Razer Blade 15 (early 2020) in boot loop

My Razer Blade 15 (early 2020) lately started acting up. It takes forever to boot and the clock shows the wrong time at the time of boot. From what I can read it would seem that I the problem is the CMOS battery. Does anybody know which battery I should get so as to replace the worn out battery? Very disappointed in Razer. I tried getting in contact with their support department via mail, but they just turned me away on basis of my computer not being covered by warranty...
