From the Maintenance & Service guide for your laptop model series

4 cell, 70 Whr for use in models with GeForce RTX 3050 or 3050 Ti graphics                               M39179-005
3 cell, 52 Whr for use in models with GeForce GTX 1650 and GeForce RX 6500M graphics      L84394-005

There appears to be a mistake in the Maintenance & Service guide. 

I went ahead and used the PartSurfer and found that the correct HP part number for the battery is  L84394-005

Always search for the battery by the HP Part number, not the generic number. 

SD06XL GENUINE HP BATTERY 11.55V 70.91WH  is a generic part number.

In Amazon.com use HP L84394-005 as the keywords in your search for a vendor with a good price.

Here is one with a reasonable price and a one year warranty.

Hello. yes, that is good, but my question is about if a laptop with ...3xl battery would work on 6xl one. thank you.

Perhaps you should have read your original post again.

This is what your question was.

"Hello, Would SD06XL GENUINE HP BATTERY 11.55V 70.91WH fit and work with 845A2UA computer? "

I provided you with an answer about what HP specifies as the compatible battery for your specific laptop. See the PartSurfer hyperlink in my previous reply.

That is the gospel as far as parts for your laptop go.

[Aleks221]

Hello. Yes, thank you. I know what is the original part of the computer; I have used many other tools to identify it, and I have a bachelor's in technology. my initial question was about those two batteries, which have the same voltage and shape but different capacities and maybe connectors. so that is why I did ask. 

[erico]

The devil is in the details. 

Laptop that have internal batteries are different than those with external batteries in that space is at an absolute premium. 

If you install a battery in your laptop that does not match what the Maintenance & Service guide information that I shared with you had in it, you will be taking a risk in installing it.  That risk will be all yours.

If the dimensions are the same as the original there should not be an issue, but if they differ, that is where the problems begin. If the connectors are different, obviously it won't be a fit.

[Aleks221]

It looks the same. However, I'm not sure about the connector. also, I did ask an Amazon seller, and he told me that those batteries are interchangeable.
