Dead Battery Q
The kids like to leave the interior lights on in my rig (not my truck) and kill my battery. I took it in to AZ to have them test it and the guy puts it on his tester which tells him to charge it first. When he puts it on the charger the voltage is real low or something and instead of charging it he tells me that it's dead since the voltage is below 12. Isn't that what happens when you leave the lights on, the voltage drops?
I have the feeling he just wanted to sell me a battery instead of charging it and putting it back on the tester. Am I being paranoid?

For me it depends on the age of the battery, and if it will hold a charge after recharging the battery. If the electrolyte solution (acid) is still full in the battery, then I would try recharging it to 1. see if it will take a charge, and 2. if it will hold a charge.
From the websites i have looked at 12.6 is considered a fully charged battery, 12.3 is considered a half charged battery, and if you are below 12 volts then you have a discharged battery. The good sign is that you do have voltage still in the battery just not enough voltage to get the electrical systems to move current.

It depends on which guy is working. There is always a good one or two, but the rest are usually guys that know squat about fixin cars but got some AZ training and now think they're experts. This guy is one of those IMO.
I just want to know if this guy is right and I need a new battery because the voltage dropped below 12 volts. If not I'm gonna go get myself a charger and try to charge it.

Running the battery all the way down on an automotive battery more than a few times is a sure way to kill it.

Anyone ever heard of this?

If so does it work?

Typically, charging a battery keeps lead sulfate from forming in the battery. Your electrical charge comes from the reaction of lead with sulfuric acid to produce lead sulfate, water, and electrons for the current.
I dont see how this device will work accept to cause a continual loss of charge, but the statement of lead sulfate settling to the bottom of the battery is a good assumption as well as lead sulfate covering the lead plates to prevent further reaction of lead with sulfuric acid. Charging a battery only reverses the reaction so that lead sulfate on the "surface" of the lead plates return to lead and sulfuric acid. I would say that it only helps to keep the lead plates clean by the continual loss of lead sulfate to the solution by the continual discharge through the device. You would just end up with a junk battery sooner rather than later in its service life.

Also just read this website: http://searchwarp.com/swa472554-Unde...Life-Saver.htm
Which when you read it proves that it is bunk money waster. Crystals do not seperate readily under weak radio signals, you have to have energy and something for the crystals to become, in this case the lead metal and lead oxide plates. The battery charger and the altenator do a wonderful job of maintaining the battery already and are known to work.

Well there is a proven electrolysis method for separation of hydrogen and oxygen from water that uses lots of power, but the one that used the can hooked up to a vehicle's electrical system and vacuum port was nothing more than introducing water vapor into the intake helping to poison the combustion process, similar to the EGR. I had a heck of a time convincing a family member that was all it was doing.

My neighbor is a Chemistry professor. I asked him about the hydrogen deal. He says like you that it takes too much power to separate and there's no way your alternator could provide the power.
