HP ENVY Notebook battery replacement

[anpar]

Hi,

The battery of my HP ENVY Notebook (P7T97EA#UUG) now deserves to retire and I thus would like to replace it with a new one.

When I look for batteries on the HP Parts Store using my S/N (CND54314HF) and my P/N (P7T97EA#UUG), I get 6 different results (leaving aside those out of stock) :

• Part: 593553-001. Battery (Primary) - 6-cell lithium-Ion (Li-Ion), 2.2Ah, 47Wh (MU06047) 
• Part: 687945-001. Battery (Primary, Long Life) - 4-cell lithium-ion (Li-Ion), 3.55Ah, 52Wh (BT04052XL-PL) 
• Part: 717376-001. Battery (Primary) - 3-cell lithium-ion (Li-Ion), 4.5Ah, 50Wh (CM03050XL-PL)
• Part: 756744-001. Battery (Primary) - 4-cell lithium-ion (Li-Ion), 3.0Ah, 44Wh (VI04044-CL)  
• Part: 767068-005. Battery pack (Primary) - 3-cell lithium-Ion (Li-Ion), 3.25Ah, 36Wh (PE03036XL-PR) 
• Part: 807956-001. Battery pack - 3-cell lithium-ion (Li-Ion), 2.8Ah, 31Wh (HS03031-CL)  

However, these batteries seem to have different dimensions and shapes, which makes me think that they are not all compatible with my laptop. How can I known which ones are compatible with my laptop? Subsidiary question: which one, among the compatible ones, is the best in term of autonomy?

Thank you,

AP

EDIT: I just noticed on the back of my laptop that my battery model seems to be "RMN TPN-C120". I guess this is the one I need then?

Hi,

Well, none of those batteries is the correct one. The part number for your battery is 816238-850 as we can see on page 28 of the service manual 

It is not available in the HP parts store in your country. You can find at reseller:
