Thank you very much for your trust in using our laptop batteries. Please read the user's manual carefully before using the battery, it shows you how to use and maintain the batteries properly. Battery is a consumable electronic product with limited life, but correct use, proper charging and discharging as well as good storage would significantly prolong the laptop battery life.
Calibrating Your Computer's Battery For Best Performance
The battery has an internal microprocessor that provides an estimate of the amount of energy in the battery as it charges and discharges. The battery needs to be recalibrated from time to time to keep the onscreen battery time and percent display accurate. Your should perform this procedure when you first use your battery and then every few months thereafer.
Make Proper settings for "POWER" option: click right key of your mouse in the blank screen, choose "Properties" - "Screen Saver" - "Power" - "Power Schemes" - "Portable", and "When computer is" "Running on batteries", tick "Never" for all options. Under "Alarms" option, don't tick "Low battery alarm" and "Critical battery alarm" functions, and then choose "Apply" and "OK" to save the settings.
Disconnect the power adapter and use your battery until laptop shuts down.
Plug the power adapter in and fully charge your computer's battery to 100%. Upon initial use (or after a prolonged storage period) the battery may require three to four charge/discharge cycles before achieving maximum preformance. The charging process should last at least around 14 hours.
You have to first discharge your battery until laptop shuts down before you recharge it to 100% for calibration. After that, you can connect and disconnect the power adapter when the battery is at any charge level.
Tips: When the battery reaches "empty", the computer is forced into sleep mode. The battery actually keeps back a reserve beyond "empty", to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, any open files could be lost.
Batteries may be damaged if stored for prolonged periods with a closed circuit. If the battery will not be in use for a month or longer, it is recommended that it be removed from the device, 60%~80% charged and stored in a cool, dry and clean place. A charged battery will eventually lose its charge and be damaged if unused. It may therefore be necessary to recharge the battery after a certain storage period. Surely it would be great if you can use the battery once in a month to ensure good storage status.
Do not short-circuit. A short - circuit may cause severe damage to the battery.
Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
Do not expose the battery to heat sources and moisture or rain.
Keep battery away from fire or other sources of extreme heat.
Do not incinerate. Exposure of battery to extreme heat may result in an explosion.
Don't try to disassemble, repair or change the battery pack which would cause over-heating or fire. Corrosive alkaline solutions or other electrolyte leakage would lead to fire or personal injury and death.
Don't puncture the battery by sharp materials.
