i recently acquired an awesome 128k 1984 macintosh in great condition with keyboard + mouse

The unit does not power up however, and i was wondering if this could be the result of the battery in the back being totally corroded as well as the contacts.

I have found a local place where can i order a replacement battery for $20 - should i go for it or will the problem probably be something else?

thanks MLA -!! :?:
