Battery Replacement - DIY or Dealer?

I am interested in installing an AGM battery in a 2020 RX350. AGM batteries require a slightly higher charging voltage than what is delivered by the stock RX350 alternator (they do "work" with the lower charging voltage, but it is definitely not optimal in terms of the life of the battery and its operation).
One possible workaround for keeping the AGM battery in good shape would be to charge it overnight once a week with a smart charger that has the AGM setting. Combine this with a battery test once every six months to confirm all is well. Here is a decent charger on Amazon: https://www.amazon.com/NOCO-GENIUS5-...1&gad_source=1

When the battery died in our RX I found the key difficult to unlock the door. I gently used a pair of pliers and a soft rag to twist the key. Lube is a great idea! Dang I shoulda thought of that!
I replaced the battery with an Interstate AGM from Costco for about $160 as I recall.
