Block Heater - Odd Question about Plugging In
I have a 1984 300D with a block heater. Last winter, I lived in the Ottawa area where temps were often down around -35C. Plugging in for a few hours before I needed to go anywhere seemed to do the trick & I didn't have any problems starting the vehicle.
This winter, I'm living in a different part of Canada, and just bought a new battery. The mechanic advised me to keep the vehicle plugged in "all the time" (as in, all night, every night), to protect the battery.
I wasn't aware that it was necessary to be plugged in "all the time" - i.e. overnight to protect the battery. Is this valid advice?
I'm asking, because I'm going to Europe for 2 weeks soon, and my vehicle will be parked outdoors in cold temps (potentially anywhere from -10C to -40C). Obviously, I don't want to plug it in for this entire time while I'm gone unless this is necessary for some reason.
Any advice about this would be much appreciated.
