Sirius F9P base don't charge batteries

Hi There,

i have one Sirius F9P RTK base. It just don’t charge batteries, it DIScharge instead, even if it’s turned off, when i plug its wall charger. Pls let me know if it’s fixable, otherwise i need a replacement


Have you tried connecting it with the 12v adapter? It seems that the micro usb doesn’t charge the unit.
