Dell C291H 400mAh 2.5V Lithium-Ion Raid Controller Battery Backup

Product Description

The Dell C291H is a compact Lithium-Ion battery designed to serve as a backup power source for specific Dell RAID controller cards. Its primary purpose is to provide a temporary power supply to the RAID controller's cache memory in the event of an unexpected loss of main system power. This function is critical for preventing data corruption or loss that could occur if the controller's volatile cache is not properly flushed before power is removed. With a capacity of 400mAh and a voltage of 2.5V, this battery is engineered to deliver sufficient power for the RAID controller to complete essential operations, such as writing any pending data from the cache to the disk drives. This ensures the integrity and consistency of the data stored on the RAID array, offering a crucial layer of protection for valuable information. The C291H battery is an important component for maintaining data reliability in servers and workstations that utilize compatible Dell RAID controllers. Its presence ensures that data transactions are not compromised by power fluctuations or outages, providing peace of mind for users who depend on the continuous availability and safety of their data.
