To correct this problem will require replacement of the battery. It is fairly common as these get older. If you need to find a replacement battery, let me know and I will be happy to help.
Yes. If the battery has failed, it will still cause it to lose power.
I wouldn't buy locally because it will be 3-5x what you will pay online. I will find one online for you that you can have in one day for half the price or less, including shipping.
Ok... Just put my foot in my mouth, not realizing this was (literally, at 26 years old) an "antique". It will take me a little while longer to find it than I thought but I will get back to you shortly.
Does your battery pack happen to have a part number on it?
