Never had acer care center. Installed it, didn't like it and removed it. Today i find my battery drained completely but it was 40% when i turned off my PC and Acer care center says that it needs attention but it was fine yesterday. I have a feeling that the center is at fault. The timing is too suspicious. My windows battery report is saying that my max levels have halved.

Could it be that some parameters changed. I didn't even get an warning from windows that my battery is low. I have that setting at 20% and it didn't turn off when it is critical (I have that option set to 15% battery power)

    After 5 years you may need to replace the battery. Also ACC service may still be running after you uninstalled Acer Care Center, check in Services if you see AccSvc running, stop and disable that. Disable Hibernate and Fast Startup in "Change what closing the lid does" and "Change settings currently unavailable". Change the Power Plan to Balanced and reset Power Plan to factory defaults, don't change the Advanced Power Plan settings. Uninstall Acer Quick Access or disable the USB power on when laptop is turned off option. Boot to BIOS with F2 and reset to factory defaults with F9, save settings and exit BIOS. Close the lid and plug in the Power Adapter, let the battery charge till the amber battery LED turns blue and wait an extra 10 minutes. Boot to windows and verify the battery is 100% charged. Unplug the Power Adapter and disconnect all peripherals, USB devices and monitors. Use the laptop all day till it turns off automatically (2-4% charge left). Close the lid and plug in the Power Adapter and charge again till the amber light turns blue and wait an extra 10 minutes. This is a complete charge cycle required for a new battery so BIOS and MS ACPI battery drivers can register the capacity of the battery. Only need to do this once when you replace the battery or Reset the OS (clean install Windows). If still charge issues replace the battery.

    Full charge capacity typically drops between 10-20% per year even if sitting on a shelf. At 50% remaining of the original design capacity, your battery seems to be doing well since it's likely even several months older than the system's manufacturing date. I seriously doubt installing/uninstalling AcerCareCenter had any affect. IMO, at 50% it's still got quite a bit of life left to it. I've found that changing the default Windows low-battery alarm is buggy, often getting a surprise critical-level shutdown without any warning at all.

    I have done this. My system said that my battery was charged to 139%. It must have lost it's track after years of use so this calibration method helped it to get a bit in order. Now it says it is at about 70% SoH. It was probably a one time problem. The battery physically looks alright. No issues since.

    Sincerely

    Acer Care Center is buggy and the 80% battery charge limit in ACC and other battery apps interfere with Modern Standby protocol in Windows. That battery "calibration" you mention is a misnomer as that applied for the old Ni-Cad batteries that supposedly suffered from "Memory Effect" (debunked). Leave the power adapter plugged in 24/7 and keep the battery always fully charged is my motto. What you need to do whenever you Clean installed Windows or install a new battery is do a full charge cycle (this is not "calibrating") so BIOS and MS ACPI drivers can register the full charge capacity of your battery, failing to do that will result in inaccurate or completely wrong battery statistics in Windows. The correct procedure is as follows: plug in the adapter and charge the battery till the amber battery LED turns blue and wait 10 minutes. Unplug the adapter and work with your laptop all day till it turns off by itself (don't panic, you won't lose data). Close the lid, plug in the adapter and charge till the amber LED turns blue again, wait an extra 10 minutes and boot to windows, verify that the Battery Meter (taskbar) reads 100% charged, if not you have to reset BIOS with F9 in BIOS and save changes, boot to windows and uninstall the two battery drivers (red circle, picture) in Device Manager and repeat the charge cycle procedure above to get the correct 100% full charge reading on the Battery Meter.
