What type of battery goes in this?

There's no battery for this. No moving parts and no electronics.

Do refractor telescopes need collimating ?

No refractors do not need collimation

Will this work on a Bushnell North Star? I believe it is a 3.5 maksutov type.

No it will not work as your scope is a Mak-Cass type of scope... You have a cover plate on the front glass aperture, your collimation is corrected using the screws located under the corrector plate. You have to do a slightly off focus star adjustment, the star should look like a concentric set of rings within each other when collimated properly.http://uncle-rods.blogspot.com/2009/07/zen-and-art-of-telescope-collimation.html

Will this work on Celestron PowerSeeker 114EQ?

Hi! The Collimation Eyepiece will work for your telescope. Your telescope takes 1.25 inch eyepieces which the collimation Eyepiece is made for.
