Product Description
The Dell T04JJ battery is a small, rechargeable Lithium-Ion power source with a voltage of 3.7V and a capacity of 500mAh. This battery is specifically designed to serve as a backup power source for the cache memory on Dell's PERC H710 RAID controller. In RAID controllers, a battery backup unit (BBU) or flash-backed write cache (FBWC) is crucial for protecting data in the event of a power outage. When power is lost, the battery allows the controller to write any data that is still in its volatile cache memory to non-volatile flash memory, preventing data loss or corruption. This 3.7V, 500mAh battery ensures that the PERC H710 RAID controller can maintain data integrity during unexpected power interruptions, which is vital for server stability and data protection in enterprise environments. The T04JJ part number confirms its compatibility and intended use with the specified RAID controller.
