Message Date From Subject 12263 2016-02-02 13:25:24 Sandeep Lohia OFFTOPIC, HF battery desulphate What I know is sulphate plate will act as capacitor & will by pass
high voltage HF pulse, which resists DC, thus charging, & diluting
back sulphur to lead acid battery, specific gravity have gone low, for
by mistake, I left my new Radio battery uncharged & in low voltage
stage more then a year.
will I also dilute a little Sindha Nanak ( Epsam salt) ?
I have AD9851 homebrewed DDS willing to add another home brewed BITX
IFR 510 linear amp at DDS output. & a high frequency high amp diode (
half wave rectifier) from SMPS at final output as to de-sulphate my
100 amp 12 volt battery. what about the final autotransformer of IRF
840 1:4 or 1:9 as to increase more voltage at output, hope it won't
smoke or burst...
hope resonant frequency something close to 3.5 Mhz will also melt
down hard sulphur or break them...
or the last option is giving away my power bank for recycling?
any experience expertice? negatives R also welcome!

12285 2016-02-07 12:25:50 Sandeep Lohia Re: OFFTOPIC, HF battery desulphate I just removed reservoir capacitor on secoundry of half wave 2 amp
SMPS. pretty simple job done in minutes...
thus making it a pulse charger, & it's working...

12308 2016-02-09 07:52:13 mosaicmerc Re: OFFTOPIC, HF battery desulphate Well, I have developed a professional desulphator, dedendriter and general rejuvenator for lead acid batts over the last 3 years. Processing almost 200 defunct automotive sized batts for empirical testing and developing custom algorithms requiring 7,000 lines of assembly code. It now turns over a fully discharged (sub 3V) 12V or 6V battery back to OEM compatible ratings in about a day.....at the rate of 1.5Ah per hour of recovery.
The short answer is it can work, the real answer is sometimes not and knowing how to code a state machine to decide the difference is the trick. The 3.x Mhz magic frequency is also magic smoke and mirrors. I know, I tested it all.
EPSOM salt ONLY works by improving the conductivity of the electrolyte and does little about the real lead sulphate problem. It provides more ions in solution to give the battery a little cranking amp boost (not Ah). It also degrades the battery electro chemically over the medium term and shortens its life. Ergo manufacturers never put it in 'new' batteries.
I just recovered $189USD worth of defunct AGM batteries in 3 days with one device, fully automated. They were recovered with >90% cranking amp and >60% Ah capacity. No additives.
AGMs recover the best, they don't stratify, shed paste, or develop dendrites, they also sulphate evenly which is better for recovery.
I have Brazilian private sector interest and interest from the Birla Institute in South India, and it's not
12310 2016-02-09 08:20:26 Jim Strohm Re: OFFTOPIC, HF battery desulphate Jim N6OTQOh yeah, Wes Campbell and Rick Hayward aren't famous because they have engaged in patent secrecy for the last 30 years. They're famous because they threw their remarkable ideas out into the world for others to use.You know, back in the late 1960s, noted electronics magazine journalist Don Lancaster strongly urged inventors to skip the patent process completely, take their products to market quickly, make a bunch of money before the product can get pirated, then quickly get out of that business and invent something else. Instant savings: all those patent attorney fees, all the time lost during the patent application process, all the money needed to establish product security processes. Oh yeah, and it cuts your time-to-market by about 95% so you can start making money almost instantly.I'm just one person, but my opinions echo those of probably millions of American professional technicians and dedicated do-it-yourselfers.And yes, if plans for your device were available in the public domain, I'd happily drop $200 on parts today to build one.Yes, I would buy one of your rejuvenators TODAY because I have a quarter-ton of dead UPS batteries in my shop that need replacing -- or rejuvenation.Yes, I have Chinese hand tools but I only take them out in public when my Snap-On tools would get stolen.But you know what? American based tool companies like Snap-On continue to manufacture, market, and sell hand tools at astronomical sums, even as the Chinese have finally brought their hand tool manufacturing quality up to the level of Snap-On, and their American distributors are matching Snap-On's lifetime unconditional guarantee on tools. "Buy American" still carries a whole lot of weight, at least for stuff that's not throwaway consumer electronics.Yes, the Chinese will instantly steal the design, and the Indians will steal it the day they find that they can't get the Chinese units for 17 rupees.Given that an automotive battery costs an average of USD$100, almost any shade tree mechanic in America would gladly pay $100 for one of these. Given that a pro-grade UPS costs between USD$200 and $400 to re-battery (and these are the smaller ones), a lot of small IT shops would happily pay $100.Ancel,One way to avoid the patent hassle is to release the design into the public domain simultaneously with having a top-quality product ready to ship in quantity.

