News on battery rubber vent smell

you think?

 

agreed, maybe you should take them out for awhile and see what happens.

 

That's nuts. Cobble something out of vacuum tubes and fittings?

 

if apollo 13 could do it, so can you.

 

That article suggests that use of a regular lead-acid 12V battery is the cause of the smell. Is that advice applicable to your car?

 

No, all Prius are supposed to be equipped with AGM 12V batteries as original equipment. However, in some instances AGM batteries were not installed.

In the attached file folder, see the fourth image, bottom of page.
"The Prius auxiliary battery is a special Valve Regulated Absorbed Glass Mat (AGM) design and should NEVER be replaced with a conventional battery design."

 

I have no idea, I am not the one who authored the link you referred to in post #30. However it would be easy enough for you to rule that out by simply removing the 12V battery and letting the car's interior air out for a while.

 

I assume the GS battery in your photos is the original equipment battery, model S46B24R. That battery is supposed to be AGM.

The only way you would know for sure is to remove the warning labels on top of the battery, then remove the translucent plastic cover and the caps covering the six cells. Look into a cell. If you see fuzzy white mats between the lead plates, the battery is AGM. If you don't see those mats then the battery is of traditional design. I did this on the original equipment battery for my 2001 to prove it was AGM.

 

I don't think either of those batteries look familiar to us Prius owners in the U.S. I realize EU/UK may have different OEM parts.

 

The Bosch battery you've shown is an S4 019, which is not the correct Bosch replacement battery--the correct battery is an S4 055. This battery is pretty much the same size as OEM, but it is a flooded acid (std automotive) battery, not an AGM so I'm in agreement with what Patrick has stated above.

Have you fitted the vent elbow? The OEM elbow needs to be modified to fit as the vent hole in the Bosch is a smaller diameter. My concern would be if the smell is coming from the battery, why is it venting? In normal operation it should not vent any gases, so if it is I would be looking for the underlying problem.

If you have confirmed 100% that both batteries were venting gases, as I said above, I'd be looking for the underlying cause.

 

That is the one I meant, but they have the wrong photo, the photo shows a S4 019, which is noticeably shorter in length.

Good luck with your endeavours.
