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

Legoing together 6 volts worth of battery to the camera and getting it to operate is pretty easy and straightforward. 5 x nimh is ~6v.

The problem is properly charging that pack once you make it. The nicad charger that came with your camera doesn't have enough umph to properly juice up the nimh

Lithium ion would be a pretty sweet pack to make. You could charge it very quickly. But it needs to be balance charged with a purpose-built lithium ion charger, and you're going to need to do some kind of voltage regulation because a two cell pack is going to be way more than 6 volts.
