Replacement CMOS RTC Battery for ASUS X58L G60VX F9S UL80V K50AB G60JX by PCRepair

hello everyone now to turn on the computer a few days ago and it didn't boot up it just got to the black screen with american megatrends on it you know what the story was got into the bias and notice the time and date were way back to 2009 it is 2000 sixteen and March so I assumed it wasn't the correct date so I got to the minister boot to the desktop and notice the taskbar desktop time and date was also incorrect which matched the bias did some research online and the most common answer was the battery of the motherboard is on its way out because it's not holding its charge and it's not keeping the settings and the bias and the time of date is not that correct so I've got a saber-tooth z77 motherboard with this armor on normally the battery would be right in there somewhere and you can easily get it out but because of this armor the only way I can see to get the battery errors to have
