Revive a dead battery with aspirin

Comment: I've heard dropping a pain killer (asprin) into a dead car's
battery can give you enough of a jump to start the car. Any idea if this
is true?

Do they still make car batteries that aren't sealed?

The way I heard it, you drop a pellet of plutonium in. And where you're going, you don't need...roads.

That's only true on cars equipped with a flux capacitor.

It will not work. Potentially, it might revive a bad electrolyte, but I doubt that as well, but even if it did, it would not charge the battery. The aspirin has no electric charge in it.

If you don't have one in your car already, this is where you can buy one:
Flux Capacitor at KaleCoAuto.com (Other curious stuff for sale as well). Very amusing!

None of those solutions will work. The starter motor draws a lot of power (sometimes over 100 A, just look at the cable running to the starter motor) and no simple ad hoc battery design/fix will be sufficient. Even with a fresh battery, you only have enough power to crank it for a minute or two.

If I really had to start a car with a dead battery in the hypothetical example they gave, I would use the tow line to rig a pull start from the drive shaft or one of the pulleys, sling it over a sturdy branch and rig some weight to do the pull. Or just use a similar device to pull the car and start it that way.

The cited source says that asprin will work to temporarily revive a car battery. My specialized knowledge as an electrical engineer says it should work although I have not tested this.

I agree that it will give some effect, but I really doubt that it will be enough to crank the engine, or even to get the CD player going.

I happen to have several dead batteries laying around. If I have the time, I will test this. A first person test is always the best although the born sceptics here won't believe unless I come repeat the test with their car.

I don't think it's particularly far-fetched.

If the battery is in okay condition (good electrolyte, plates not badly oxidized) but fully discharged, you could bring it to full charge by pulling all the sulfate off the lead plates, re-exposing metallic lead. By doing this, you're recharging the battery chemically instead of electrically. If you could put in a chemical that would do this but not foul the electrolyte, it seems possible to restore the battery to a pretty good charge.

I don't know if aspirin will do this though.

If you do the test, I'll believe you. Come to think of it, I have a bunch of batteries somewhere as well. I don't think I have any suitable painkillers though, I prefer paracetamol. My batteries may be too dead as well, as they have frozen. I just kept them in case I need some lead some day, as they are a good source of lead.

I'll even try it on a Swedish car. One of my rally cars is a Saab.

Well, generally, civilian possession of plutonium is illegal anyway, so you're right Brad. You don't need roads in jail.
