How to Solve Xhorse Dolphin XP005L Battery Not Charging?

---

Question:
Dolphin XP005L Machine works, as long as it's got power cable, also there's no sign of charging. Without both cables it doesn't work at all. I've left it on charge for 3 hours, but the result is the same. I've also checked the wires on the battery, they are connected.


How to Check Dolphin Battery?
1.Connect power adapter only to power supply, see if blue light on adapter is on

2.When blue light is on, connect power adapter to machine, see if there is a short sound
3.Open charging port, see if cables inside are broken


*Then send SN number to your seller, ensure it is necessary to repair machine or replace battery.
