I have an optima yellow on a Civic hybrid its the same battery that uses the prius? Maybe the size fit but what about the sides plugs? + and - same side?
I contacted Exide thru the web contact form and received the following reply confirming the existence of the vent hole and the elbow. Perhaps it vents from only one side and the side you looked in is not the venting side?: Good Morning xxxxx, In response to your question below: Message: I have a question regarding Exide Edge FP-AGM51JIS for the 2010 Toyota Prius. Does this battery come have a vent hole that I can attach the Prius vent tube to? If it does have a vent hole, can it take the OEM elbow that connects the vent tube to the vent hole on the battery or does the battery come with its own elbow? Thanks. The Exide Edge FP-AGM51JIS does have a vent port. The battery does come with a vent elbow to connect to the existing vent tube. If you have any more questions feel free to let me know. Thank you Xxx Xxxxx OE Product Engineer Exide Technologies Office: xxxx Fax: xxxx
In response to my query about vent holes, the rep said all Exide Edge batteries have vent holes on both sides of the battery.
