Does the Bond II have an internal battery?
There is no internal battery on the The Bond II product family.
The compact design of the Bond II prevented the inclusion of an internal battery with any significant capacity inside the chassis.
Why does my Bond II's chassis show Battery, CHG, and FLT text and LEDs?
The original design of the Bond II's chassis included some elements from the Cube's chassis, including text on the chassis for Battery, CHG, or FLT, and corresponding LEDs below that text.
However, these LEDs will not illuminate when a Bond II is connected to an external power source using either a 2-pin locking connector or a micro USB connector.
All currently-shipping Bond II units have a corrected chassis with those LEDs and the text omitted, but older Bond II units could still have the previous chassis design with those items present.
