By the way, I cant seem to find a source for the siren batteries. I want to check availability and price before I decide on a new siren or not. If the batteries aren't too bad, I will try a repair. Any help on a source? BTW the amazon seller had some comments that it wouldn't work in a Crossfire June 2019. A Crossfire owner said it worked in June 2018. Does anyone know for sure? Thanks. Thanks for the links.
