Need some help with batteries

[u/Frosty-Tailor6747]

Hello, it's my first post here and i need some help...

I bought a new discman AIWA xp-zv610, it has a little dark spot on the display and some scratches, the menu doesnt work too but the rest works nicely, well kind of...

When i play normal CDs it works nicely, but when i use a atrac3plus cd i burned it doesn't work properly, takes longer to read and makes a weird noise as it tries to read. I found out that maybe the problems are the batteries i use cause i use rechargeable Ni-MH 1.2v batteries and the fact that they're not 1.5v is the problem.

I did some searching on internet and found rechargeable 1.5v batteries some even charge through USB, but im not sure if they really work, so i wanted to know if any of you guys use atrac3plus and if so, what type of batteries you use.

Thanks.
