IC693ACC302是一种辅助电池组模块，主要用于为各种系列90-30、系列90-70甚至PACSystems控制器提供延长的内存保留时间。
该电池组的容量为15.0安培小时，与不同型号的控制器一起使用时，能够提供长达15个月至75个月的内存备份时间。这种电池组通过维护CPU的内存，特别是随机存取存储器（RAM），确保即使在电源循环后、维护关闭甚至意外断电的情况下，系统也能继续运行，因为它为易失性存储器供电并防止擦除内存的内容。
IC693ACC302由黑色阻燃ABS塑料制成，配有一根0.6米（2英寸）的红黑两色引线双绞线，带有2针母连接器用于连接电池到模块。电池的外壳尺寸为长145.1毫米（5.7英寸），宽65毫米（2.5英寸），高39.9毫米（1.5英寸）。此外，它带有一个1安培保险丝，用于防止短路或电压过载情况。
The IC693ACC302 is an auxiliary battery pack module designed to provide extended memory retention time for various series 90-30, Series 90-70 and even PACSystems controllers.
The battery pack has a capacity of 15.0 amp hours and is capable of providing up to 15 months to 75 months of memory backup when used with different controller models. By maintaining the CPU's memory, especially random access memory (RAM), this battery pack ensures that the system continues to operate even after a power cycle, maintenance shutdown, or even an unexpected power outage, as it powers the volatile memory and prevents erasing the contents of the memory.
The IC693ACC302 is made of black flame retardant ABS plastic and comes with a 0.6 m (2 in) red and black two-color lead twisted pair with a 2-pin female connector for connecting the battery to the module. The battery's housing dimensions are 145.1 mm (5.7 in) long, 65 mm (2.5 in) wide and 39.9 mm (1.5 in) high. In addition, it comes with a 1 amp fuse to prevent short circuits or voltage overload situations.
