70K80 - Dell 1.6Wh Battery for PowerEdge RAID Controller H710 / H810

Description

The Dell 70K80 is a critical component for maintaining data integrity in servers equipped with Dell's PERC (PowerEdge RAID Controller) H710 or H810. This 3.7V Lithium-Ion battery serves as a backup power source specifically for the RAID controller's onboard cache memory. In the event of an unexpected power failure or interruption, this battery ensures that any data currently residing in the controller's volatile cache is written to non-volatile storage (like SSDs or HDDs) before the system completely loses power. This protection mechanism is vital for preventing data corruption and ensuring the consistency of RAID arrays. Without a functional backup battery, data in the cache could be lost during a power outage, potentially leading to file system corruption or data loss within the array. The 70K80 battery is designed to provide sufficient power for this critical data-saving operation. As an original Dell part, the 70K80 is guaranteed to be compatible and perform reliably with the specified PERC controllers. Regular maintenance and replacement of these backup batteries are recommended as they have a finite lifespan, typically lasting several years. Ensuring the health of this battery is a key aspect of maintaining robust data protection strategies in server environments.
