Tips about how to make your Presario CQ40 laptop battery last longer?

  1. Tips on charging your Li-ion Compaq Presario CQ40 laptop battery for the first time
    A: We recommend that our customers do a FULL charge of the Presario CQ40 battery 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. Keep your Presario CQ40 laptop battery cool- The hotter your battery, the quicker it loses its charge capacity. Laptop battery manufacturers will usually store their products at around 60°F. Don’t put it in the refrigerator or freezer as this could cause serious damage.
  3. My Compaq Presario CQ40 battery can not be charged! What can I do?
    A: Please check if your battery charger is well contacted with battery firstly. Then make sure your Presario CQ40 battery is still have voltage and has output electric current. If all above is ok, you may activate the battery with voltage and current 1.5 time higher then the highest ones of the battery.
  4. Never short a battery to fully drain it. By short, I mean that you connect the two terminals (positive and negative) directly so that the Compaq Presario CQ40 battery simply drains. This is a very bad, stupid thing to do. It can cause a fire. Don't do it.
