If the battery has already had problems like the run time obviously being shortened and serious memory effect, how can we remedy it? Try below methods:
Firstly, enter into BIOS and shut the electrical power manager. Because many laptops have electricity saving mode, over-low voltage may lead to laptop
shutting down automatically. Then turn on the laptop again. Press PAUSE before getting into WINDOWS. Let it stay in WINDOWS menu until electric power
getting used-up which will cause the laptop to shut down. Repeat this process three times before recharging it. The above method is usually very effective.
2) Why there is no need for us to remove the battery when we use external electrical power?
There is chip on the main board to prevent overcharge. When it has been charged up to 100%, charging control chip(PET) will stop the charging.
Dont worry about any damage to the battery.
3) How to store battery when it is not in use for a long time? It should be fully charged or discharged?
Storing the batteries at full discharge for long period of time will have the Dell Studio XPS 1340 battery cells lose their activity, even have the control circuit protection self-closed
which resulted in its inability to be re-used. Storing the batteries at full charge will have battery safety jeopardized. The best way to store the batteries
is to keep the batteries at cool and dry places at optimal temperature of about 20 degrees with only about 50% capacity remained. Off course, getting
the battery out every month for use is the best way to keep the Dell LATITUDE E5510 battery at excellent storage state and battery power free from flowing away completely
