Original = 150.5 g
Suspect = 159.1 g
I would've thought a counterfeit might less stuff not more?
New battery charging only up to 96%

Toward the top and the bottom of the report it shows that the Design Capacity of this battery is 28,880mWh (milliWatt-hours). The report shows that the Full Charge Capacity is also 28,880mWh. That's good. The first few lines of the Recent Usage part of the report shows that this battery is indeed charging all the way up to it's design capacity. My interpretation (ignoring for the moment the issue of a seeming 'disconnect') is that the battery is good and fully charging, but Windows battery indicator is 'out of alignment' with this particular battery. I would suggest that a calibration will 'reset' Windows power system so that it knows that 28,880 mWh is 100% and will adjust the charge / discharge levels accordingly. (I know this is written awkwardly, but I hope I'm getting the main point across). EDIT - Basically the whole purpose of the calibration is to set the 100% and 0% of charge capacity so Windows can more accurately show the current charge.
As far as booting to a USB stick, if you have the iso file for the linux distro, you can use Rufus to create the bootable USB stick from said iso. During this process, you can choose whether the USB stick should be UEFI or MBR. If your 'BIOS' on the computer in question does not have 'secure boot' enabled, you should be able to boot from one version or another of the USB stick. EDIT - If I'm talking way below you or speaking in Swahili, let me know, please accept my apologies and I'll try to be more intelligible.

I've got a number of sticks of those and also Passmark's and they are no longer detectable. I do have Ubuntu on a stick I could try.

Could the USB non-detect thing be a simple (but overlooked) BIOS setting? <Just asking...> Like 'enable USB ports' or Enable Legacy USB, or Allow other boot devices.... etc

You'd think, but if's supposed to be the same battery then they should weigh the same. I'd say it's counterfeit.I would've thought a counterfeit might less stuff not more?

Any settings in the bios to prevent overcharging?
No, there is no option to enable/disable USB.
Secure boot/Legacy - yes but either setting makes no difference.
It had worked before the BIOS update, but the update didn't change the features/options offered.

Not in the BIOS, not in Windows.
There was a utility available about the charger to control a schedule of charging, for example from 00.00 - 3.00 no charging. But no option to limit charging capacity. Installed to try but it didn't help.
It might end up that calibration could lock it at the highest charge level as 100% but I haven't gotten to do it yet.
Fair point.
I'll return it if calibration doesn't help and get another one from a different vendor.

Tried this?. From within Windows, press and hold the Shift key and click the “Restart” option in the Start menu or on the sign-in screen. Your PC will restart into the boot options menu.
Select the “Use a device” option on this screen and you can choose a device you want to boot from, such as a USB drive, DVD, or network boot.

I don't know about your model specifically, but HP BIOS Fast Boot only allows for a limited set of boot devices and excludes removable devices, optical and network boot. It's not out of the question that a BIOS update has preset the Fast Boot option.
"the selected boot device failed" - I know there is nothing wrong with them, tried two different sticks
No fast boot option on this one
Something about POST Hotkey Delay ~ which I set to 5 sec (was 0) no difference
On the boot order OS boot manager and Notebook Hard Drive have the selection arrow and it cannot be changed, even after clearing secure boot keys
Had also disconnected the HDD to see whether it would default to the USB stick - no dice. USB 2 ports are accessible in Windows, USB3 port not accessible but I hadn't tried using it before the BIOS update so can't say whether the update killed that too

Don't know about HP, but Lenovo definitely has a battery setting as part of Lenovo Vantage where the maximum and minimum charge are set. Don't charge past 85% and shutdown at 15%, for example. I've run into this on Thinkpads a couple of times.

I wonder if booting into Windows and taking another stab at flashing the BIOS might help. Maybe something went slightly wonky with the update.
This is a cheapy laptop and definitely doesn't offer this feature.
Not sure about the higher grade HPs
Yeah I've tried, it didn't help.
Don't know whether some minor corruption occurred due to the adapter dropping off and on, I did notice the BIOS update pausing when on OFF, then continued when reconnected

Please never pull the power during a BIOS update. If the power is unstable do not do a bios update.
I wouldn't try that on a desktop but in this case the battery was on 90%+ and the reason for the flashing was hopefully it might help with the unstable charging issue
The word "bricked" comes to mind.
