    Leran to recondition 12 Volt bateries At this link.

    Boy ! Did I mess up. I said point zero 6 volts. I meant Millie amps. Increasing the size of the plates increases the amperage.
    I hope everyone knows that there is a chemical reaction here and it will not run forever. The galvanizing will turn black and the battery will stop producing electricity.
    I am going to let the LED run 24 hours a day until it quits .

    Day #1 3/18/08 Started 1:20 PM.

    Day #12 3/30/08 Stopping test 8:30 AM.

    Salt water battery is still lighting LED, But just barely.
    It started off with 4 volts & 6 mille amps and is now down to 2.2 volts and 1.79 mille amps. And ran 24 hours a day for 12 days.

    Learned;; Each cell has a set voltage. Increase volts by wiring cells in series. Increase amps by increasing surface area of copper and Galvanized plates .

    Conclusion; Yes, In an emergency situation. One could build a salt water battery that could power an emergency radio. Recharge small rechargeable batteries. Hearing aids. Pacemakers. Etc.
    It is not a bad thing to learn how to do.

    PS; Let’s see Myth Busters screw this one up.
