Apparently after time, the battery cover widen the gap with the battery itself and thus resulting in a split second disconnection between the battery and the terminals when you lifted your mouse and you lose the connection.
How to fix it?
Remember using a piece of unwanted paper folding it and slip it under a 3-legged unbalance table? Well, that's exactly how you do it. Simply open up the mouse cover and put a folded paper and cover it back to eliminate the undesired gap.
Voila, you had your mouse back in no time!
