It is possible to perform some more advanced servicing tasks with the right tool

13.1.1 Battery replacement

Figure 21 - Important parts when removing battery
On the 18W system the battery is replaced
- Open the housing as described in section 4.1.
- Unscrew black wire from terminal block, pull through the hole in the clear acrylic and use insulation tape to
protect from short circuit on conductive materials
- Repeat with the red wire
- Remove the IDC header strain relief plate shown in Figure 21
- Note the orientation of the IDC cable as it will need to be returned in the same location. Consider a photo to
refer to later. Remove the plate holding the IDC cable in position and carefully leverage off the IDC header.
Remove evenly or the 2x17 header pins may be bent.
- Fully remove the middle spacer on the bottom of the center assembly. Unscrew both ends and completely
remove
- Loosen slightly the remaining spacers to allow the battery to slide out from the end
- To replace the new battery, reverse the steps above. When returning the IDC cable take care to ensure
correct alignment using the red line on one end to the red markings on the 2x17 pin headers

13.1.2 Battery Shipping

In almost all situations, the Ai1 is able to be shipped with the Lithium Ion battery inside, however many airline
regulations prevent the shipping of the battery alone. The Ai1 battery comes in two sizes, 25Ah (which is 92Wh) or
34Ah (125Wh). Many airlines limit the size of the battery to either 160Wh or 100Wh. Confirm with your airline
specifically. An example of the Delta airline requirements, at the time of reference:
