Battery Backup Unit
The main board of the imageRAID Controller includes battery control circuitry for
a single cell Lithium Ion battery along with a battery pack mating connector. The
main purpose of battery backup is to maintain the cache memory during brief
power interruptions, but is capable of maintaining the memory content for
several hours, depending on the type and size of the memory.
