Pavillion 15CW Battery weak and BIOS update

[VFRRaider]

I am going to replace the battery in my 15-cw1017na with  HP 15 Series Battery 

First, I would like to update my BIOS from F.47 to F.55 however, when using the wesbite installer, a box will pop up bottom right and state download failed?

I am using the informtion supplied via this link HP Pavillion 15 updates

Replace the battery first!!

Only use HP genuine battery with an HP logo for best results.

Generic batteries can give unexpected and undesired results.

Hi Erico

My apologies for the late reply and thank you for your help.

I've come across 2 retailers, one HP and Harvey Norman with the L11119-855 part number.

HP Battery 

Harvey Norman Battery 

I take it there is no difference?

[erico]

No worries.

I suggest that you read my last reply again. I explained why using the battery that has the HP logo is a better idea. It meets the specifications that HP required for your laptop.

Both have the HP logo, however I'll purchase it directly from HP just to be sure. 

Thanks again
