp our Southern Brethren in need!
