It's a tad smaller and has nice handles in the center, so it's easier to get in an out (what rear seat?). I finally even put in that black battery hold down (which has been on the shelf since purchase in 2004) and it seems like it will hold this battery down.

From gary's fuel relay post - it sounds like that extra pink wire off the + post is not for a fuel pump relay. I'll try disconnecting it.

The SIZE 41 batteries I normally buy usually require me to cut plastic off the ends along with removing the full width up-top handle before it will fit. I might try buying a battery from Audi.

My car came without the black battery hold down or the vent hose. At least i was able to buy the hold down.

My car didn't have the hold down, vent hose or, worse, the grommet the vent tube runs through that seals the bottom of the battery box.

I grabbed the vent tube and elbow from a junkyard and fortunately the hold down and grommet are still available new. All of the C4 Audis (92-94 100, 95-97 A6) have the battery box under the rear seat and they're relatively common so they make good donors.

I completely agree with your issues with most batteries and the UrQ battery box, though- I spent a half hour recently grinding the molded brackets off the sides of my WallyMart Type 41 just so it would fit all the way into the battery box. I posted the thread below when I first got the car because I couldn't find any batteries that fit well and were vented. The net was that a size 40R would be a better fit than the 41, but I couldn't source a 40R easily so I just used the 41-4. The bracket works fine with it and I finally have the whole battery area back to spec with the hold down, vent, grommet, etc.

BTW, I'm pretty sure the ground wire is supposed to be connected to the second threaded hole further down in the battery box as opposed to sharing the bolt with the hold down. That's where mine was connected, anyway.<ul><li><a href="http://forums.audiworld.com/quattro/msgs/18534.phtml">Battery fit thread</a></li></ul>

441 915 505 hose
shorten if necessary
5X1X1850MM

I can tighten the piss out of the lower bolt without worrying about the hold down over squeezing the battery.

I didn't know that when I used them in my car, but both the hose and "angled piece" part numbers are identical (441 915 505 and 893 915 507, respectively). Might come in handy with a concourse judge some day ;-)

There are a few C4's in junkyards around here, so I should be able to grab a set or two if it would help.

I only wish I bought more parts back in 2004.

The foto looks like there is no vent nipple. How are you going to connect a vent hose to this? If there is a way to retro-fit one, I'd like to know because I have a non-vented battery in my 81 that should be vented. The battery was moved to the trunk on my 81 (closer to the fuel tank so the inevitable explosion will be louder I suppose ....).

is it just a simple matter of drilling a hole thru the case and installing a nipple? I've never taken apart a vented battery to see exactly how the 'venting' is laid out.

I found out the hard way that you don't want to take a battery that's designed to be vented and leave it plugged up. If it can't vent through the intended locations, it blows out acid in all kinds of inconvenient places.

The non-vented battery I had in there before just sat there and worried me, but it didn't try to eat the battery box ;-)

but you typically buy it from dealers by the foot. I got all excited about how cheap 5 meters of WW hose was going to be on one parts web site before they explained that the $ shown was for only 1 foot :-(

ETKA will specify the correct installed length in a "shorten to" comment for some applications (take a look at the Euro headlight washer system for instance), but others like the battery vent tube will just say 'shorten if necessary' and leave you to figure it out on your own.
