The term of the Squeezebox with this battery is super. At normal listening levels, five hours of runtime casual inside (after five hours of operation, according to display 20% remaining charge). The Squeezebox is running at the moment during the day with battery. Overnight the battery is charged again. What is the battery life will be revealed in time. My impression is positive, so I'm gonna buy this battery for another Squeezebox. _ Addendum: The impression the second purchased battery is also positive. The purchase was worth it _ Addendum July 2013: So far show both purchased batteries no restrictions. Operation of the Squeezebox is still more than 5 hours possible.
