Thank you so much for your comment. You have to do it with a scanner

Thank you so much for your comment. That is why you have to register your battery. When you register the battery you are restarting a count. The higher the count the hardest the system charges the battery as the battery gets weaker and weaker. So registering your battery should solve your problem.
