How do you replace the electronics Battery 2004 SL600 (R230)?
 

I have a 2004 SL600 (R230) and both my starter and electronics battery are dead because of age, the cold weather, and I let it sit too long. I took the starter out with ease. I had NTB check it and they said it was dead and could not be recharged (I had tried before hand to charge it for an hour with a car jump and also a plug in battery charger). I bought a new one for MB parts dept and have not put it in yet because I want to get a new electronics battery. It was going long before the starter.

Anybody know how to take out the Electronics Battery? It's well bolted down and I removed every bolt that I could see and the retaining clip, but it will not budge. Any tips on taking it out?

Also, I bought an MB battery for the starter because I could not find the equilvalent at autoparts stores. Are the generics okay for the electronics battery as long as the size and CCA are the same?

Thanks in advance

Mercedes roadside assistance does batteries any where at over the counter price with no labor!

Yeah, but I was hoping to not buy an MB battery for that. The battery at the autoparts stores are like $100 where as the cheapest I could find the MB electronics battery was $203 + tax at a local MB dealer (most expensive up to $320 at another dealer).

I still may go the roadside assistence root if I can't get the battery out....still looking for tips on taking out battery. Anyone?

Thanks


BTW for people that want the MB batteries and live in the DC area. Here are the 2 cheapest:

MB of Tyson's Corner (VA): $155 + tax for the Starter Battery and $203 + tax for The Consumer Electronics Battery

Herb Gordon MB (MD): $173 + tax for the Starter and $220 for the Electronics. The said they would price match Tyson's though.

The dealers charge whatever the market will bear!
I have heard horrors from other posts even as far as charging labor for roadside!
