The battery you indicated appears not to be an AGM. Flooded batteries in general are much cheaper than the AGM. My battery compartment is not easily accessible, so having to maintain the water level in the battery, worries about operating it while healed plus the potential danger of spills makes me much happier to spend the extra $$$ for AGM batteries. One less thing to worry about. Dave
