Tips about how to make your RM791 laptop battery last longer?

  1. Tips on charging your Li-ion Dell RM791 laptop battery for the first time
    A: We recommend that our customers do a FULL charge of the RM791battery 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 the RM791 battery and the contact terminals clean and avoid exposing the battery to extreme heat, cold and high pressure.
  3. Avoid letting your battery sit dormant for long periods of time. If you do want to leave your Dell RM791 laptop battery for a long time, charge it at 40%-50% compacity firstly and store it at a cool, dry and clean place. And it's better to take it out to recharge and discharge it each month.
  4. How to store my Dell RM791 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 RM791 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 Dell 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.
