The Macintosh LC II was released in 1991, as a low-cost color Macintosh. It succeded the Macintosh LC, and was replaced by the Macintosh LC III, all of which followed the "Pizza Box" case design.
Recap the Power Supply!
I am sure that it will have a TDK power supply in there.
Replace just the capacitors on the secondary side (you will see they would be bad as they start to leak). Be sure to clean the PCB before you put the new capacitors in. You will also notice that some of the values of the capacitors used there are obsolete, and you would want to use nearest higher values.
After you are done with the Power Supply, you will probably want to recap the logic board as it is also long due. Old capacitors there will cause lots of problems, from not booting, to whining from the speaker, to white screens at boot, random lockups and more. This is a bit more involved, but manageable.
The PRAM battery should be removed and will not cause any problems if it is removed. The only model I remember that acted funny without PRAM battery was the LC 475 series, others did not care about it.
