Do I need a 55++ battery to use a 27++ battery?

I just recently received a 9 cell 27++ battery for my T510. I've never seen this kind before - it attaches to the bottom of the laptop. If I try to use it instead of a 55++ battery, the laptop receives no power. 

Do I have to have both batteries in place for it to work? (I don't have both, so I wasn't able to try this myself.)

Yes, you do. The 27++ is just a "slice" battery.

No, the laptop is perfectly happy running with just the slice.  Looks funny, though.  And I wouldn't drop it.
