Quick question for PB 150 owners

[3lectr1cPPC]

I want to pick up a 150 at some point but I have a question about the PRAM battery. According to a page on oldcrap.org, these use the leaky Varta NiMH PRAM batteries that many laptops of the time used. However, despite this being something I’d expect to be brought up a lot, oldcrap.org is the only place where I’ve seen it even mentioned. Do these all have them, or was their’s just an exception? If so, then buying untested for cheap would be a real gamble.

edit: found this old thread https://68kmla.org/bb/index.php?threads/powerbook-150-pram-battery.12446/
And a YouTube video that also confirm it.
