The item has a two day battery life off a full charge.

Very long battery life. I charged it Saturday night to 100%. I used it all day Sunday including a 2 hour run, and now here I am on Monday morning and the batter is still at 73%. You can easily get a week out of the battery with the GPS on the entire time.
