It does not do that. Is there any substitute? Can I use Windows or Mac to substitute the RCMLoader?I mean when you press + button on dongle like attached video. Which color of LED is flashing? If not flashing, your inner battery is dead, and have to disassemble is to replace a new one (quite easy).

EDIT1: Agreed with Coach
I assume I have to buy the battery on aliexpress?
