2016 CX9 at 35,000 miles;
Purchased "new" and full warranty as mgr demo at 4800 miles. Battery still OEM but not sure how it tests. I will have dealer LOF and checkpoints this week and can update. I've been known to tender the battery of my two cars with a cheapy Harbor Freight motorcycle battery maintainer. Once or twice a year though.![Face with rolling eyes :rolling_eyes: 🙄](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f644.png)
