orochi v2 mouse problem

My orochi v2 mouse is not working. i got this mouse a couple off months ago and it was working perfectly, in december the dongle broke so the only way i could use this mouse was with bluetooth and the first time i wanted to use it with bluetooth it connected and worked fine since  then. But for some reason today it does not want to connect to bluetooth, i thought it was just the battery so i switched it out but then i remembered i was using the same battery yesterday and it was at 80 or 90 percentage but i still switched it out for a new one. it still did not want to connect the light was not even lighting up or anything every time i switched the battery so i deleted it from bluetooth and then it came back for a couple of seconds working but then it stopped so i did the reset method and it started blinking but then after trying to pair it still did not work. i dont know if i just have to get a new mouse or something cuz the batteries work fine so if anyone could help me let me know sorry if i typed a lot its that i just need help
