The Hyundai Tucson, model year 2017, uses a group size 48 battery, typically with 760 cold crank amps, which can be purchased for $150 from Your local brick and mortar car part stores. Not sure if You need a new battery Here are some signs that maybe it's that time: You notice that there's low fluid levels in Your battery, and it's a sealed one, where You can't add to it. It takes longer than usual for Your engine to turn over when You're trying to start it. Your check engine light (CEL) comes on, with seemingly random diagnostic trouble codes (DTC). You observe leaking acid or heavy corrosion on the terminals.

The battery in my 2017 Tucson SE is definitely NOT AGM. When removing from car I can hear the electrolyte sloshing around. AGM doesn't do this.
