Battery pulser - PeachParts Mercedes-Benz Forum

Is anyone using one of these battery pulsers to prevent/desulphate the lead plates of their car battery? I understand these devices to a great job to keep the battery vital.

Thanks,
V.

i understand that these devices strip the lead sulphate from the plates[which is the cause of diminished capacity in a battery].

These devices are mainly for sulphate prevention. They can only remove minimal sulphate once it has built up. All it does is charge up to some voltage (in my case 13.5) and then let the battery float down .1V and then repeat. I have one on some batteries I have for standby power. I have not had it long enough to know (check back in 5 or 10 years...). However, it is only for batteries kept on long term storage. A starting battery in normal use in a car doesn't need it. And if you had a battery sitting around for a long time it probably wont help it.

Not a voltage pulse, but -as I understand it- it sends every 30 seconds a 90Amp pulse of 100 micro seconds into a the battery. Reviews are very positive.

I looked at that link. It looks interesting. I do not know how it compares to the one I have from VDC electronics (BatteryMinder). I am not sure I explained exactly how mine works, only what I observed on my DVM. I will put my scope on it and see if there is anything else going on. As far as voltage vs. current, to get a current pulse into a battery you will need voltage. Voltage is the pressure and current is the flow. So a voltage pulse will result in a current pulse. It is interesting that they do not sell this in the US apparently. Perhaps it is blocked by an existing patent? Anyway, on the one hand they state that prevention is best, but they also have a document purportedly from University of Vienna that says you can fix bad batteries to some extent. Still it is true that a good battery in normal car service will not need this. I personally would not waste time trying to rehab old batteries unless they were very valuable and only "slightly" bad.

The labtests & testimonials claim it extends battery life substantially aswell as keep battery power at maximum at all times. For 20 Euro's/Dollars, that's not bad. I'm sure these devices are sold under local brandnames in the US.
