Another Lisa 2/5 question

Hi all, Well this weekend I got the boards out and removed the battery pack. I ended up using White Vinegar to clean up the mess the batteries had made. Seems to have worked OK. Now I've got a problem. How do I go about replacing the four batteries in the pack? I've no idea what they were rated at. Do I need replace them? I noticed an On/Off switch next to them, any ideas what it's for? Zane | Zane H.
