Question is this battery info normal?

[DJDD01]

My device : Acer predator helios 300 2018 edition with I5 8300h and gtx 1050ti. Battery model: LG PABAS0241231
This is my battery info in HWinfo

Battery Voltage [V]

16.842​

Wear Level [%]

22.5​

is this normal?
The battery voltage seems a bit high to me, it's usually around 12v in most laptops

Also the charging rate was initially 16w and kept on decreasing till it was around 9w when the battery was 95%
is that okay?
My laptop has been acting weird and i'm trying to find out if its the battery or the power adapter
On another post i made regarding this someone said that it's most probably my power adapter but i got it checked today and its giving 19v which it is supposed to so i'm assuming the power adapter is ok.

No way to know if it's normal since you did not list what your laptop or battery model are.

Looks like that battery has an 11.1 v rating, but that is for the battery not for the charge going into it.

But my adapter is of 19v so shouldn't it be 19v then instead of 16 ?
also when disconnected the voltage is still around 14.5 - 15v with charge rate being around -20w
i'm not even sure what is taking up all that wattage.(me assuming that 20 is a large number and that the negative only means discharging) i mean only things running currently on my laptop are chrome and HWinfo and in the tray - Throttlestop (-180mv offset), bluetooth, bitdefender and acer care center.

Edit: i just restarted the laptop (on battery) to see if the voltages change. the voltage didn't change it was still 14.6 but the wattage was -33w and it slowly came down to -23.
