Narrative:
Stores brought a battery pack to maintenance office (which wasn't ordered by me) for aircraft X. Crew chief asked me to deliver it to the mechanic working on aircraft X. So I did. I then helped that mechanic by cleaning up his work area while he changed out battery pack. I saw that the emergency lights tested good after he was finished. We closed up the plane and went back to maintenance office. While the other mechanic was signing paperwork, I thought I could help by filling out his abcd tag for the part he removed. I didn't notice I filled out a tag for a different part than we installed. I never saw the installed battery pack, because it was packaged when I delivered it, but I assumed they were the same cpn's, because I had seen that the emergency lights tested good.
