cikelempadey 0 Posted May 22, 2012 my dvr's clock battery is a 3v pcb pin type (MS621FE). i read somewhere that i can replace it with normal pc mainboard cmos battery (cr2032). can anyone teach me how to do this exactly since both battery doesnt have same size and usually pc board cmos battery is not soldered onto the board.
