Thread: odyssey pc680

i have this battery mounted in my trunk, only been few weeks. Now i can smell like a sulfur smell coming from it, it something wrong with it or do i need to vent it more?

Same thing happend to me. You got a bad battery. Mine was brand new and would heat up and smell but I was 100% sure it wasnt a short anywhere. Turned out to just be a bad battery. My terminals on that bad battery also just spun instead of staying still like they should. Swapped it out for a new one and everything is good.
