So I went out this morning to start the mini to go scraping and she rolled over slower than molasses in the winter. This is with a 3 month old Interstate SP40 425ca and 350cca. All connection were cleaned when I install the new battery. Read here that a battery with those specs should be fine. Five minutes on the charger and she fired right up ( stroking the heck out of the go pedal to keep her running ). Took the battery back to the Interstate dealer and it checked out fine, but did swap it out for me. Hope this helps. Not a big fan of " no starts ".
