The little Genius is brilliant
I have an older Jaguar sedan with a maze of electronic systems and monitors that deplete the battery in very short order when the car sits for extended periods. When the battery finally goes dead, the "brains" of the vehicle go stupid and getting things back to normal is a chore. To test the little 2 amp NOCO, I installed it after a one month storage period. The battery was at 12.1 volts when I plugged in the charger. Roughly 24 hours later, the blinking red charge light changed to green and has stayed in "float" mode ever since. The permanent install design of the Genius 2D is exactly what the doctor ordered if you leave your vehicle in a temporary storage mode for extended periods. Apparently it's in high demand or production has been interrupted, as I had some difficulty finding one at the retail price. fixed me up and got it to me in short order. Thanks.
