    I am building a solar panel voltage regulator to charge 12v batteries, using two 555 ICs. One is just a oscillator and the other is a monostable that I am using to vary the pulse from 0 to 99%.
    I have already built one that just regulates a steady voltage, but the manufacturers say that a battery will last longer with a PM controler, because it supposedly desulfates the battery. I wonder if this is true or BS.
    My questions are, does anyone know what frequency the manufacturers use? and what frequency would be best in your opinion and why?

    Thanks for that info.Yes, they are lead acid. My voltage regulator now is set at 13.8V. Doing that overcharge for 24 hours, would be hard to do since I use the battery power every nite, or on cloudy days.
