Windows 10: New battery with more capacity won't charge past the old capacity

Hey Folks,


yesterday I changed the battery of my laptop. I replaced the old 60Wh battery with a new and bigger 96Wh battery. New battery is an OEM part - was offered for models without a 2,5 HDD.


First of all:

It works. Windows noticed the change of battery and also the new capacity - as the battery report shows.


battery report: https://1drv.ms/u/s!Aq6hUdxlPQvOgmwLp3UWFXCgE2f9?e=UiQ1YN needs to be downloaded to shown correctly


BUT:

The new battery only charges to 62%, which in my case is 100% of the old batterys capacity.

I can't use the calibration because Windows won't recognize a full circle if it is not charging to 100%.

I tried the troubleshooter: nothing.

I tried the remove and reinstallation of the APCI battery driver: nothing

I also looked up in the BIOS, but I don't have a battery option.


QUESTION:

How can I teach Windows, that it can charge to the full recognized capacity of the new battery?


Note: Windows was completely new set up a month ago.


Thank you for your help

Battery FULL CHARGE CAPACITY Reset

Yves,

"Full charge capacity" means the capacity that the battery is managing to achieve. It is not a limit set by Windows or anything else; it is merely a reading of what the battery can actually do. You can use the comparison of Full charge capacity with Design
capacity to decide when to buy a replacement battery [I do the same regularly].

Full charge capacity will always decrease over time as the battery wears out. This is a chemical phenomenon not a Windows-imposed characteristic.

Windows display of "Fully charged [100%]" means - the battery is currently at 100% of what it is able to achieve. In other words, "Fully charged [100%]" is relative to Full charge capacity.

Sometimes, you can find that cycling through the battery three times** can improve the Full charge capacity a bit.
On at least one of my batteries, the maker recommends doing this every three months. But doing so is using up even more of its remaining life so you can complete this procedure only to find that you are worse off afterwards.

** In other words, loop through this three times -

• remove the AC power
• use up the whole charge by using the computer
• recharge fully

Battery FULL CHARGE CAPACITY Reset

I have a laptop where the Battery report tells me that the battery FULL CHARGE CAPACITY is much less than its DESIGN
CAPACITY.

I would like to know if there is a way to reset this setting somehow so that Windows can try to fully charge the battery, instead of stopping the charge at what is currently known as the battery FULL CHARGE CAPACITY.

Right now, the numbers are:

2017-05-23
5 441 mWh
48 669 mWh

which results in only a few minutes of battery usage.

Using the CPUID HWMonitor tool, I can see that the battery charge actually stops at 5441 mWh, instead of continuing, and Windows report the battery as being 100% charged at that level, even if it is only at 11% capacity.

So, can anyone provide a method to reset the battery FULL CHARGE CAPACITY to its DESIGN CAPACITY so that Windows can re-evaluate the true battery capacity, as if it was a brand new battery.

Thanks.

 

Windows 10 battery percentage of design or full charge capacity?

Is the battery indicator in Windows 10 a percentage of the design capacity or the current full charge capacity of the battery ?

ie. if my battery capacity dropped from say, 60mWh to 30mWh from wear, would the indicator show 50% or 100% when the battery is fully charged at its current capacity of 30mWh ?

EDIT: to describe my case, I have an XPS 13 9350 whose battery has a design capacity of 56mWh. over the past few weeks, the battery percentage in windows stops at 55 with "plugged in not charging". running

shows that the current full charge capacity is about 41mWh, meaning at 55% I'm getting about 20mWh on a "full" charge. the surprising thing is Dell Command Power Manager shows my battery to be in excellent health.
