One day, when I have accomplished pulses of three or more figures, which deliver (perhaps) tens of Amps, in a very narrow pulse, I would be very interested in testing the difference in terms of the time it takes to desulphate a lead/acid battery.
In order to at least approach triple figures per second I think I am goint to have to temporarily abandon using those MOSFETS I harp on-and-on-and-on about. Without proper drivers I am taking too many chances, and besides, I feel more comfortable using brute current strength for driving semiconductors, and I still have some functioning sturdy-looking transistors which should be able to be hacked together and deliver at least a 'hum.'
... And then there are those (presently) rather mysterious thyristors, SCRs and TRIACs. Lots of experimenting to go, and the stacks of old circuit boards I have collected still contain interesting components just waiting for a new life (Even if that life is likely to be rather short if I know my handiwork).
My most successful desulphator is pulsing at about 6 PPs through a transistor driven by a relay. I just plug it in, and leave it for a week basically.
Of course during the interim period I continually observe the SG, electrolyte levels, voltage, bubbling, colour of plates & electrolyte, the degree of obvious 'wear' on the plates etc... .
* I fix my friends' batteries, but so far I have had no success trying to get commercial businesses to try what I can now do.
* I have handed some samples to people as proof the system works, but they seem to have just used the batteries and forgotten about them as they worked fine.
- Anyway, it's early days still, and as time goes on I can become more proficient and confident for the time when I really am taken-notice of.
* An acquaintance 'introduced' me to a local group of fishermen. They use boats which often use the 130 A/H batts in a 24 Volt set-up. These people depend on their batteries for their livelihoods, and possibly their lives in some situations at sea. The concensus from this group was that they were very wary of batteries which have been rejuvenated, and believe only new batteries can answer their requirements.
* What I'd like to do with this group is firstly to get their batteries properly charged so they'll last longer than the usual two-or-so years they usually do, then arrange systems to help maintain their state of charge while sitting idle at the quay (solar panels for one), and also during this time I'd be progressively rejuvenating the batteries they've got in storage which aren't up to par. - And to clealy label those batts which are not able to be rejuvenated for whatever reason.
The longer I do this the more sorry I feel for those who are wasting their money on batteries which will soon end up ruined due to the same mistakes regarding maintenance.
Raring to go! ..............
