My 11 year old daughter has started shooting steel matches with me this year.I mounted a Optima on a tiny little Pheonix arms .22 that she shoots.Talk about quick to index! The problem is every few weeks the dot dies.Removing the battery,cleaning it and the contacts brings it back,temp.It's got to be caused by corrosion between the contacts and the battery. Do any of our electrical types out there know of a chemical that will keep these low current contacts corrosion free?Thanks
