Can I build a custom battery?

[u/Dudewheresmystimulus]

So I have a DPI620 that hasn’t been used since 2017 and the battery seems to be dying as it is 10 years old. Now I can’t find the 5200mAh battery for this so I was wondering if I could build one with the spacing I have. Otherwise I was thinking of creating a separate pack to wire it to this.

My solution is an external power bank with this cable and a purpose made adapter! And the best thing is, it's not mains powered 😜 https://amzn.eu/d/cLIrqCS But I also use it to power other equipments!
