The idea here is to send VERY short (or narrow) spikes of higher-than-normal voltage into the battery at frequencies of 100 kilohertz to 6 megahertz. (None of the circuits I have seen go above about 100 kilohertz, but some manufacturers claim theirs goes way higher). These spikes cause the buildup on the plates to dissolve - or so they say.

The voltages sent to the battery are in the 35 to 65 volt range depending on what product you buy.

Speaking as one who has earned a living repairing electronic equipment for 29 years:

You guys can do whatever you want to, to your cars. You can leave one of these things hooked to your car all winter if you want to. (You can even burn 87 octane gas!)

But NO WAY IN HELL would I hook up something sending 35 or more volts of high frequency pulses into my battery while it is connected to my car's engine control unit, body control module, skreem.... etc.

EVEN IF someone can come up with something from Mercedes that states that the electronics in the car was designed to withstand something like this, I would not connect it to my car. (And I'd REALLY like to see someone come up with such a document).

If the electronics in our cars were designed so tough as to handle something like THIS, why are there so many posts about failed modules and failed electronics?
