    12volt battery vent? If replacing with aftermarket 12volt there are no provisions for it.

    You DO have a vent line connected to your battery, don't you? There's a good reason why hydrogen should not build up inside the car.

    there are provisions for a vent if you purchase the correct aftermarket battery

    There are very good reasons why you want to vent any battery in the passenger compartment, but they all have to do with the safety of humans, not with the performance of the battery.

    While the chances of a battery being so severely overcharged, that it vents toxic & flammable fumes, is remote, it is still possible. For that reason, we recommend any battery installed in an enclosed area (including trunks and interiors) be properly-vented to the outside atmosphere. The Optima DS46B24R YellowTop does have a vent port for hose attachment.

    I've got an Optima Yellow Top, and it's got the vent port.
