Recently I have begun to be able to notice some interesting things about batteries (my patients)
One thing I wanted to mention was that the cell nearest the positive terminal seems to be the one to give the most trouble.
I mean trouble as in that the SG seems to be the slowest to rise, and the one which rises the least. Perhaps enough time would let it catch up? But I suspect that the cell on the positive side, which is also usually the most physically aged according to a visual inspection, may have less S to add to the H2O because some of it is locked in with the shards and shreds of plate which may have become detached and are resting on the bottom.
I am now convinced that (as Sea Monkey and others) have mentioned, it's the current in the pulses which does the healing. So therefore the narrower the pulse at the sufficient amperage, the less time it will likely take to cure the sulphation.
But I'm now up to double figures with my pulses per sec
- and I can fix a battery of about 8o A/H in a week, so if I did the maths and worked it out, all things being equal indicates a battery could be fixed of the sulphation problem in ... er ................ the time it takes to boil the kettle for a cup of tea! No, of course not.
... So Sea Monkey:- Your multi-kilohertz pulser can do the job in what time?
