Why is this better than hacking in a CR2032?CR2032 batteries are only 3V. Once you use a safety diode, that drops even lower. As soon as the CR2032 voltage lowers with use, your vintage/retro PC will lose it's time and settings. CR2032s do not provide enough voltage for old systems. This battery provides ~4.5V, and AAA batteries have 3x the capacity of CR2032 cells. What you will receive:
Remote battery board + Backer
3 x AAA batteries(Brand may vary)
2 x 100mA fuses (one installed, one spare)
12" and 28" cables (Might have red and black OR yellow and white wires, depending on availability)
