Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi: Cold waether, time for new battery. I searched the various thread and think I might get an Interstate MTP 91 battery (no track so no real need for gel). Question is the dealer selling it tells me I do not need a venting tube as it is sealed. This seems contrary to some of the posts. I know nothing about batteries. Can someone help? Thanks.

POST 2 / ORIGINAL POSTEROriginal post

You all know I meant "weather"!

POST 3Original post

There is a vent tube on the battery. I believe it exhausts the battery vapors to the outside so they don't enter the cabin. Really easy to find a battery with a vent tube. I bought one at Costco recently, which seems to be the same as ones sold under a bunch of brand names for about $56. I bought a lighter plug 9 volt battery maintainer for $10. Very easy to change the battery.

POST 5Original post

I also have an MTP-91. Good choice...no problems

POST 6Original post

I think the vent connector is hidden under the edge of the top battery label.

POST 7 / ORIGINAL POSTEROriginal post

Thanks guys. Confirms that you should never trust people that are not familiar with our cars. FYI, I found the following link that was very useful. Just thought I would post in case anyone has issues and searches this thread. http://www.industryfigure.com/berkel...he/battery.htm

POST 8Original post

ML, I have the same battery and can confirm that it has a vent port. I called Interstate and they sent the correct rubber tube for free. Andreas
