Orochi V2 keeps disconnecting

Greetings! A decent while ago I bought myself a new Orochi V2, but as of a couple months ago I have been having some issues with the mouse. It seemingly just disconnects at random times, even when it's being used like when I am in the middle of a game. There is no way to turn it back on unless I open the lid and take the battery in and out again, only then will it turn on. It can't be the fault of the batteries because it is very unlikely that my brand new batteries deplete so quickly. As they sometimes tend to disconnect after even less than a day of use. Any help would be appreciated, Thanks!
