Storing SL350/keeping batteries charged
Is it a good idea to connect CTEK chargers to both starter AND convenience batteries if the car has to be stored for a couple of months?
Would this do any damage to system electronics?
Any advice would be appreciated

The CTEK charger is an excellent way to keep your battery charged while your car is in storage. You only need to connect it to the battery in the trunk and it will keep both batteries charged up. Do not use 2 chargers. TwinCam

I've used a single CTEK in the trunk for 4 years and can confirm it does the trick.

CTEK Multi 3300 charger (what position do I select)...
Wow, this is great news. I already have a CTEK Multi 3300 I use on my Corvette.
What setting would you recommend it be placed on when charging through the trunk battery? Should I select the third position (norman passenger car setting) over that has a picture of a car or go to the fourth setting that has a picture that looks like an asterick or snowflake?
Thanks!
