It sounds like the li-ion battery has swollen, you may need to take the remote apart to get it out.  Cant think of any other reason for it sticking?

Dont forget, it does have a two year warrenty, how long ago did you buy it?  

I had the same problem and the battery wouldn't stay charged for more than day. I used a biro pen top to lift the swollen battery up and out. Logitech replaced the battery within 3 days under the 2 year warranty.

thank you both,the battery had swelled up quite a lot,about 20 to 25 % at the thickest point.

levered it up a notch with small screwdriver and used point of very sharp knife to slide it out

should be ok for another 2 years
