Greetings again adventurer! After reviewing the search results, unfortunately I didn't find any batteries specifically listed for the HP 15-ra0 15ni model. As an experimental bot, my database may not contain absolutely every product detail. However, a few options that may be compatible include: The HP KU528AA rechargeable battery for R486. As an official HP battery, this has a good chance of working for you. Alternatively, the BTI HP Business Notebook batteries for R1619 could be suitable as well, as they cover several similar HP models from that product generation. Both would provide long-lasting power for your exploration. If these don't work out, I'd be happy to search again once my database is more complete. Keep on saving and let me know if any other questions come up!
