I still have trouble with batteries in remotes. I never seem to have the correct size when I need them. This one takes “AAA” batteries? We have 30 “AA”, 16 “9-volt”, 6 “C” and 12 “LR44″. What I wish for is wireless power that will send electricity through the air from the television to the remote. Or maybe all televisions will have built-in cameras to allow you to operate all the basic controls with gestures.
