I did a similar swap for the sending unit of my Sun Tach.
Took some crap for it (on this forum, I think) but it seems to be working fine (it's been thirty years, I think).

Well, I noticed that they were physically about the same size as a modern "AA" size battery, although the modern battery is 1.5V and these vintage batteries were 1.35V.
I asked one of the electrical engineers at work about it and he said "...I'd just put a couple AAs in a flashlight and run 'em down until they're 1.35V".
That's what I did and it's been working fine ever since.
