Artics Pro Wireless - Replacement Batteries

Hello,

I'm currently in desperate need of replacement batteries for my Artics Pro Wireless headset and Steel Series advised me they no longer sell them. Unfortunately both my batteries just stopped charging within 2 days of each other which leaves me with no headset. I've checked on Amazon and all the ones listed are off brand with awful reviews. Has anyone bought them elsewhere and had any luck? If anyone knows a solid place to buy them I'd be greatly appreciative! Thanks!
