Netters,
Ken Burton, or someone, gave some tips on salvaging sulfated
batteries.
I'm working on a Little Rascal mobility thingie for the widow of
a friend.
I installed new batteries in it, but he never got to use it.
Unfortunately,
they didn't do anything to take care of the batteries. It uses
two 6-volt
batteries in series, like the GMC house batteries. Boy, are they
expensive.
Helpful hints are appreciated.

I was at The Rally here in Louisville on Thursday and Friday. At one of the
many booths a guy was selling a chemical that desulfates. In his seminar he
claims a high rate of restoring batteries. He also claims others that
"renew" a batter tend to drop the battery to knock of a bit of sulfate
buildup. Well, that isn't a good idea because the deposits are left in the
battery. The chemical treatment works to "rebalance" the acid. He said, if
you want, you can put in the chemical, wait a few days, suck out the old and
put in new distilled water, charge the battery, and use it with some
extended life. The chemical, if you add to a standard, deep-cycle battery,
will work to resist the sulfur buildup and get extended life.
In talking to another guy that had used the produt he said he got more than
eight year's use out of four batteries; more than he'd normally gotten. He
may have been stretching the truth.
The product is what he calls a battery equalizer. He's presented at FMCA
conventions.

Gordon (Tin Gerbal) GMCer up in BC really knows his way around those things. You might send him a note.
The trick is to hit the battery with a high voltage of 50 to 100us. repetitively. I think the repeat rate is around once every 1000us. This to breaks up the accumulated sulfate and causes it to go back into the acid solution.
I've got one around here that I built many years ago and have had some success with it. Completely shorted cells are difficult to open up again. I have only been about 50% successful on them.
I'm sorry but I do not have the plans for the one I built any more. This one is similar to the one I built.

Here is another site to look at:
http://www.inthelight.co.nz/techo/desulphator.htm
Be careful buying these off of Ebay. Most of the cheap commercially available ones are really nothing more than a trickle charger or 2 stage trickle chargers.
There are also people offering chemical desulfators meaning add my magic potion to your battery and it will fix or prevent your problems. I have never seen these work but you will find lots of endorsements saying that they do. I'll stop just short of saying these are a scam. I do not know this for sure but I have never seen anyone recover a battery with these.

Mainly sponsored by Good Sam and Camping World. They had some interesting
seminars that are "generic" in nature. A daily "Passport" was $69 which
included the parking. As you know, at the KFEC that's $5 per day. It took up
all of the South Wing and half of the East Wing. People attending were glad
we have such a large area under air conditioning. Because of the heat, the
officials allowed generators to run longer for those in RVs. RVs were parked
at KFEC and at Cardinal Stadium.

I tend to agree with you. If the snake oil really worked, some major brands
would carry it. But, if it helps you believe, so be it. The guy that
presented has been doing it for years. Apparently he does a good job with
battery maintenance guidelines regardless of the magic additive.
By the way, when asked if he had any data to back up his claims he changed
direction somewhat, just like a good politician.

I repair electric wheelchairs and scooters the problem of sulfated and neglected batteries is a big factor when I get them. A wheelchair or mobility scooter batteries cost me $150 a pair. I have built desulfators and used two kinds of chemical none worked good enough that I could sell the batteries. I talked to a warehouse friend who is responsible for many maybe 30 electric fork lifts. Their batteries cost thousands and they tried many tricks to revitalize the battery banks and found nothing that really brought them back to a satisfactory level. Just my experiences.

Our local Costco doesn't carry the golf cart batteries, but Sam's Club seems to have plenty in stock.

My Sams Club batteries are 7 years old and going strong. I do keep them on a battery maintainer when I'm not using the coach.

For some reason not all Costco stores carry golf cart batteries. I did just find them at the Missoula store for $77 each. Trojan T 105's were $134 at a commercial battery store. My last T 105's ran 11 years in RV service, 10 of them with a buzz box converter/charger. I wanted more Trojans, but the price difference was too great.
I now have a PD converter/charger with charge wizard, and in 10 more years I will tell you how the Costco one have held up. Well, I hope I hold up 10 more years. My 36 year old Travel Trailer will be 46 years old by then, and we may all go out in a blaze of glory.

If anyone knows of a Costco in the Bay Area that carries 6 volt deep cycle batteries please let me know. Or is there a fair deal elsewhere?

Gary - I've had good luck with a "Battery Minder" brand charger. It has kept the M/C batteries and the Vette battery lasting 3-4 years longer than they used to. It took a battery that would not hold a charge or start one of my cars and restored it. It can take a LOOONG time to bring back a badly sulfated battery. It works better to prevent sulfation when used as a maintenance charger. Just my experience. I agree with the comment that the liquids would be more readily available if they really worked.

My brother brought an inboard boat to my place about 9 years ago in it was an 800 or so amp hour 12 volt battery that he had bought years earlier and never used. It was dead as a door nail.
I hooked it up to a 20 amp battery charger for about a week but it wouldn't take a charge. I then hooked it up to my motor home + 40 smart charger and checked it a few days later and damned if the thing had charged up. That battery lasted another 8 years starting a 460 ford boat motor.

That's the one I have. However the Schumacher mentioned looks interesting. However the small battery minder does not take up any room, but will not do 6V batteries.

I was looking around the net and came across the following regarding desulfated batteries. Besides desulfating, it addresses the gassing or misting and corrosion problems with wet cell batteries. There are more pages than just these two to read and watch video. End result my house (dual trojan 6v) don't seem to hold charge as long as they once did and at the price listed I think I'm going to tryout both products and will report back.
Here's the links and wonder if anyone else has had any experience with them.
