    Sorry, "the spare lid that came with the TS" on my previous reply should have read "the screen surround that came with the TS."
    Meant to edit it at the time but got distracted by something (I forget what) and forgot the edit.
    Now I just have to remember what I was planning before the forgotten edit occurred to me and I'll be completely up to date.
    Hello 2019, Happy New Year everybody!

    Huh say what?!

    Can anyone else verify this? And more importantly, if so, can this be added back in easily enough? Loosing this actually is a MAJOR strike against the ATI version.

    As geeky as it sounds I kinda wanted the 2.8 ATI version to match my 2.8 VR6 engine conversion... But, I think I want a second battery more. $4!+ ...

    Oh well if that is what it is with no fix for it, then the other ones are a good bit cheaper and easier to find.

    Could of changed in new version of the cf-31 but here is what I found about it.

    Scroll to the last post in the link before for explanation.

    No you can not retrofit the 2nd battery option to a CF 31.
    Different motherboard and no room for the connectors.
    If it was not optional from the factory, you can't add that option.
    No you can not use the 2nd battery with dedicated ATI graphics CF31.

    Thank you Jester321! That explains most of it.

    Okay Shawn, so not in the MK1, or any with discreet graphics. Gottchas. Now do I need to run the model number through configurator and figure out if other MK2-4 models had it optional? Or do basically any other than the MK1 and those with the ATI discrete graphics have the option?

    So next I guess is to decide how much I really want the extended life... What is the average runtime for a CF-31 on battery, VS one with dual?

    And honestly, is there going to be a big difference in performance between a 2.5ghz, jumping up to the 2.8 with ATI? All other things being even. SSD drive and maxed memory. Unlikely I would go with the 2.5 when other slightly faster options are available for not too much more... But whatever.

    That's my understanding of it.
    ----------------------------
    Performance difference.
    I would imagine it depends upon what software you are using.
    Also, from what I understand the Windows 32bit-3.2gb memory limit includes video ram. So if you have the ATI model, you would be better off running a 64 bit version of Windows and 8gb of ram.
    -----------------------------------
    Like Toughasnails said, the 2nd battery gives about 1.5hours more. It does make the main battery "hot swappable" so that is nice.
