I\'m using one for my 5600 and it works just fine. You do have to make a slight modification though. You\'ve got to make a smallish hole in the case material for the tab on the BL08 battery to fit into it. Not hard to do, particularly if you take the charger apart first. I\'ve also heard that you can saw the tab off the battery to make it fit, but that seems a bit risky to me. I used a dremel tool to add the hole to the charger, took about 15 minutes to take it apart, make the hole, and put it back together again.
