Battery desulfators

[Mickey]

I'm sure all of us have experienced what we thought was premature battery failure at one time or another. One of the prime causes of LA batteries premature failure is sulfation. There are electronic devises that are said and reports say they can remove the sulfation and return the battery a much higher level of performance.

I bought a pair off e-bay last month & they've been working away for 3.5 weeks. One battery is 2 yrs old & the other 6. The older battery was WAY down on water. On a recent camping trip, pulling out 30A and voltage was indication 2/3 discharged. Test yesterday I pulled out 50A @ a 10A rate. At end of test, voltage reading indicated batteries are at a 75% charged level. That's almost 100% of what a new size 27 batttery deep discharge battery is rated at.

Presently, I'm thinking money well spent.

that's interesting, can you post a web site on what you bought?

[Russ Chastain]

Yeah, details please. How much did you spend to get these results?

I know of two ways to de-sulfate the batteries.
One uses the charger to boil the liquid which makes the sulfate return to the solution.
I had one of those chargers on our boat. It worked very well.
The other uses high frequency voltage to vibrate the sulfate making it come off the plates and return to the solution. Like those toothbrushes that vibrate at a high rate.
My portable charger has the high frequency setting to return the sulfate to the solution.
I have rescued several batteries with the portable charger. Motorcycle batteries several times and our neighbors deep cycle rv batteries also.

What I purchased is called the wizbangplus & they have a web site. They also sale them on e-bay a little cheaper than their own site. I paid $25/ea. Qlty of workmanship and components are top notch. G10 pcb and most of the components surface mount and power handling components, through hole. The design like most of the commercial units are from a design placed in public domain in 2000.

If you want to learn more about sulfation and these desulfators, do a search there is a lot of info available.

While boosting voltage periodically can help, I think the consensus is the high freq pulse designs is more effective.

The voltage boost approach is what one find on converters like PD with the Charge Wizard. I have one mounted in the MH. MH is connected to shore power for more than 90% of the time and the addition to the pulse desulfator had shown major improvements.

[Russ Chastain]

Are you saying that the Charge Wizard includes a version of this desulfator thing (which I don't remember ever knowing about)?

[Mickey]

Nope. Charge Wizard just bumps up the voltage for I think 15 min once a day. Insures all cells have received a full charge and the "boiling" sturs up the electrolyte.

[Russ Chastain]

Hmmm.

I don't understand all I know about this stuff. But it seems like these could be real handy things. I just think they ought to cost $5 apiece.
