You want Optima 34 red top or Optima 35 yellow top?
Optima D31M is a Marine and Truck (as in big truck not SUV) battery.

I live in Canada and getting an OPTIMA battery is difficult where I live. I called the Canadian Distributor - East Tenn/Power Battery 1-800-668-9303 - and they quoted me the following prices:

$350.00 Canadian for the D31T Yellow Top
$280.00 Canadian for the 34/78 Red Top

My alternative is COSTCO. Here is what they have and prices:

or

Have you considered the factory route -- around $150 CAD perhaps? Have seen good feedback here for MB & Interstate.

Warranty on the factory battery is not great and I may be putting the car away for 4 months in storage during winter.

Whixh model OPTIMA do you have? Is it the Model - 75/35? Which Mercedes do have it in?

Not sure what the problem is - I think any of the 34 or 3R redtops will fit.

It's not the same size group as what is called out for a CE- but there is lot's of room. I purchased one this week. I think mine was a 34/70Y or something...

Just go measure your battery tray and the max height... easier than asking.

If you are going to store the car for 4 months then put a trickle charger on it and/or remove the battery as has been previously suggested. Complete discharge = death to any lead acid battery. Even deep cycle batteries are only resistant to this up to a point. This is the most important thing to know about lead acid batteries. Keep them charged up and they will last a long time. If you let it go to zero then it is a goner.

Thank you for the advice. I intend to buy a Battery Minder or Battery Tender.

Try www.batteryweb.com 1-877-746-2288(8 am - 5 pm Mon-Fri EST), thats where I got mine from. Optima batteries can be shipped because they don't leak or spill.

The Interstate battery is about $160-$170 Canuck-bucks, and is an awesome battery. No fit problems like the Optima and great warranty. It's essentially the OE battery with a much bettery warranty, but no fancy "Star" on it.
