Windows 10: Battery doesn't charge up to full capacity but it in the taskbar it's at 100%

It only charges to 32wH and that value is displayed in the battery report. But it can charge beyond 100% according to the battery report, roughly to about 39wH which was my battery capacity a few days ago. So does anyone know what's going on?

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

Acer battery won't charge

What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
Here's the report file

Generate a battery report. Amongst other things, this should tell you the design capacity of the battery and its current maximum charge capacity. All batteries loose capacity with use so don't expect the charge capacity to be 100% of the design capacity, but for a useable battery it should be well over 50% design capacity.

I second Freebooter's suggestions for checking other reasons the battery may no be charging, but if it's health has deteriorated it may be time to replace it.
