Mac Plus spec battery?

I would try and throw some old Mac advantages. Some had removed batteries. I would try to get my hands on a couple of good batteries, but I'm not sure of the specification other than alkaline batteries, 4.5V. Can someone help me? The size, the diameter and the length will be useful I think. I don't know what is the technical term, maybe form factor.

Yes, it's a special (approx. 17 x 50 mm) alkaline battery of 4.5 V. try a search on the web for 523 or PX21 (or equivalent).

It is possible to start a Macintosh Plus without battery in place (but the battery would retain the date and time settings).
