Then this morning I go to start the car, and the exact same thing... I hear a bunch of clicks, and the car won't start. I didn't get any error messages on the dash prior to this. The only odd thing I've noticed is that in the center console, only on the panel that opens up, the lights would flash on and off every so often.
I went back to try it again a while later, and now I see a red message about the brakes, and still no start

SO NO the Aux bat won't affect starting.

I am new to this forum, and learned from VettDvr about the options for the aux battery. I bought the Autozone GTX14-BS today for $81.99. The guy said the batteries just went up in the past couple of weeks. Still much better than the dealer, and saving the dough on this easy installation is nothing but fun!!Thanks guys!

Glad it worked out for you sorry the $$ went up. I paid $149 for the OE battery before I did the research on opions. What gave me the lead
was the OE battery had the name of a company in Italy that produced the battery. Then I went to their corporate website and researched the products lines they produced. From this I got ref #'s and then went into batteries sold in the US. Once I found the "key" I was able to cross to other sold in US batteries that are all produced by the same company and meet the same specs. And therefore the batteries recommend. Some of them I actually went into the stores and made a physical comparisom just to be sure.So there really is no reason not to save some $$ in this area. Unfortunately I had to pay the full $149
to get the "leads" to find the "key".
The nuts are 10mm, a socket and short extension works well.
The cabin air filter is in the A/C cover so if you haven't replaced it now's a good time to do so.
Two comments:
You'll need a trickle charger; I picked up a 1.5 charger/maintainer for $20 at WalMart
The MB Battery sticker on top is removable and can be stuck on the new battery, and positive cover fits as well, for those who want that OEM look.

What batteries are people using to replace the main battery in the trunk? I tried searching the forums, but there didn't appear to be any recommendations for replacements other than going to the dealer. I also tried using the online tool at sears.com, but it wasn't able to locate a replacement for my 2003 E320. Weird.

I had one in my Honda motorcycle for 4 years with a trickle charger and it certainly surpassed the Wal- Crap I had in other bikes. I replaced it with
another Batteries Plus AGM as well. I think they are like Sears and contract for stuff with different suppliers as time passes. My first one from them was a Yuasu. They make the best recreational type batteries on the planet (IMHOP)
I used a Bosch source for the main battery and I recommend it as well.
Anyone find this battery in Canada? given this is sunday and it's frigging windy outside, I am just doing limited search online today.
Is this the same thing? It's labelled Energizer 14-BS and the box says it's AGM.

It is pretty evident that even a 170 amp alternator is pretty marginal for these cars.
It may be that you need one or both replaced. The factory batteries are pretty high quality. I would give them another chance. Of course, if I am wrong, I won't be the one looking for jumper cables in the snow.

BUT I do park outside and it has been frigid this weekend.I don't know if the batteries are under warranty, but the stealership wants like 200 bux for diagnostics, if something is wrong and under warranty, that fee is waved. I think that is the case in all MB Canada stealerships.
Did I mention I am only about 2000km from the expiry of warranty?

If you do the work yourself, it is prudent to disconnect the positive side of the main battery before working on the smaller one. The main battery backfeeds the smaller one and unless you are extremely careful you can easily ground the small battery positive connection causing a direct short and possibly expensive repairs. There is a step by step method posted by vettdvr (sp) that will keep you straight. Battery Warranties are about as consistant as the weather. I would expect the dealer to dodge but who knows, it is worth a try.
I got about 6.5 years out of the factory battery(s) but it is a low option car in a mild climate.
