How to Test a NOOK Tablet Battery - dummies

By Corey Sandler

Your NOOK Tablet’s lithium ion battery should deliver a nice charge for several years. If the battery fails during the standard one-year warranty period, you’ll have to send it in for repair. Get an idea of how juiced up your tablet is by going to the Quick Settings screen.


Modern high-capacity rechargeable batteries get warm as they’re used. It’s highly unlikely, but a faulty battery could be fire risk. If you believe the internal battery is generating too much heat or is otherwise acting oddly, turn the thing off and contact Barnes & Noble customer service at 1-800-843-2665.

Now, consider things you can do to make the battery last as long as possible:

  • Don’t let the battery become fully run down. Turn off the tablet when you see the low charge alert. Recharge the battery fully before you use it again.

  • Avoid extremely high or low temperatures. Don’t take your tablet to the ski lodge or on your sub-Saharan photo shoot.

  • Don’t let your battery get scorching hot while the tablet’s running. If your tablet is so hot you could fry an egg on it as you read the morning newspaper, do these three things:

    • Carefully unplug it.

    • Turn off the power.

    • Call B&N customer service at 1-800-843-2665.

  • Recharge the battery before a prolonged period on the shelf. If you plan to put your tablet away for more than a week, charge the battery until it’s at least half full. Then turn it off completely by pressing and holding the power button for 3 seconds.

Barnes & Noble urges you to use only the AC adapter and the USB cable that came with your NOOK Tablet.
