Consumer Battery Failure

RE: Consumer Battery Failure
When my 2004 SL is not driven for 2 weeks either of two things may happen. I will come out to the garage and find that the car has mysteriously locked itself. Dealer claims that is a defense against the battery running down. (Explanation sounds suspicious to me!). Beyond that, I have driven the car when the battery was almost dead. Never has been totally dead yet. (That may take 3 weeks.).

Has anyone had problems with the Consumer Battery going dead if the car is not driven for two weeks?

RE: Consumer Battery Failure
you need to purchase a maintenance battery charger. Mercedes sell one that won't fry the electronics in your car if left on over a period of time. It sells for around $135.00. I was able to find the exact same charger without the Mercedes symbol for $70. It is manufactured in Sweden by CTEK and it is model 3300. You can order one from www.mustangsunlimited.com or many other online sites. This is a "must have" for cars that are not daily drivers. I don't know if other "trickle"chargers are safe for the car's electronics. This one is approved by Mercedes-Benz. I hard-wired this chargers leads right to the battery terminals so it's a simple "plug and play".
