Totoo ba maka extend ng car battery life ang Battery Desulfator?

[Chinoi]

Actually nakakalito nga. Ang daming version ang mga circuits ng desulfator sa Internet.

Since curious lang ako at available naman yun mga components sa junk computer PSU ko sa shop. Gaya ng power mosfet, Iron Powder Toroid Core for noise filter, Ferrite Toroid Core for higher current pulser at fast recovery diodes at mga Low ESR capacitors. Prototype board na lang kulang at NE555 IC na abot lang P40 lang. Yun mga wires ay pwede ko kunin sa mga wires ng PSU.

Balita ko na lang kung totoo.

Mahirap lang visually ma-confirm kung effective na mabawasan yun mga sulfate since sarado o sealed ng yun maintenance free battery ko. Try ko na lang sa mga Battery shop dito sa amin.

Ito pala napulot ko mga spare parts para Desulfator. Wala kasi mabili na mga Toroids sa Raon.

Update mo kami sir pag natapos.

kaya lang para ma-prove na nakakatulong nga para mag extend ang life ng battery mo, you would need a control battery at ung test battery.

[Chinoi]

Hindi ko yata nabasa about control battery. Para ba sa comparison iyan?

Ang attempt ko lang extend yun battery na talagang ginagamit malapit na matapos yun warranty period. Di ako mag attempt magbuhay ng dead battery or shorted na mga plates. Dahil impossible talaga ito.

how much ang battery desulfator?

Around $15-$20 yun nasa internet. Pero para sa mga Low capacity battery ito.

Mas mahal syempre yun para sa mga Car Battery dahil high capacity mga malaking toroids cores at Mosfet nito at wire size gamit dito.

Kaya siguro marami nagsasabi na di gumagana ang battery desulfator ay dahil maling capacity ng desulfator nabili nila or na-diy build nila.

Tagal ko na sa field ng Electronics at Computer at di pa ako naka pag try mag build nito. Naka design at build na ko ng multiple cdis ignition para sa kotse ko at na prove ko na effective talaga ito.

Car Battery Desulfator naman next project ko para ma prove ko personally kung totoo effective nga ito.

for comparison po sana

chinoi, palagay ko, effective ang desulfator. depende sa laki ng spike at freq. some use 1k pulse, others as high as 3khz. nadiscover ni dr. vogel na ang freq ng quartz xtal (at water din) ay 454.

the good desulfators cost more than 150usd. for the small ones, less than a hundred. since you are an experimenter, i suggest you concentrate on 454, since mga crystals din ang gusto mong alisin sa mga plates, use a 555chip at this freq and sweep it with another 555(get the sweep voltage at pin 6 or 2.)
another option is to construct a colpits oscillator using the 455kz ceramic filters found in some am radios. pass it thru a series of decade counters until you bring the 455kz ceramic filters down to 455hz. A small trimmer cap could bring it down to 454. i've seen some circuits using pwm with the 555ic on pwm mode with variable/adjustable duty cycle.

personally, i would prefer to use 454hz since this freq is a valid quartz freq. it would be fun to try to experiment again with this technology. they say that there are millions of desulfators around the world built by avid experimenters with circuits from the web, gratis?

on word of caution, though, because of the high amplitude pulse output of some desulfators which is more than 100v pulse (peak), it would be wise to install an LC low pass filter in series with the wires feeding the sensitive electronics devices like sound systems, etc.. it is also good to install low voltage mov's or zeners on this wires. if i were you, i will not use the desulfator on the car but on the bench. happy experimenting!

Cguro unahin ko mua yun 1khz frequency using toroid core inductors. Mag assemble muna ako ng Inductance Meter to measure yun mga inductance ng Ferrite Inductors na i-rewind ko.

If I remember right. Yun 455khz ay yun frequency ng am radio IF stage circuit. Probably gawa na lang ako ng NE555 na may frequency na 454 hertz para mas simple.

You are right, bro, IF freq. If you use a 555, pwede mo ring i-sweep ang freq by another freq from pin 6 and 2. Palagay ko, uunahin mo ang variable/adjustable 555, ano? Medyo advanced ang setup ko dito dahil may scope, HP LRC bridge, 1ghz freq meter, and HP 1 mhz sine oscillator. May Bird swr meter pa nga
ako dahil radio communications/repeaters ang forte ko.

I understand that a car battery could be desulphated in 2-3 weeks. Do you know that a TENS (nerve stimulator used by physical therapists) output is 150-200v p-p? When you measure this with a multitester, the reading will be around 6v. Only a scope could read p-p readings.This is enough to cause havoc on modern cars electronics.

Battery desulfating shops could be established in your vicinity to 'wake up' sleeping batteries, like battery life extenders. L2L
