My mid-2009 13" unibody MacBook Pro died years ago. It's probably not worth fixing. I am just curious if a dead CMOS/PRAM battery could have caused its demise?
iFixIt doesn't list any non-primary batteries in its online store or replacement guides for any unibody Macbook Pros.
Did these models lack one altogether or was it just soldered to the logic board (In which case it'd be kind of like planned obsolescence) ?

Why does mid-2009 MacBook Pro lose date and time
I've not seen any mention of a separate internal backup battery for MBPs either.
I've been inside my Mid 2012 13" non-Retina MBP that has the same form factor (A1278) and logic board architecture as yours and I've seen no user-accessible extra battery.
Did unibody Macbook Pros have a backup battery (CMOS / PRAM)?
