Then you're on the right track. Once you see it done, you'll be able to do it yourself with confidence. Good call.

10% off at AutoBarn

I was about to pull the trigger on ordering a new Dekka EAS9AGM49 battery for my 2006 E320 CDI yesterday from Autobarn at a cost of $195 delivered (ouch). Decided to sleep on it and glad I did. This morning, I went to their web site and found they were running a 10% off coupon promotion. Jumped on it and ordered the battery for $176 delivered. Still not cheap, but easier to swallow than $195.

I gather Autobarn does these coupon deals off and on.

I took my car into service and they said I had about 530 amps when they tested the battery (I don't know if that is the main or both). I don't know if that is bad or still ok. What is an approx. minimum before it will start? They just said it would be a good idea to replace them before the winter time. They wanted $440 to replace both, which seems reasonable considering the parts are about $275. I just want to do it myself though. It was not a MB dealer, but a well-known, trusted independent that specializes in MB. Any help is appreciated.
