Computer battery charge and not those of electricity , but several capacity do not know one to choose
7800mAh. However, do keep it for mobile work only and use the old battery when your laptop is connected to the wall outlet. I have my laptop connected to the wall outlet most of the time and that was the cause that the original battery was no longer functioning for mobile use. I got a new battery and when going mobile, I just switch batteries and have decent battery life now.
Thank you very much for your reply , I think is useful , I will consider
