Tips about how to make your HSTNN-Q21C laptop battery last longer?

  1. Tips on charging your Li-ion HP HSTNN-Q21C laptop battery for the first time
    A: We recommend that our customers do a FULL charge of the HSTNN-Q21Cbattery the first time and then run the laptop on battery power 'til it gets back down to 10% battery left. Then just recharge it and run it however you want.
  2. How can I make my HP HSTNN-Q21C battery last longer?
    A: Firstly, try to avoid frequent full discharging of your HSTNN-Q21C battery. And use the original charger of your HP laptop to fully charge your battery after it automatically powers off. At last, avoid erroneous usage of your batteries such as heavy pressure, short circuit, fall off and so on.
  3. How to make your HP HSTNN-Q21C battery last longer each time?
    A: If you do not need a program any longer, just take those few seconds to close it down and this can greatly help. Instead of your HSTNN-Q21C battery using precious power for a program you are not even using, you can extend its life by just asking it to give you power for what you actually need.
  4. How to store my HP HSTNN-Q21C 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 HSTNN-Q21C 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.
