If I were to perform an experiment where I dropped a battery from a certain height and recorded how fast it went down, would the results change with I added more weight?

NO. All objects, when free-falling, fall at a constant acceleration of 9.80 m/s². The formula to calculate the force of gravity on an object is Fg = m*g, where m is the mass of an object and g is the acceleratin due to gravity. As you can see from this formula, since g must stay constant, if the mass increases, the force due to gravity must also increase. Therefore, no matter what the mass of an object is, it will still accelerate towards the ground at the same rate.

Depends. In a perfect world, no. But you must consider air resistance (drag).
Same physical size and made up of the same material on the outside, no prob.
Plus, the motion of the falling object causes changes (Vx) so if you just tape a weight to the battery you cause a different spin with diff drag and motion vectors.
Now the height matters a great deal -> 9.8m/s^2 so if you test at a low height - the change will be minute, but if you use a 3 story bldg, well, the effective change will be additive. Also, quite painful if you are testing above a public sidewalk.

No. The driving force increases in exact proportion to the mass, so the acceleration is constant.

Yes, you would record a faster time.
