My laptop battery doesnt last as long as it used to from a full charge. I am considering the calibration process as described here:

 

http://support.hp.com/us-en/document/c00817650

 

My computer is a HP and I intend to use the method for "in use".

 

I also run a health test on the battery:

 

 

Battery:Battery Information
Battery ID 32780 2011/06/29Hewlett-PackardPrimary Manufacturer Hewlett-Packard Serial Number 32780 2011/06/29 Chemistry LIon Long Term 1 Design Capacity 45878 Last Full Charge 45878

 

 

Bit of a discrepancy here. It is not a new battery, far from it. There should be at least a measurable amount of wear. Anyway why would HP advise completely discharging a Li-Ion battery? Thats a big no no isnt it?

 

I will eventually need to buy a new one but that will also need calibrating anyway.

From that article I wager they are wanting you to completely drain your battery to the point that the laptop shuts down.

Yeah I know.  Just wondering if its OK to do or if it will do more harm than good?

 

Recommend a different method?
