Do you have an eta on when possibly the battery might be available?

MacBook Pro 16" Late 2023

Hello,

I am looking for the battery for the above mentioned system. I know it is not available from you guys as of yet, I was hoping there might be an ETA or any info on when it be available for purchase. Or if you can recommend a reliable place to purchase. I am very familiar with working on Apple laptops and myself an Apple Certified Tech, but I am no longer employed so I cannot order parts directly from Apple to repair my own system. Looking forward to hearing back.

Thank you in advance.

Perry
