My sister-in-law has a 2007 230 SLK and will be putting into winter storage. She has asked me what needs to be done. I have a Miata and always disconnect the negative battery cable. Is this a good idea on a MB ? We are talking a Canadian winter which is hard on battery life.

Thanks in advance for your info.

P.S. My name is not Al.

 

An SLK is not a Miata. Agree with Forced--do not disconnect battery.

 

I have convinced her to talk to MB dealer. Thanks for your info. Case closed.

 

The SLK 230 was made from 96 - 2004

 

Isn't it 2005?
