Creative ZEN TOUCH 2?

Does anyone know if, and how can I replace the battery and the hard-drive (maybe switch to flash memory?) on a zen touch 2? Every time I try searching for it, it always gives me results fro different zen models… It’s not listed even here, That’s why I had to chose a different model (can the admins add it to the device list? thank you).

It’s this one right here: https://www.cnet.com/reviews/creative-ze...

Surprisingly the battery still holds for 12-16 hours and the drive loads fine, but after almost 20 years, you never know when something will fail.
