The sealed battery in your link is an AGM type and they are generally excellent and about the only way to go if the battery must be in an unvented compartment. However, the U2200 is much less expensive and a quality battery if you have a vented area for it. The U2200 is a 6V, so you need to install them in pairs. A pair of U2200's will have about 30% more capacity than two of the AGM 12v's you referenced.
