How to Solve Xhorse Dolphin XP005L Battery Not Charging?

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.
