I don't think you'll find one that fits. I've tried.

Seems no one has found a starter battery for the R230. Out of curiosity I plugged in a 2004 SL500 into Interstate batteries application locator on their website. They state the following battery fits the R230:

Interstate Part Number: MT5 AGM

Height: 7.50 Inches
Length: 11.00 Inches
Width: 6.94 Inches

They do not state if this is a replacement for the Starter battery or, the Accessory battery. IIRC the starter battery is fairly small compared to a conventional battery so, this may be worth looking into.

For about $125 bucks better to keep it oem. The electrical system is too sensitive to be screwing around with!

Both batteries went bad in my 2008 SL550 recently. My local shop could not find an aftermarket battery for the front battery and replaced it with an OEM battery ordered in from a MB dealer. He replaced the rear battery with the Interstate AGM battery they recommended. It failed within weeks (would not pass the load test at the MB dealership). The MB service rep said the Interstate battery had much lower capacity than recommended by MB and replaced it with an OEM battery. So far, no more problems although it has only been a couple of weeks. If you can get batteries for $125 your dealer is much friendlier than mine. Mine were MUCH more than that! Vic

1-800-FOR-MERCEDES

Has anyone called 1-800-FOR-MERCEDES?
They supposedly come to your house, no delivery fee, installation fee, nothing other than the price of the battery . I do not know their pricing for battery.

I called MB roadside,they were at my car in 15-20 minutes. Replaced the starter battery and checked the trunk battery and charging system. 215.00. I was impressed with the service.

What is the number for roadside?

I have a dead front battery and I am stuck 1000 miles from home. I called the nearest dealer, which is 70 miles from me, and they don't even have a battery. They also want 225 dollars for just the battery. Please post the phone # for the roadside assistance. Thanks

Been there done that. You're outside the nearest dealer's response zone. All roadside assistance will do is send out a third party responder who will flatbed your car to the dealer. Good luck.

Starter battery just died in my 2003 SL500, so I did a quick search and found this recent thread. I'm posting to confirm that the best way to replace this unusual hard-to-find battery seems to be MB Roadside Assistance (if it's available in your area).

I called and they were at my house in 10 minutes with a new OEM battery. He tested both my batteries and only the starter battery was bad (its about 5 years old). No labor charge and the price (with 2-year warranty) was $209 including Florida tax.

I currently have 2 MBs and had 2 before these, but this is the first time I've used Roadside Assistance.

There's no end to complaints about the high cost of MB dealer service, but I highly commend MB for their terrific and very reasonable Roadside Assistance.

LOL So true! Mercedes doesn't Manufacture Batteries!

But I have a Interstate AGM in Rear and couldn't be happier. The front starter Battery is not AGM as its only purpose is for Starting, the rear takes the beating with the current draw.

I went duel lithium batteries in the trunk and saved about 80lb, not very cost effective but a great performance mod.

It was Voltphreaks, I don't have the part numbers to hand, call them and tell them the guy with the sl600 in England sent you and they should be able to help.

If that doesn't work pm me and I will look it up.

My shop just remove the original battery mount and fit in an universal aftermarket one for less than 100 bucks.....of course you have to put some absorber such as cardboard paper or plastic bubbles around the battery to well secure the battery in place

Mercedes Misbehaving: misfires, difficult starting, warning lights

Quick line of thanks to you all: car was (badly) misbehaving resulting in the dashboard looking like a manic Christmas tree with all the lights.

First off, the engine started to misfire horribly. Check engine alit -- the whole car shuddering. Stopped and parked it and when re-started she was fine! However, the car was hot and the engine wouldn't hardly turn over when starting. Still, she was running and no lights on the dashboard. Then it happened a couple of days later.

This time she wouldn't start and the electronic door opening failed. Key in the dashboard got her lit up but with lights flashing, clock hosed, warnings about missing third stop light, battery/alternator failures (hint: this was the key). These machines are expensive to repair and I was getting seriously concerned. Then -- THIS blog. I found out several things from you lot!
  • Batteries are not meant to last but maybe 3 -- 4 years in Florida heat. Mine was nine years old.
  • That a battery can be fine one day and die the following. The deterioration is very rapid when it happens.
  • The front battery is simply for starting the car.
  • The rear for all the "consumables" (i.e. the entire rest of the electronic system that can and will induce misfiring). This may also induce erratic behaviour when it starts to go south.
  • It is (very) unwise to use a non-OEM battery. They have different resistances and the electronics will pick that up and misbehave (or, possibly worse in that the systems maybe damaged by an aftermarket battery. Pep-Boys are NOT Mercedes engineers or mechanics).
  • There is a number to call for ANY MB owner - -whether or not the car is in warranty.
  • That a battery replacement from the roving Merc technician for Roadside service is CHEAPER than at the MB store.
  • Despite all the electronic systems going askew, the only thing that didn't sort itself out was the dashboard clock. And I've never been able to successfully sync that with the head unit anyway. PITA

I paid $210.34 inclusive for a new battery for the 2007 SL550, installed, tax and old cell recycling.

Boom! *drops mike*

Thanks again to everyone that contributed to this and my ultimate successful day!

Cheers.

This is the same battery the prior owner put in my SL550 only a few months before I bought it. Almost 9 months now and no issues. I can't speak what the MB OEM battery looks like under the hood, but this one looks like it belongs.
