"Equalizing" Deep Cycle Batteries ??

12 posts in this topic

Howdy,

I have a Minn-kota on board charger with 2 deep cycle batteries for a 24 volt system.

I was paging through the manual and it said to "Equalize" the batteries every 50-60 clcles ot 2 months. It says this will extend the life of the batteries...

It says to hold down a button for 10 seconds, it will flash and send 17 volts. It then says it my take an additional 6 hours of charging time.

Question is, how long do I keep it in that mode ?? confused.gif

Do I just leave it in that mode and it'll end it by itself ?? confused.gif

Has anyone "Equalized" their batteries ??

Thanks...

Never done anything like this and never had a battery related problem. Just charge your batteries regularly and you should be fine.

Go to the Trojan battery site and click on tech support. They have a lot of good info on battery maintenance, including equalizing batteries.

I may have that same charger.

I have done it a few times and it's automatic AFAIK. If you follow the instructions, it will take care of it all on it's own. My batteries are working fine and I believe this will be year 5 or 6 on them.

Basically, "equalizing" the batteries is a technical term for applying a fairly high voltage in an attempt to dislodge or reverse any sulfation of the plates.

I would recommend disconnecting everything else from the batteries except the charger (or ensure power to accessories is completely turned off).

You may also want to check the water level before and after, and also be sure they are well ventilated. They really gas quite a bit during equalization.

I believe this is only relevant to flooded-cell lead acid batteries. I think it would not be a good plan for gel-type batteries or maybe even AGM - but not positive about that last one.

What is "AFAIK"??

Yes, only for flooded, lead-acid batteries.

Mine is going on the 5th year...

The manual said they do out-gas & boil - that is normal.

So, I just initiate the equalization and let 'er go...??

Thanks 99 & anyone else that can chime in on this..... smile.gif

Just found this........

"Flooded battery life can be extended if an equalizing charge is applied every 10 to 40 days. This is a charge that is about 10% higher than normal full charge voltage, and is applied for about 2 to 16 hours. This makes sure that all the cells are equally charged, and the gas bubbles mix the electrolyte. If the liquid in standard wet cells is not mixed, the electrolyte becomes "stratified". You can have very strong solution at the top, and very weak at the bottom of the cell. With stratification, you can test a battery with a hydrometer and get readings that are quite a ways off. If you cannot equalize for some reason, you should let the battery sit for at least 24 hours and then use the hydrometer. AGM and gelled should be equalized 2-4 times a year at most - check the manufacturers recommendations, especially on gelled."

I think it is an insurance company...the one with the duck?

Or...As Far As I Know.

Heheheh.... AFLAC

Yeah, AFAIK - "As Far As I Know" - internet slang stuff, you know.

So, the moral of this thread is: Get out there & Equalize your Batteries !!! wink.gif

How could you equalize your batteries if you don't have a charger that does this. I have a 3 bank dual pro, does anyone know if this one equalizes batteries?

There is a product called Power Pulse that will do the job for you. Manufactured by Pulse Tech. Google “Power Pulse” you will find places that sell them online. The unit connects directly to the battery, is self powered and you leave it connected permanently. I recently purchased a 24 volt model for $60. Companies that run fleets of battery operated equipment like pallet jacks and lift trucks use these as well as golf courses. I have not had them long enough to know if the claims are true but they say you can double the life of your battery. If I can get 6 – 8 years out of a set of Trojans, then the money is well spent.

A good suggestion for all, equalize your Lead/Acid Batteries.

      What a novel concept!  Talking fishing on a fishing forum to increase interest and activity.  You may be right, it could work!  
    • leech~~
      So let me see if I understand this? You guys on the last page or so are going to "Lets Save This Forum" by high jacking the thread and talking fishing now!     Dam that could just work? Carry-on!   Good Luck.

      Thanks guys for the tips looks like 3-4inch stick bright stick baits and bright spoons seem to be the go to.  Anybody ever vertical fish them or live bait? Hope the weather is.good next friday, i have always wanted to get out there and try it.  Bonus is the wife would be happy with some fresh salmon.

      I have been looking at the gages this morning and the L.F. still appears to be either frozen or have an ice jam at the most downstream gage in Little Fork. The discharge is not working but the water level has risen 3' since Sunday. The next upstream gage however is flowing good and has risen from 1,200cfs to 5,000+cfs since Sunday and has risen 8' in the same period. The Big Fork doesn't have cfs data so I am thinking its frozen but the height has risen 2.5' since Sunday. I would think with that flow and the warm weather it's only a matter of days until they both go.   Other trips like the Black River and Rapid River are all on the rise both cfs and height.   Also, I took a look at the Rainy at Manitou Rapids and it has risen about 2' and has gone from 14,000 cfs to 17,500 cfs since Sunday.

       I'm heading up Friday. Going out of spring steele. I have a delivery route that took me up there today.  Took lunch at the warroad access. They got it closed with yellow tape.  If anyone heads up earlier an update would be great.  I'm planning on an atv but will walk if I have to.  Thanks.  Good luck and tight lines!!!
