Lithium-Ion batteries have become the power source of choice for many laptop manufacturers
due to the battery's ability to handle higher current drain in laptops. They also don't have the "memory effect" found in nickel-cadmium batteries, which can prevent a full charge to the batteries after a given number of charge cycles, depending upon quality controls in place for the particular manufacturer. Li-Ion batteries can provide two to three years of heavy use before they need to be replaced, if they are cared for properly.
Charge your laptop battery when it reaches a 25 percent discharge level according to your Dell laptop battery level indicator. Li-Ion batteries last longer when you prevent the charge level from reaching 0 volts repeatedly.
Calibrate the accuracy of your laptop's battery metering circuitry to your aging battery to keep it as accurate as possible. Simply allow the battery to discharge completely, all the way down to 0 Volts, once every 30 charges. This calibration is not needed more frequently than once every 30 charges.
Keep your Acer battery laptop as cool as possible. High heat reduces the longevity of Li-Ion batteries. Keep your laptop in a well-insulated laptop bag or case when not in use to prevent exposure to direct sunlight.
Store your Li-Ion battery at a 40 percent charge if you won't be using it for weeks or months, and try to store the battery at 0 degrees C. If you can't maintain this temperature, keep the battery in a cool dark location such as a basement or closet.
Place your Li-Ion battery into your laptop and use it for just two or three minutes once per month, if you are storing it for longer than a 30-day period, to allow movement of ions in the Apple macbook battery. This will help maintain the health of the battery cells.
Take the battery out of your laptop if you will be keeping the computer plugged into the power source for long durations.
Moisture damages all battery types. Use care to ensure your battery isn't exposed to areas with excessively high humidity.
