I fall from the faith. have a brand new baterie of HD in my thick inside. she has done wonderful her job. now the box has stood 2 weeks, ignition was off and closed. wanted yesterday evening to turn a round and… nixx…. dead, only a glimmer of the dashboard… no jerk… so ctec baterie trainer on it… and. well that’s not right, the LED on the charger was totally weak, well, let the night turn. then this morning before work in the garage and ignition, starter button… and??? NIX baterie dead…. no jerk. how does that work? is inexplicable to me.
