Ok well I"m back. Apparently you DO need or it's highly preferable to have a battery with provision for the vent tube, since ALL batteries, sealed or not, vent hydrogen gas etc. I got the autozone 49D, which is a direct replacement of the stock one, and has the vent tube which I ran thru the grommet in the floor. My stock battery vent tube was missing, thank god it didn't leak acid everywhere. The autozone 49D has a 7 yr warranty and was only $59. Thanks to rick miley pointing out PE Haiges' posts regarding this autozone battery. I reset the code and I'm set for another 5 yrs.
