Ztac Headset Issues

[matas17]

So I've been running my ztac headset mounted on my fast helmet for over a year now and recently i noticed that it turns itself off after like 5-10minutes during the game. I was using few days ago during night game with brand new battery and noticed that it kept turning off. Did anyone ever ran into similair issue or found a way to solve it. I have checked the battery contacts inside the headset and the seem good no corrosion or anything at all.
