laptop battery usage with AC supply


Does the laptop battery get affected by A.C. supply? Does the life of the battery gets affected if run our laptop continuously on A.C. power? All the laptops run on A.C. power when getting fully charged up and still connected to supply mains. Thank you



Answer



There were times when batteries worked with the current passing through them even when the AC adaptor was plugged in and the battery was fully charged. Later the smarter things came, and the system ran the current around the battery when it is fully charged. Even though any battery will lose 20% its capacity every year even if it is constantly full charged. So if you are working always from AC and thinking about to disconnect your battery, charge/discharge the battery to about 50% and then take it away. Store it in the dry and cool place.
