I may get a new battery for my laptop. However I am a bit confused as to the results of my battery wear. I have used a CMD prompt tool and also a downloadable tool that measures my battery wear. Both tools have said my battery wear level is 100%. Specifically:
Full Charged Capacity 47,639 mWh
Designed Capacity 47,639 mWh
Battery Wear Level 100.0%
This leads me to believe the readings are inaccurate. I will perform a battery calibration. I read this is done by:
Charge battery to 100%. Computer can be used during this.
Disable power settings. (sleep, hibernate etc)
Set to hibernate at 5% power level
Unplug laptop and discharge the battery until computer hibernates. Computer can be used normally.
Leave for about 5 hours like this (??)
Recharge to 100%. Computer can be used normally.
Sensors should now produce a more accurate reading.
1: Even as a one off, does this sound too bad for the battery?
2: My computer doesnt randomly cut out at 20% (or any other percentage) so far. Is a battery calibration really necessary?
3: Any other reason my laptops sensors are not indicating any wear what so ever? Dont want to waste money on a new battery if its just sensors misreading.
