Razer Kraken kitty headset

Hello, I have a Razer Kraken kitty headset for 4 years now, and I noticed some problem it had since the beginning, so I live in Algeria, a country where electricity cuts frequently, I left my wireless kitty headset to charge and electricity cutted during it, then the headset stops working no matter what I do, until 5 days pass it works again, this happened so many times and it's always 5 days off then works again, so my question is why is this happening and is there a way for me to make it work immediately?
