Windows 10: Battery Calibration / Design Capacity reset

Hello all,This is my first question here so forgive me if I overstep.I built a custom battery for my Asus G14 laptop and the cells in the new battery have a 30% higher capacity than the original battery. How I did this was I removed each individual cell from the original battery, kept the stock BMS, and soldered new cells to the BMS. I confirmed everything was working properly before installing. I've left the bottom cover off my laptop to check voltages of the battery. Upon initial charge, I noticed windows would get to 100% but the battery would still charge for a good hour or two at around 3

:)

 

Is my battery wear level high? How do you do a battery calibration?

Hi Antonio,

As for your concern, what battery calibration are you referring to?

It is normal for a battery to lose its original design capacity as time goes by with the charge and discharge cycle. Using any kind of software to do a battery calibration will not help you regain the lost battery capacity. However, you can run the built-in
power troubleshooter. To do this, follow the steps below:

• On the Start menu, type Troubleshooting.
  
• Click View all.
  
• Select Power and run the troubleshooter.

Battery Full Charge Capacity reporting error - More than double Design capacity

I dont use my new (3 months old) Thinkpad often but it is now reporting the Full Charge Capacity as being more than double the Design Capacity which is surely as error.

Full Charge is 121.21Wh while Design Capacity is 50.5Wh. Sorry just cant seem to upload the pic.

I would like to rectify this without doing a battery calibration (battery guage reset) - which most say is bad for the battery.

Is this a Windows error or battery (hardware) error or Thinkpad software error?

Anyway I can reset/reload any software to reset the measurement to an accurate state?

Thank you for your help!

 

My Battery Design Capacity Changed?

I have interesting problem.

In the past my laptop battery life was just 1 hour and then I searced why this thing is so low and, I noticed my laptop battery capacity is 24.000mWh.

I did calibration my battery and this amounth decreased 20.000mWh. After that yesterdey my laptop battery increased 29.000mWh.

My real capacity is 60.000 mWh. That`s why windows is using just %50 portion of my battery.

How can I change this amounth?

Current amounths from diagnostic:

Current Battery Value: 17.850mWh

Full Charged Capacity: 29.184 mWh

Designed Capacity: 29.184 mWh
