Edit Step 6  ¶ 

  • Remove the battery by lifting the battery from the battery terminal.

  • Be careful to note which end is positive and which is negative. The positive end should be facing away from the PCI slots.

  • It is important to lift the battery as straight up as possible to avoid damage to battery or terminal.

  • IMPORTANT: the first photo shows the correct battery position. The last two photos show the battery facing the WRONG WAY! Remember, the positive end should be facing AWAY from the PCI slots, NOT towards them.

Edit Step 7  ¶ 

  • The area should look like this after the battery is removed.

  • Be sure to properly dispose of the old battery after removal (take it to the nearest hazardous waste center).

  • Only insert LS1425OC 3.6V battery to prevent damage to the logic board.

To reassemble your device, follow these instructions in reverse order.
