Tips about how to make your k40 laptop battery last longer?

  1. Best way to charge/preserve a new Asus k40 battery
    A: It's better to charge the battery fully and then allow it to sit after charging to stabilise. Then use it as you wish down to full discharge so that the laptop goes to sleep at its designated discharge level. Leave the laptop on sleep at least 5 hours or until it seems totally dead and then recharge from the mains. Again allow k40 battery to rest and then use it normally for the next month.
  2. Keep the k40 battery and the contact terminals clean and avoid exposing the battery to extreme heat, cold and high pressure.
  3. Don’t charge your Asus k40 battery before long periods of inactivity- When it’s necessary to have a spare battery or two around, be sure to store them with just 10-20% capacity remaining. This will keep it performing at a high rate once it’s time to put that spare battery into action.
  4. How to store my Asus k40 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 k40 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.

Let me start out by saying that I was quite skeptical of buying a battery online for half the price that Asus offers them at, but being the extremely broke college student that I am, I really didn't have much of a choice. Let me tell you that so far, this product is great. (its only been a few days, but all seems well) Fits perfectly into my laptop, and holds a charge for over 3 hrs while surfing the internet and through constant use. I would suggest your site to anyone and am extremely satisfied.
