I had a "Super Crank" battery in my Jeep for ~6 months. I just returned it today for spewing acid out of the vent holes. Hopefully, I washed all the acid off of the inside of the engine bay. Has anyone else experienced similar issues with these batteries? I even thought it was cheap when I first bought it (not even a carrying handle??) but whatever. They exchanged it with an Energizer for free (since they didn't carry the Super Crank ones anymore).
