Tips about how to make your Lenovo T400 laptop battery last longer?

  1. Why my Lenovo ThinkPad T400 battery's lift time is so short?
    A: Firstly, maybe you have choosed a wrong charger or electro circuit which can not fit your Lenovo ThinkPad T400 battery. Or your Lenovo T400 battery has been overcharged or disovercharged for many times. So make sure you have used the correct charger, and do not overcharge or disovercharge your battery frequently.
  2. Avoid exposure to extreme temperatures. If the system is exposed to extreme cold or hot temperatures, allow the Lenovo ThinkPad T400 battery to warm up/cool down before use and before charging.
  3. Avoid letting your battery sit dormant for long periods of time. If you do want to leave your Lenovo ThinkPad T400 laptop battery for a long time, charge it at 40%-50% compacity firstly and store it at a cool, dry and clean place. And it's better to take it out to recharge and discharge it each month.
  4. How to store my Lenovo ThinkPad T400 battery for a long period of time?
    For extended storage (over 21 - 30 days), these guidelines can better preserve the life of your battery:
    * If it's a new Lenovo ThinkPad T400 battery, store it in its box until you need it. Otherwise, charge or discharge the battery to 40 - 60% capacity using your Windows operating system power meter, then remove it from your system.
    * Store in a standard office environment, away from extreme temperatures.
    * If possible, don't buy batteries until you need them.
