    I have to look through your video library and see whether there are videos about batteries. For the life of me, I don't know how to care for car batteries….and whether some of them can be rejuvenated.
    tHanks for the fun video

    There not very well made a lot of the lower end electronics have cold solders joints so that another thing to watch out for.. try to reflow the solder and see what it does

    Bought cheap 12V – 1 AMP battery maintainer from Walmart for $10 last year. Really tiny.
    Has 3 LEDS – Green (Charged) , Yellow ( Charging), Red (Error)
    Hooked to my idle Truck battery for a year. I just started the truck without any problems.
    Every time I checked the charger was in the Green ( charged ) state.

    It would have been interesting to show us how the device works by a quick walk-through of the schematic. It would have fleshed out the video and give us newbies an idea of how these circuits work. Why a DC to DC converter when it's already DC? LOL

    Amazing for the price. You couldn't buy the parts for that much.
