Yep shori does not work when its cold just removed one and lead acid when back in after replacing the starter solonoid from trying to start it so many times! But the other 570 has a turn tech and it seems to start OK go figure, the bergs have really easy acess to the battery and air filter as they are under the seat, I am going to leave the shori under the heater vent in the truck then use my little jumper cables IF I still have a problem starting
