2013 CLS550
2013 cls550 wont start - video included

Car's been having trouble starting lately, sometimes taking a little while to turn over.... struggling to start.... also weird stuff like not being able to roll the windows down right away after starting car - just came back from a four day trip and now it won't start at all - see attached video. Not a car guy so if it's something simple like a battery feel free to call me dumb. I replaced the aux battery on this a few years back, not sure if the main battery has been changed since I took ownership in 2017. Thanks in advance.

My guess is main battery.

Take the main battery to an auto store that tests batteries, they can tell you if its good or bad. They usually don't charge (pun not intended) to perform the test for you.
