that battery is still available.
The battery is still available, but the service replacement is not the same as the factory version.
Factory version has the small electrolyte float on it, while the service replacements that I've seen do not have that.
Same battery was used in my 2003 Cobra. Thought about stashing the original in a corner of the garage, but that seemed a touch "hoarder", so I turned it in. I'll let the next owner worry about putting it back to "concours factory thoroughbred original correctliness" ;-)
