I drive mine throughout the winter, but I don't drive a lot as a whole. I usually drive it 1-2 times a week, usually on back to back days so I sits outside under a carport for 5 days in a row without starting, sometimes more.
I have a battery almost 2 years old. Nothing special, just an autocraft I think. I have a small ritual when I start the car. I turn the ignition to run and let it sit there for about 30 seconds or so, until the dinging is done anyway. Make sure the HVAC is off and then crank. Takes maybe a second longer than if it is summer.
It is my experience that this car is really not a fan of cold temptures. It will artfically hold the RPM's at the 1200 mark for a good 45 seconds before coming down to regular idle, it also makes some uneerving noises after a cold start. Sometimes it whines a bit, other times it doesn't. Either way, my serpentine belt is less than 6 months old, replaced it at the beginning of winter for this reason alone. I let it sit running, for maybe 10-15 minutes and its back to normal, after it reaches full tempture its completely fine.
My biggest problem really is flatspots on my tires. Even if I don't have to go somewhere on my days off I try to go out and just drive the thing weather permitting because I want to warm up the tires. I have Hankook Noble 1 Ventus 2's (terrible name) and they perform rather well I think, but they do not like the cold what so ever and it takes a good 20-25 minutes of constanting driving to get them plyable again.
Oh yeah, I had the door handle stick once. That sucks too.
I'd also like to add that sideways snow hooning is very easy and fun in the LS.
