What do I do when the battery is not held tightly enough in the mouse?

What do I do when the battery is not held tightly enough in the mouse? This is the second of these mice I've had and it is already, after only 2-3, months showing the same problems I had with the first. The spiral portion of the battery holder is compressed and does not hold the battery snug, leaving me with no curser response. I have tried pulling it out more but it seems to have a 'memory' action and is just compressed again when the battery is reintroduced.
