3 Usage
Description
This chapter provides detailed instructions on the usage, maintenance, and storage of the X900 battery.
! Notice Please strictly adhere to the usage methods described in this chapter.
3.1 Use
- Please use the dedicated charging equipment to charge this product; the use of other devices for charging is prohibited.
- Depending on your usage needs, you can select between the Standard Charging Mode and Ready-to-Fly Mode on the dedicated charging equipment.
- The Standard Charging Mode can charge the battery to 100%. It can maintain a full charge for 3 days. After 3 days, the charging equipment will wake up the battery, causing it to enter a self-discharge state, which lasts for approximately 2 weeks until the charge level reaches 60%. At this point, self-discharge will stop, and the battery will automatically enter Storage Mode, remaining in this mode until it is awakened again by the charging equipment 3 months later, at which point the battery will be charged back to 100%. If the user does not use the battery, it will continue this cycle.
- The Ready-to-Fly Mode can maintain the battery charge between 85-90%.
- How to Check Battery Remaining Charge: Press the battery button briefly.

Appendix 2 FAQ and Solutions
Description
Problems can be assessed through the comprehensive indicator lights of the battery/charging equipment.
FAQ:
If the battery button indicator light does not illuminate, potential issues could be:
- Battery indicator light malfunction.
- Battery button malfunction.
- Battery has entered lock mode.
- Poor battery communication or over-discharge damage.
Troubleshooting:
For the above issues, combine with the charging equipment by inserting the battery into the battery station to see if it can enter the charging state, and evaluate the following phenomena:
- During this process, if the channel indicator light corresponding to the battery station first lights up yellow and then blinks green slowly, a red light indicates a problem with the battery, specifically, poor battery communication or over-discharge damage.
- If the channel indicator light corresponding to the charging equipment flashes green slowly, this indicates the battery is charging. At this point, check whether the battery indicator light is on:
- If not lit, that indicates a situation: battery indicator light malfunction.
- If the indicator light is on and in a running sequence, then press the battery button and it shows charge level indication, indicating c situation: the battery enters lock mode.
- If the indicator light is on and in a running sequence, but no charge level indication appears when the battery button is pressed, indicating d situation: battery button malfunction.
