I'm trying to model a hot fluid running through a pipe that goes next to a cold cilindrical battery and I can't get the thermal model to read the battery as a solid body. Please help, it's for my Master's dissertation due in 10 days

Do you need to model the battery as a battery or just as a hot solid? 

[David Nadal]

The battery is a solid

I can get the model to show a temperature contour, but the temperature reading range on the colour map only shows 300K, which is the fluid's inlet temperature, while the battery and its pipe are 273

OK. I assume you've used share topology to get a conformal mesh. Turn the battery cell zone to a solid. You may see some warning about internal/interior/walls: resolve those. Add an energy source to the battery and solve. 

There should be (or was) an electronics cooling example/tutorial in the Help system. It's similar to what you're doing, in that a solid is getting warm and the air is then taking heat away from it.
