No, it does not. The change you see is purely temperature related. The circuit will start showing a depletion of the battery if the 3.00v battery reports 2.99v! New batteries are above 3.00 by just a bit, so they don't trigger the circuit when temperature fluctuations affect them. Removing and replacing the battery you probably held it long enough to warm it up, or the battery recovered the .01 v by being removed from the circuit.
