Glad I got this when I did.

If you have a Harmony 1 you better examine the battery. Mine was about 4 years old and started not holding a charge. I had to pry out the old battery which was swollen so much I think it would have eventually exploded. I never saw anything like this before on a rechargable battery. If yours is getting up in years consider replacing it.
