Default New C5 Owner (2003) Fault Code Question

Just brought home a 2003 C5 that was owned by an elderly couple and hadn’t been driven much the past few years. I ran diagnostics and got the codes below. I’m going to try and reset the TPMS ones tomorrow. The battery was replaced about a year and a half ago and the widow told me her husband used to pull the battery out every winter. So I doubt anyone ran the diagnostics after it was replaced. My question is could these codes be due to the new battery and/or removing it each winter or should I really look to investigate these. I hate to do a bunch of work if it’s possibly the battery. Car seems to be running fine. Thanks!

I believe most of those codes are related to battery disconnects.
Clear them all and see what comes back now that you have them written down.
