I have purchased two smart but economically priced smart chargers for $60 each- Power Runner by Shim Fu -automatic 2/6/10/12/15amp with a maintenance desulfating pulse generator)The direction claim the desulfating cycle is limited to 18 hours then shuts down ,however 39 hours later both are still going thru the pulse cycle.
I am guessing that it is due to the 8 D battery size and it is smart enough to know. Does anyone that has a lot of real knowledge about desulfating think I should shut it down and charge up the desulfated area then continue the pulse cycle for best results or let it run till it automatically stops and then recharge the desulfated plates??? Which way will give the best results for desulphating??????? Yes I did charge to maximum before running this desulfating maintenance cycle.
Had no luck with the factory techs as they do not speak English and as usual with the reps at the importers they can only tell you that you want to buy there product, not anything about there product.
On a related note, I am considering buying more of these to give each house battery (when I buy them) it's own permanent charger on even know the maximum is only 15 amps. Still haven't settled on AGM or Flooded lead acid. I know they would be worth buying with Flooded lead acid, even if they are a little small (I have a large 24 VDC engine driven auxiliary generator for bulk charge when away from shore power). The notion is that each battery would have it's own tailored charger and pulse generator .
If I decide to go with AGM batteries (better for large amp fast bulk charging with my Auxiliary 24 VDC generator) will they benefit or be harmed with pulse desulfating with the maintenance cycle on these little smart chargers?
My power converters consist of a mix match of several small models with no charger and one 2200 watt UPS (from a older office computer backup)and I do not think it has a very large charger with it's small bank of (old gel cell, I believe)24 VDC batteries so I was thinking it simplest to disable this charger feature and just use the inverter as long as it can be done. Some day I do intend to go with a Outback or Xantrex but trying to cut corners for now and use what I have. |

Here's the page to spend an evening with, you'll come away knowing a lot more about your batteries...
http://www.uuhome.de/william.darden This guy is really informative. A bit on desulphation and a Lot on general stuff we all might want to know.
For more info specifically on desulphation, hang around this page: http://www.shaka.com/~kalepa/desulf.htm
On this page are links that will take you to more than you probably ever wanted to know about desulphation.
One thing that I can tell you for sure, is that the true pulse-desulphators seem to need much more time than 18 hours if you're trying to reclaim a dead battery. Depending on the type of sulphation and how much there is in the battery, it's possible that a true desulphator can run for months at a time to do its job.
And another thing is that due to the way true pulse desulphators work, they won't work with jumper leads or battery clips.
Without getting into electronica minutia, a simple explanation is that they need to be connected very intimately with the battery and due to lead inductance, the leads must be short,thick and well attached to the battery posts or the "pulses" will get lost before they even make it to the battery.
There is a lot of tech in proper pulse desulphation, and there is a lot of hype, and most unfortunately there are products out there that claim to do the job that absolutely don't.
Best of luck you ya!! |

From what I have read and heard, The desulphator unit must be the "only" thing hooked to the battery during the process. (by itself only).
That usually means unhook all other wires, feeds and cables. The pulses can attain rather high peaks during the cycles and can damage other stuff left hooked up or the other stuff can kill the desulphate effects before it can take place.
I spent some serious money trying to desulphate batteries ( and wasted most of it too! ). I could have bought new batteries for the same money.... |

Truthhunter, I think you ought to figure on a month for effective desulfation. It's best to make sure that nothing besides the desulfator is connected to the battery being treated.
Good luck!
