And now this: As a substitute for a slightly aged battery for my HP EliteBook 8540w I ordered the product above. It came with an initial charge of 55% and could be recharged during operation at 100%. After the battery has been stressed twice to shutdown the computer and recharged.
That was the "calibration". Are first fully charged for these needs the battery to the display by 100 percent and are then removed from the charger. Subsequently, through the Control Panel of the operating system, the power options to conserve power during battery operation, deactivated. Now the notebook has to run until the battery is completely discharged and the unit shuts down on its own. Now you have to connect the notebook to the power adapter and restart. The battery gauge is now calibrated and indicates the correct term. After calibration, you can adjust the original Power Options again to reduce power consumption.
In all of this, it turned out that the acquired "PELTEC @ Premium Notebook Laptop Battery" will give me in my EliteBook no disappointment. I am - as far as is possible - already sure that he is the original battery par. In a few weeks I'll resent how the battery has been proven.
