Interstate Mega-Tron Plus - does it have a vent hose?
 

I hate unvented batteries - they can spill and eat up nearby sheet metal. Does the MTP-91 have a sealed top with a vent hose like the oem battery?

If not, is there another choice other than an orange top Optima or the Audi dealer for a spill-proof battery? I really want one that will mount in the existing holes without needing straps or shoelaces or something to hold it down.

Thanks. 2000 A4 1.8T
