Sorry to hear that. Mine bit the big one in early November. It took 11 days in total to get the new battery in, but it's been fine ever since. Our dealer was very helpful, too. Ours was the first they had the pleasure to replace, but they seemed to do a good job.

From what I gather (although I have no definite proof of this), the replacement batteries have been redesigned. It doesn't affect the operation of the GL.
