Make your HP HSTNN OB91 battery last longer:

  1. Should I totally discharge and recharge my HP HSTNN OB91 battery occasionally to make it last longer?
    A: No, discharging and charging does not increase the life of a Li-ion HP HSTNN OB91. And with current Li-ion batteries this practice does not improve the runtime of the battery. This practice is a holdover from the days in which batteries were used.
  2. How do I get the most runtime for a charge?
    A: It is important to choose settings which allow you to obtain the most runtime from your notebook. Examples to consider: timeout settings for the hard drive, Bluetooth, wireless, LCD brightness, etc.
  3. Will my HP HSTNN OB91 battery become useless if I leave it unused for a long time?
    A: Basically, yes. We suggest you to charge or discharge the HP HSTNN OB91 laptop battery to 40 - 60% capacity using your Windows operating system power meter, then remove it from your system. Then Store it in a standard office environment, away from extreme temperatures. However, fully charge and remove battery from HP HSTNN OB91 laptop before leave it unused for a month or longer. It's better to use your battery at least once a week for keeping it works well.
  4. What is the best temperature for battery storage?
    A: Because very hot or cold conditions could affect a battery's performance,you'd better store the HP HSTNN OB91 in a place with recommended storage temperature of 15°C (59°F).
