Thanks for that info. I don't know if the diesel came with the SBC braking. If it does, are you concerned with the possibility of the SBC pump warranty not being valid because of not using the right battery? My experience with Mercedes is that they would welcome the opportunity to void a warranty.

 

Should be no problem as long as the amps are adequate (same as OEM battery). Volts and amps are the same regardless of what produces them.

 

Last summer, I was getting the convenience features tirned off thing off/on fairly often. The car sat in storage all winter and when I started driving it again this spring, I was expecting to get the convenience features off messages again. Instead, not one message from April until today. Zip. Nada. Original batteries are still in place (now almost 6 years old). Both were are battery maintainers all winter.

I don't get it.

But I am happy.

I just spoke with MB and they quoted me 290 for the auxillary and 320 for the rear main battery......smh

 

I bought a main battery from the dealer last year and, with the diagnosis, it was just a touch above $400. I could not find a source for a replacement battery from anyone else in the area, and it was getting too cold to mess around.

 

I bought an Identical Gel Cell replacement from Carquest for $199. You might check there next time.

 

Sears has an AGM Group 49 900CCA 150RC for $175.

 

Genuine auxiliary battery for under $50

Does NOT claim to be an AGM battery and, at that price, I STRONGLY doubt that it is. This is probably just a common sealed lead-acid battery and not a direct replacement for the original AGM battery. I think you can get an AGM in this size for $100, but you have to hunt for it. I got one on eBay last year (shipped with electrolyte in a separate container, which is what you want...indefinite shelf life).

If it was an AGM, they would point that out in the ad...it is a BIG selling point.

I hear there is no Santa Claus, either.

 

The info does state lead acid, which is why it can't be shipped. Also, wrong size and wrong terminals.

Here's a Deka AGM, $72.00 shipped : http://www.bohannonbattery.com/html/deka/etx14.html

Edit: What's that about Santa? You better be kidding!

 

My 04 E320's secondary battery looks nothing like the AGM battery links posted earlier. I am still on my original batteries (9 years since production date). I have filled the secondary battery with distilled water twice over the last 9 years. It is still testing at 100%.

The battery in the above link looks to be the correct size. When it is time to change the secondary battery, I will buy one like the above link (probably from where a buy my motorcycle batteries) and get an AGM so that I don't have to worry about filling it with water every couple of years. As far as the main AGM battery, I will probably try to get as close to the original one as possible. I can't believe that I have had these two batteries for just over 9 years now and they are still cranking and testing just fine!!!!

That Deka is a lead acid battery, too.

AGM batteries ARE lead acid batteries, they just have fiberglass porous mats to separate the lead plates and immobilize the electrolyte to make them essentially spill proof vs. conventional flooded lead acid batteries.

And yeah, I have it on good authority that there ain't no Santy Claus. I have also heard troubling rumors about the Easter Bunny.

 

Got the main battery from the dealer for $140 plus tax.

 

If that's the white battery, it's not AGM, and that's the going price.

For those of you that want the Fiamm, oem aux battery : @ $159 delivered :

@nopcbs, Of course you're correct, however, common usage of "lead acid" batteries is generally accepted as non AGM.

You're killing me here, no Easter Bunny either.....a few weeks away and now I'm devasted !!

 

I gave up trying to expain this. For those that don't believe they can spend more, for those that do they can save $$. Mine was a sealed AGM but bought at low cost. I had to add the electrolite, leave it open 8 hrs to vent, charge up then put caps on to seal. The instructions clearly showed how to seal up the agm battery after following procedure then stated service not needed do not open.

It cost me about $65 + tax at autozone.

 

Black, not white. Part number 005 541 10 01 not 000 982 33 08

 

Then, obviously, you did very well.

 

I've never put a maintainer on the aux battery, just the main battery.

My aux battery is original and now 9 years old. Your post got me curious, so I checked the voltage on the aux battery (car hasn't been driven in several months) a couple of days ago and it was 12.5V (maintainer disconnected-ignition off)

I then disconnected the aux battery and put a light bulb load on it until it dropped to 11.5V. Reconnected the aux battery and the maintainer on the main battery. Checked it a day later and it was back up to 12.5V

Strange, but it does appear that when charging the main battery, the aux battery is charged as well.

 

Just got a quote from my MB dealer here in Birmingham, AL to replace both front and rear batteries: $764 plus 9% tax = $832.76. They did not breakdown the cost of each.

Quote today to replace brakes: "FRONT BRAKE PADS AND ROTORS RUNS AROUND $700. REAR BRAKE PADS AND ROTORS RUNS ABOUT $650". With 9% tax added to this = "around" $1,471.50

I have 43,000 miles on my 6 year old E350. I will wait until I get some warning lights before proceeding. I am not a DIY guy on car repairs.

 

Keneaise, try Interstate Battery, bought mine in Mobile but there must be a dealer in Birmingham, also Autozone has a good replacement and they install also.

 

It is expensive keeping gold plated tools shiny.

(I am in the wrong business)

 

I have a set of Wagner pads and sensors for your car I'll let you have for $25+ shipping. I drove my rotors 130,000 miles before replacing and my guess is yours F/R are still good. You could do your front brakes with the $25 pads from me and be out about $35.00 total vs $700 and new rear pads are about $60. IF you can change a tire you could do front pads. Punch out two pins compress the piston pull old insert new. easy peasy.

New battery Bosch from PebBoys about $130 and new aux battery from AZ is about $60. You could get all the work done brakes and batteries about $250 IF you do some of it yourself. If not they just pay the Mercedes Tax to the dealer.

 

Just bought a replacement Group 49 battery from local M-B dealer. New E350 battery p/n 000-982-33-08 was $193.05 without tax or labor. For comparison O'Reilly wanted $169.99 for a similar battery.

 

Just in case anyone find this useful, it is indeed cheaper to have roadside assistance replace your battery They don't charge you any labor while the Mercedes dealer does.

My battery is low and it is cheaper for road side assistance to come to my house and change the battery than to go to the Mercedes dealer... They are on their way and the AGM main battery is only about $240 when purchased through road side assistance.
