Replacing The KWIK Mobi Battery & the Mobi Pen Battery

Some of you have had your Mobi now for a couple of years so at some point, if you haven’t already done so, the batteries will have to be replaced. There are two batteries that will eventually need to be replaced. The Mobi pen battery is $4.00 from eInstruction and the part number is IW-A-629-039-000. It's a GP (Gold Peak) 1.2 volt battery. To get to the battery, locate the square little button on the back of the pen just above the 2 silver rings. Use a key or something to press the button in a little. Slide the pen apart and you will see the battery. I have also found that if your pen is not working and you have definitely charged it, you might just need to take this battery out and use a pencil eraser to clean the contacts. When you are charging the Mobi and the pen, be sure you see the little pen charging icon. This is a little square with a line at an angle through the top. If you do not see the little square constantly filling and emptying, then the pen is not being charged. It is very possible to charge the Mobi and not charge the pen. You may just have to push the pen down all the way into the pen slot of the Mobi. You also may just have to turn the pen around a bit in the slot. In any case, be sure you see that the pen charging icon is displayed.

The KWIK Mobi also has a battery of course and eInstruction charges $35.00 for it. The part number is CB-A-629-038-000. eInstuction also charges $5.00 for shipping and handling. The KWIK Mobi battery is accessed from the back. Use a small Phillips head screwdriver to remove the screw and then you can remove the battery cover. It is a rectangular shaped lithium-ion 3.7 volt battery. Just be sure that the gold color contacts are facing towards the upper left corner when placing it back in the battery compartment. Again, be sure you see the Mobi battery icon constantly filling and emptying when you are charging it.
