MP 1,1-5,1 It wasn’t keeping time, so I was going to replace the battery, but….

Then I noticed this plastic piece in between the battery and the contact on the battery holder.

My guess is that it was inserted by factory that makes the logic boards and was supposed to be removed during final assembly of the machine, but this one got missed and has been there for 15+ years.

I measured the battery and it was reading 3.4volts still, so I put it back in, sans plastic piece, and it’s working fine now.

Yikes! I'd check back in there from time to time to make sure it's not leaking since it's so old.

might wanna take it out to inspect it, but be very gentle. that clip is super fragile.

I would like to inspect a firmware dump of that machine. Could see, if it is a refurbished one, or if it is not serialized completely.
