In this case we should focus on one improtant thing:
How long time do we use the device from the electric network?
If we use our notebook on network you should charge the battery fully and then remove it.
Weekly we should use the battery until it goes down to 10% then follow the instructions mentioned before.
If we use the device mainly with its battery, try to charge it fully and use it until it discharges also fully, then we can recharge it when it is not in use.
With this method we can save up couple of 10.000HUF!
A battery's price stars at 15.000HUF but the original versions might cost more!
A newly bought 2-3 year-guarantee notebooks producers only give 1 year guarantee on batteries! We should inquire this when buying!
