Battery problems again

Hi, I upgraded in December 2025 to an Everstart Platinum AGM battery. I had previous problem with Mazda battery and thought I did a good thing. So, last week I opened passenger door to load the car. Panel was flashing. Went to driver side. Nothing it was dead. Triple A, he mentioned 3v on his read. He tried something different, car started. Agreed to run up the road to Les Schwab so they can charge for several hours. Tech finally came out said cannot get past 850. I’m an old lady no idea what this meant but apparently not good news. I do have a 4 year replacement warranty. Here are some numbers of my battery H5/LN2/47 12 volt. Do I need a better battery for my Mazda? Anybody else have similar experience? I appreciate any thoughts.
Thank you,
