I recently replaced my early 2008 24" iMac PRAM (CMOS) battery and would like to know if my 13" MacBook Late 2008 (Aluminum) has one of those or the main power battery supplies the PRAM (CMOS) functions like in my 24" iMac.
Thanks a lot in advance,

Hi there. Yes it does, but it is on the back side of the logic board and the entire Macbook has to be taken apart to change it. Not likely to be a problem as the Macbook comes with a replaceable battery.I have not heard of anyone having to replace one. And I am not sure the aluminum Macbook has one . From 2009 0n none do.
The thing is some people say it has one and other people say it's got a sort of a component that keeps a little of the main battery energy in order to mantain basic settings, clock, etc.
iFixIt's teardown of your model seems to illustrate that it does not have a seperate PRAM battery https://www.ifixit.com/Teardown/MacBook+Unibody+Model+A1278+Teardown/589
Thanks for your input Mike. Just what I needed to discover: the back part of the mother board does not show any replaceable PRAM battery whatsoever. So running my laptop with its own battery is enough then.
Thanks a lot,
