Boot cycle

Hi,recently I had a boot cycle problem with losing time and date on my razer blade 15 base 2020 laptop and after searches I found out that the problem is with cmos battery, it’s almost 2 months that I’ve bought this laptop and it’s kinda weird to run into such a problem, can you please help me to find the proper cmos battery for my laptop unfortunately razer hasn’t got support in my country(turkey) and I have to fix it
