Ok, so now we have established that you fitted a replacement battery and that you have a battery and/or a battery driver issue.
I have a ton and a half of music on CD that is not available to buy anywhere digitally. The CDJ appellation is a name, and does not just play CDs. CDJs can play CDs, USB drives, hard drives, interlink with each other, link with a computer etc.I really don't see a point to go back to CDs.
Thank you for telling me that I am wasting my time, the point of forums is to double check for every other factor so to give the most relevant advice. I cannot possibly find out if it's the case or not, until you lay down all the parameters.
If your primary question is ''Can I type track details into standalone controllers?", then there's the user manual accessible online:

And other things such as youtube videos.
