Purchasing a battery for HP ENVY x360 - 15

[Edel_Weiss]

Hello, I want to purchase a battery for my laptop, here are the details:
Product Name: HP ENVY x360 - 15-cn0007nn

CPU: Intel® Core™ i5-8250U (1.6 GHz base frequency, up to 3.4 GHz with Intel® Turbo Boost Technology, 6 MB cache, 4 cores)

Battery: 3-cell, 52.5 Wh Li-ion

Can anyone tell me which battery model should I search for? Where can I buy it from?

This is the battery listed in the Manual which seems not to fit the description in the specs:

(19) Battery (4-cell, 55 WHr, 3.6-Ah, Li-Ion) L43267-005

Service Manual 

See p. 30

This is from eBay Italy for that part no. but lists different compatible models:

In this case I would open the laptop and check the markings on the battery to be sure something is not incorrect here.

Do you see any battery swelling? And where can I purchase this battery model?

It will take a while until I can see the pictures

They just cleared the pictures for me. That battery is not swollen. They get much thicker than that when they swell.

Replacement above. Sorry but it took a while to clear the picture so I could see them.
