[ARC5] Batteries That Do Not Corrode?

Oh, I'm sure that modern materials can beat most of the old stuff.  My point, though somewhat tongue in cheek, was that there was really nothing new in the "new" name.

    Hi Wayne:
    
    Not quite.  Modern batteries, like Ever Ready/Energizer, are much    better than prior designs.
    In 1991 the EU banned Mercury in products.  This immediately showed    up as a ban of Mercury batteries ( all the military batteries with    model numbers of BA-1000 to BA-1999) plus civilian Mercury    batteries.

    But . . . Mercury was also used on the carbon rod of the Carbon-Zonc    battery as a depolarizer and it took a lot of work to replace that.     
    Modern batteries have much lower internal resistance, i.e. they can    supply much higher currents (Flash Amps) than the older chemistries.

    There's a YouTube video showing that if you connect a series string    of AA cells (maybe 10 of them?) and put that in parallel with a dead    car battery for a few minutes, you can start the car.

What's old is made to seem new. Yet again.

          Thanks,
          
          So it's all hype and slight of hand from Madison Avenue.
