Battery Equalization

[1L243]

Who does it?

What is your method?

[jrnymn7]

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.

I use my inverter / charger and follow the directions to enter into a 15.5 volt charge for 8 hours. it will shut off automatically and enter in to a float charge of 14.2. after that.

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!

I do it. I have upgraded my converter to a progressive Dynamics (14.6) but I have a actual battery charger that will equalize at 15.3

Recently was dry camping for a couple weeks would usually run the gen an hour or so and charge and run her hair dryer etc. After 2 weeks I ran the Quick Charge brand battery charger for 2 back to back cycles for eq. SG came right up.

I also have a Mega Watt 30 power supply that I play with and will sometimes hit batteries with it. 15.4 ish volts

It has now sat a few weeks with very little use when I go check it in storage and battery main switches off and sg is still up.

Hi,

I allow the Blue Sky controller from my solar system equalize the bank every 30 days.

Not if you spell equalization "eqaulization" Well I think after reading some of the past comments, I will just let my batteries sulfate!
