Doubt about 6c battery and internal battery

#1 Post by pictux » Sun Feb 23, 2020 11:41 am

Hi everybody,
just a doubt.
In my T460 there are at the moment these batteries:
*-battery:0
product: 45N1111
vendor: SONY
physical id: 1
slot: Front
capacity: 23200mWh
configuration: voltage=11.1V
*-battery:1
product: 45N1127
vendor: LGC
physical id: 2
slot: Rear
capacity: 23480mWh
configuration: voltage=11.4V

Both are Li-ion 00.
A friend of mine has gave me another battery, that is a 45N1767, 6c, 48Wh
I've found here :
https://pcsupport.lenovo.com/it/en/prod ... compatible
that this battery is supported as compatible, but in the case i see that it is a Li-ion 20.
Also voltage is different between this and the 45N1127 (attached pic).

My doubt is about using this new battery and the internal one.
Is it ok or it can raise any problem due to the different voltage?
Thanks

Yes, it's OK.
You can also use an even bigger 72Wh 68++ battery

I concur.

The nominal voltages of batteries sometimes differ between batteries even of the same generation. It depends a bit on the exact cells used and their configuration, but the laptop knows to pull what it needs.

Li-ion 00 vs 20 has to do with which exact metals/chemicals are contained in the batteries and these are guidelines for recycling, which have nothing to do with how the battery can be used.

Thanks guys!
Interesting to see low level info on them using upower (or other similar tools in linux)
$ upower -i /org/freedesktop/UPower/devices/battery_BAT0
native-path: BAT0
vendor: SONY
model: 45N1111

I'm using right now this new battery, looking forward if the energy-full value is going to change (hope so)

EDIT: energy-full keeps to stay there..

It means that the battery is at half of its life, or I only need to reset that information and let the laptop "discover" again it?
As far as you know, where is stored this value?
Is there a kinda memory in the battery, or is the info saved somewhere in the bios?

Thanks!
