Memory Saver
I have a 2005 C200, and I read that when the car runs out of battery it's really a problem. Some people recommend a Memory saver that can be connected to the car for 30 to 45 minutes to keep the car from running out of battery while the new battery is installed.
My question is: Is this a must have? If the answer is YES, what are the best brands/models in the market?
Thank you for the help.
