Are you sure you needed one? My charger was not making contact with my remote very well and it was not charging well, and my battery wasn't lasting more than a day. Every day of use, it would be almost dead. So I put solder on the tabs on the remote base and it is not making better contact and now after a full day it's still at 3 bars of battery.
