I had a battery installed at Firestone (I think it is an Interstate) in early 2013 - good price good battery -- seems stronger than the original battery. This week I installed the hardtop -- the lights and the defroster did not work on the hardtop (however, the small push button vanity lights in the rear of the top did work). Took it to the dealership for review -- the programming had been lost (and they blamed it on the aftermarket battery) -- I don't know if that was the cause - but reprogramming was not cheap!

I am sure, however, that if I had put in a BMW battery at the dealership and the same thing had happened the dealer would have told me that there was some other cause. One of those things that you will never truly know what happened. Although -- this does conform to the earlier post that aftermarket batteries can cause electrical gremlins!

On the later models yes. I don't believe it on these... too many people have gone w/aftermarket with success. That's dealer BS, or they are thinking of the later model BMWs. You do have to make sure it's for VERTs, not just a standard E46.

My current battery lasted 5 years & 9 months. Not bad considering the strain a vert battery undergoes. It became run down from sitting a couple of weeks. I didn't feel like jumping it & a couple of weeks later it was just dead. I did not feel like jumping it & than since i'm putting it away for the winter next month I didn't want to have to deal with it in the spring when i'm ready to take it out.

I purchased the Autozone group 94. $165.00, it has the hole for the vent tube. It took me 20 mins to swap out the old battery & install the new one. It's a simple procedure that only requires one tool for all 3 bolts.

I keep reading the verts have a different battery but RealOEM shows the same part# for a coupe and a vert...I went to Advance Auto and there was no difference for coupe/vert .....I found a EverStart Maxx H7 at Walmart for $139 but I see you guys are buying 94R in this thread so now I'm confused.

I also did the Walmart H7 for $139 in my ragtop, and it works great! It is the exact same size as the OEM, and has the external vent tube also. Easy changeout--hook up a jumper battery to the terminals under the hood when you do it and you won't lose any settings on the radio, etc.

I learn more about this each week. I think that coupes and verts use the same battery, BUT the popular old "Group 49" affordable alternative that coupe guys were using just doesn't fit in a vert the same way.

Not sure why, but they changed the designation for the battery size about a year ago. The H7 is the replacement for the 94R. They're the same battery size.

(Incidently, I got the Walmart EverStart to replace my old battery, though back then it was only $105. It does fine.)

If I put my battery charger on under the hood (positive to positve, negative to ground), this will avoid losing the settings? It's not a huge deal, really.

My 330 cabriolet went *click click click* yesterday when I was getting ready to head out to a friend's for Christmas dinner. The battery charger charged it up in about 20 minutes so she'd start. A 25 minute drive both ways, she kicked off fine last night and again this morning.

I'm living on borrowed time. The stealership quoted $251.99 (before BMWCCA discount) with me installing it. Don't really want to know what they would charge with labor added.

My fave shopped quoted $300 (included tax and "labor"). Must be the $250 OEM battery.

Thanks to y'all, I'm off to Autozone for the Duralast Gold 94R-DLG.

I'll install it when I get home.

It worked like a champ. cityjohn posted the memory saver that uses a 9v and plugs into the lighter. I had the charger already and it was out from the recharge Christmas day so I used it.

Results:
1) After tax, my Duralast 94R-GLD ran about $183 from Autozone
2) The vent plug was not hard to do, just a little problem solving
3) Easy to do with decent advice for the novice
4) UnBreakable's advice about order of operation - awesome - getting shocked sucks
5) Took 15-20 minutes
6) The spanner wrench in the tool kit was a perfect fit - duh, right?

I figure I saved $115 over having my fave local shop install an OEM battery - $300 quote including parts & labor - ouch, right? The dealership parts department wanted $251 for just the oem battery before my BMW CCA 15% discount (~$215 before adding back TN 9.25% tax) - about a $50 savings at the end of it.

I saved enough cashola for at least 1-2 sets of oil change materials depending upon which scenario I choose on savings. That's the next deal I get to learn in 1500 miles. I bet there's a thread on that, too.

Thanks!!

I think you meant 15,000 miles but you probably need to change the oil between 7500 and 10,000 miles like most of us do. Read some of the threads about oil change intervals and you will probably agree. Alot of good info on this forum since it sounds like you're serious about DIY maintenance. Welcome to the forum!

Actually, my soon-to-be-ex is a real nut about oil changes and maintenance. I've come to agree with the view. Keeping the basics up and in check means that preventable stuff at bay, for the most part. Freaky stuff happens. He was persistent about changing the oil every 5000 miles. I pick up the supplies at the stealership with my CCA 15% discount - it's actually competitive from them compared to "out in town".

I've got 93,500 miles on my 2003 E46 cabriolet. It had just under 8,000 miles on it when I bought it in 2005.

She's starting to burn a bit of oil that's noticeable. About 3500 miles after an oil change, the light pops on so I top her off. My local shop (not the stealership) asked if I was burning any oil. She's not leaking it.... yet.

At 93500 miles, something will need work! That work is cheaper than a new car.

I look forward to digging around in here. Lots of good info. And it makes owning a bimmer more cost effective.

He is living in the dark ages or likes wasting money . Synthetic oil is engineered to last. Your money is better spent on oil analysis which will tell you how well your engine is performing and how long to go between oil changes.

My Ride: 2003.5 M3 vert
Thanks for the tips in this thread, I had no idea the vert had a different battery, almost bought the wrong one until I accidentally stumbled upon this. Picked up the H7 at Walmart for $149. I also realized the previous owner had installed the wrong size battery, didn't connect the vent and stuck it on top of a piece of wood and jammed some cloth on the side to stop it from sliding around. Thus my question:

Anybody know the part number for the battery tie down for en E46 convertible?
