I'm looking for a genuine, original, came-with-your-laptop-new-for-sure battery pack for an ASUS ROG-series laptop from 8-10 years ago. These usually have a part number of A42-G73 or A42-G53, but there can be others. It is an 8-cell rectangular brick. I'm looking for an actual original to rebuild because every single one I've found for sale is a complete piece of crap, even the name-brand and counterfeit genuine models.
I don't expect it to work, but it can't be smashed of course. I'll pay shipping and a few extra bucks if you want.