12313 2016-02-09 11:15:09 Jim Strohm Re: OFFTOPIC, HF battery desulphate LOL!!
Although famous, Wes and Rick aren't rich like Croesus, Paul, and John
from what they gave us. There's a difference between copyrighted
music and copyrighted technical info. But -- if you could have dinner
with one of them, would you choose a ham or a Beatle?
I'd choose a ham, because regular pop celebrities have ceased to impress me.
12315 2016-02-09 13:04:11 John Marshall Re: OFFTOPIC, HF battery desulphate Gotta agree there, Jim. I've enjoyed dinner and conversation with hams and musicians but I'm not much interested in celebrities.
12316 2016-02-09 13:12:29 Jim Strohm Re: OFFTOPIC, HF battery desulphate Hey John
Although I can't say "when you've met one Presidential candidate
you've met them all" I think I've met 8, and only a couple impressed
me. And while my list of "celebrities I've met" is much longer than
my list of "celebrities who've impressed me," I'll say that Liz Taylor
was the most gracious of the bunch.
Anyway, back to the original topic of this massive OT thread, I know a
killer safety engineer here in Austin who can get a device through USA
safety certs faster than you can blink, and has done numerous safety
certs in numerous countries for 'lectronic gadgets that connect to
He's almost as "waay kewl" as Liz Taylor was in that swimming pool
back in '68. Such a lady...
12317 2016-02-09 13:21:54 mosaicmerc Re: OFFTOPIC, HF battery desulphate I think I need the contact of that cert' guy.
Although the DIY kit approach may be ok in most areas.
12319 2016-02-09 13:24:05 Jim Strohm Re: OFFTOPIC, HF battery desulphate I'm taking this off-list.Jim N6OTQ 12320 2016-02-09 13:28:18 mosaicmerc Re: OFFTOPIC, HF battery desulphate Jim.
I had that position until 3 weeks ago. At which time Paul Regis of the WIPO offered me a 90% rebate on patent application fees plus elevation to the PCT convention after 12 months of establishing the priority filing date. That gives me another 18 months to select which member countries to 'file' in before I have to have the patent examination. 30 months worth of patent pending. So I just need to draft the essential claims and drawings to get my priority date. The patent gives me trade-able IP if I want to license.
There was a workshop in Jan. sponsored by IPICA-project.eu which included expertise from the U. of Applied Sciences - FH Joanneum in Austria and the U of Alicante' - Spain. My battery project, called Battery Deja Vu was one of the 6 selected from the Caribbean to be supported. It was also the most ready for commercialization based on a prepaid mobile phone model.. Basically you pay minimum for the machine other than basic component costs but $4 per recovered battery via PAYPAL or http://www.boku.com/, get a 'code' and reactivate the system with a fixed set of 'good' regeneration uses, anywhere in the world.
Thus I am almost ready to deploy as a semi built 'kit' to anyone who cares to build them. I shoulder the risk as I only get paid by the use of the system, not in advance. Users have little risk.
I will share the $4 per regen. battery with distributors to keep the capital cost down.
I developed it because Trinidad, where I am from, is the smallest country in the world cited for mass lead poisoning via lead acid battery dumping & backyard smelting and we need mitigation.
The poor people who scavenge the batteries can't afford $250+ for the system, a 9" cube. But IF they get it for, say $40, with 10 'good' uses built in...it's essentially free and they WILL have the $$ to buy more uses from the sale of the first 10 regenerated batteries. A sustainable method. It costs between $0.30 to $0.60 USD in electricity per regenerated automotive sized battery depending on size and condition.
So, Jim, If you have 'ton' of batteries to recover maybe I should do an NDA with you and deploy a kit to you. I am in this for the longer haul, it's not a get rich and sell out model. I intend to spin off other versions and I may be doing a Ph.D. on the science of the recovery.
I am designing a website now and establishing a public board of advisers with traceable credentials. I just sold 20% equity (last week) to a private investor in a first round of capital raising to start manufacturing. CARIRI.COM may supply the secondary 'repayable' seed funding to get more 'kits' deployed and working, we are in talks now.
As it stands, the system is menu driven, auto sequences two batteries for regeneration with hot swapping for 24/7 ops, maintains two other regenerated 'good' 12V batteries indefinitely and can use them as backup power if the 'mains' goes out for a couple of hours as happens fairly often in the developing world. I am prepping version 2 which would be IoT ready ...with a smartphone App interface for 2017.
12322 2016-02-09 13:45:26 Jim Strohm Re: OFFTOPIC, HF battery desulphate Jim N6OTQSo -- let's see what we can do.So you know, I've got enough computing power, software, and affiliated hardware here to publish several hundred pages a month either as hardcopy or electronic deliverables, and a quarter century experience doing it for a living.I pinged my regulatory cert guy a few minutes ago. I'll ping you as soon as In hear from him.HOLY SHIT. This looks like a really hot product you've got.Dude.All I can say about what you've got is ...
I'm willing to accept NDA status on this immediately, and as long as I get a little recognition on the back end for helping with user docs, technical docs, and some marketing activity, I'm willing to work for next to nothing for now.
Yes, I'm professionally polished enough to meet the press, both on paper and on camera. I'm not as hot as Megyn Kelly any more, but I'm probably smarter.
I've got some free time in my life right now, and I'd like to use it for socially positive work like keeping lead batteries in use at their point of service, and not sending them to the lead smelter -- or worse, throwing them out into the environment.
