The Dell Inspiron is a laptop computer powered by a rechargeable, lithium ion battery. Time, use and temperature all have an effect on the life of your laptop battery. If you have a lower-capacity battery, frequent charges and discharges can decrease the battery's life prematurely. Exposure to hot or cold temperatures can also decrease the battery's life. Dell laptop batteries are designed to last at least 18 months without a significant reduction in run time. If you notice a shorter run time than usual, check the battery's charge capacity to see if you need a replacement.

Skill level:


  1. 1

    Locate the LED indicator lights on the Dell Inspiron battery.

  2. 2

    Press the button next to the battery's indicator lights. Each illuminated LED represents 20 per cent of your battery's charge. If all five LEDs light up when you press the button, the battery is fully charged.

  3. 3

    Press and hold the button next to the indicator lights for at least three seconds. Each shining light represents the degradation of the battery. If none of the LEDs shine, the battery is in optimal condition. If all five LEDs light up, it's time to replace the battery in your Dell Inspiron.

Tips and warnings

  • Contrary to popular belief, it is not necessary to completely discharge lithium ion batteries between charges.
  • Discharge the Dell Inspiron battery to around 50 per cent capacity if you plan on storing it for longer than 21 days.
  • Remove the battery from any power source if you plan on storing it for more than four days.
  • Do not keep the Dell Inspiron battery in an area where the temperature is below 35 or above 35 degrees C.
