Replacement Battery for HP Envy

[Johndoenshene]

My laptop began to warp. I need a replacement battery and I can not determine which is the right one to get for my computer. I tried looking at other forums like this one (https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Replacement-battery-HP-Envy/td...) and the links given to this person are no longer working.  Please advise!

"The HP online manual says it's a L09281-855 - the HP parts webpage says this doesn't exist.  Using my product number, it lists six batteries, all of which are totally different - and none have either of the above numbers.

E-bay have about five batteries tagged with the L09281-855 number - but none of them list it as being suitable for my model, and looking at the pictures , none actually have this part number on them.

How am I actually meant to replace the battery?  Any ideas as to the correct way to identify a replacement?"

Thanks
