Help with old camera battery (lemmy.ml)

Hello,

I have an old sony camera that has an old Ni-Cd battery (6V 3000mAh) and of course now the charge doesn't last long. They do sell "new" batteries for it but its from Aliexpress and I don't want to rely on 1 not so reputable seller incase I need a new one. So I wanted to repair it and "upgrade" it myself, but im no electrician or anything I just like to tinker with electronics so I had a few questions.

The battery and camera only have 2 connections, positive (+) and negative (-). I saw on aliexpress that they sell a 6V 4200mAh battery pack, which is made of 5xAA (1.2V) Ni-Mh rechargable batteries. Would it be as simple as that, if I connect the positive and negative to the corresponding ones on the old camera it should work?

Is there anything else I should take into consideration?

EDIT: The camera Is a Sony CCD-TR403 EDIT2: or would it be better to build my own battery pack with 18650
