For those who want to restore a Macintosh Plus and are looking for a solution to replace the internal 4.5V battery with one that's practically impossible to find these days, I got a battery pack on AliExpress that holds three 1.5V LR44 batteries, so it has a 4.5V output. Given their small size, I was able to use two packs in parallel to increase capacity. The size is perfect. A little self-adhesive foam fills the gaps nicely and ensures a snug fit.

In short, there are probably other solutions; mine cost less than $10.
