Hello. I recently bought a replacement battery at an authorized HP service center. However, the HP PC Hardware Diagnostics for Windows and the HP Support Assistant apps could not identify the serial/TC number.

 

  • The HP PC Hardware Diagnostics for Windows result was Primary_BatteryCTNumber: abcdefghijklmnop

  • The HP Support Assistant result was CT Number: N/A

 

What does this mean for the authenticity of the battery I got at the authorized HP service center? Is this a common theme with genuine/original battery replacement?

 

Thank you in advance.
