HP EliteBook 865 G10 (Ryzen 7940HS) Battery: 51 Wh or 76 Wh

 

I would like to buy an HP EliteBook 865 G10 (Ryzen 7940HS) . I would like to replace the original battery (3 cell, 51 Whr, 4.68 Ahr M73466-005) with the bigger one available  (6 cell, 76 Whr, 3.53 Ahr M73470-005).

HP made a Youtube video about how to replace the battery where you can see the 76 Wh battery being replaced:

Their Maintenance and Service Guide mentions both the 51 Wh and 76 Wh batteries but no word about compatibility:
https://kaas.hpcloud.hp.com/pdf-public/pdf_7964739_en-US-1.pdf

I've tried to contact HP about this but I've only received stupid answers:
- "Unfortunately, you would not be able to upgrade the battery because it is soldered onto the motherboard. And all the other hardware components have been designed and fixed on it to work with the 51Wh battery and anything apart from that can cause an issue like short circuit or so."
- "The battery can not be removed."
- "If you change the type of hp laptop battery it takes there is damaging the battery or laptop beyond repair. The reason being that they are programmed to take a certain battery depending on the country they are being sold in."

Clearly the battery is not soldered and can indeed be removed. The AC adapter already takes care of different AC voltages across different countries so that part is bs as well. Unless there is some kind of firmware lock in to prevent it I find it unlikely that replacing the battery could cause any kind of damage if they are physically compatible.
I would love to know your thoughts. The best thing would be to buy a model with the 76 Wh battery but none is available for sale in Italy.

HP Recalls another 100,000 Laptop Batteries

HP is extending its recall of potentially dangerous laptop batteries. HP has recalled more than 100,000 lithium-ion hp laptop batteries from its various notebook models. This recall is expanding from the existing 41,000 battery recall earlier.

The affected laptops were said to include a lithium-ion battery containing Panasonic cells that malfunctioned, leading to "overheating, melting and charring and causing about $1,000 in property damage," the US Consumer Product Safety (US CPSC) report said. The batteries in question could have been used in HP, Compaq, HP ProBook, HP ENVY, Compaq Presario, and HP Pavilion notebook computers. The recalled batteries were in laptops sold between March 2013 and October 2016, the CPSC report stated. Affected laptops could have been purchased at Best Buy, Walmart, Costco, Sam's Club, or another authorized dealer nationwide or online. The average cost of the laptops was between $300-$1700, and the hp laptop batteries were sold from $50-$90.

With this following the Note 7 debacle clearly manufactures need to take a step back and consider saftey over procductivity.
