Hello.I hope you are well.I have Acer aspire 7 a715-51g. When I perform battery calibration through Acer Care Center, at the last stage the battery percentage suddenly reaches 100% from 30% within 2 minutes. Of course, since the battery is not actually charged, it discharges again in a very short time in normal use.

    Do not use the Acer Care Centre for any battery calibration or to restrict the battery charge to 80% as it does not work and it will damage your battery, your A715-51G laptop battery should be charging and plugged into the mains power plug through its adapter 24/7 when the laptop is used on the desktop as that is how a laptops battery is prolonged and is kept in good condition. Otherwise and if you use the laptop in a portable way, its fully charged battery should last at least 1.25 -1.5 hours on an 100% charge at normal usage. Good luck and hope this helps you out.

    These are the Aspire A715-51G oem Acer adapters and batteries list for your information, make sure that all these components are in good order and working 100%.
