I know it'* been done a few times, but i'm actually not asking for help on selection. What i am curious about is options we may have. After starting to clean around for any corroded connections back there, i noticed that the battery vent hose is awfully cramped due to the size (width) of the battery. Coinciding with the bay the battery sits in, i was wondering if there is a better sized option for our cars out there? It seems like the vent hose should be more taut than it is what with catching on the side posts as well as the arch it creates due to the narrowness of the standard battery.

Of note: i seem to be having some moisture at almost every junction of the vent hose - the 'T' joiner, the elbows. And i understand i shouldn't be having any moisture there. The hose looks to be in extremely good shape other than this moisture at the seals. Could this be a sign of a clogged hose? Bad battery? Or does the hose in fact need replacing? The battery is the Duralast Gold meant for the Bonne and is only about a year and a half/20,000 miles old.

some gassing is normal when batteries get warm or used thus the vent hose. as long as it isnt excessive to the point of the levels going down significantly dont worry about it. unless the hose is kinked to the point of not being able to pass water or your car starts cranking slow i wouldnt worry about replacement
