Product information

Description

Replacement rechargeable battery designed for Dell PERC controller modules. This compact battery provides 1.8Wh (500mAh) of backup energy to preserve RAID controller cache and configuration data when main power is interrupted. It is intended for maintenance or replacement in compatible Dell PERC systems to restore or maintain battery-backed write operations and ensure continued management of storage arrays.

Advantages

This battery offers a direct form-fit replacement that restores backup power capacity for Dell PERC controllers. With its rated energy and capacity, it helps protect cached write data during short-term power losses and supports orderly shutdowns or data flush procedures. The rechargeable chemistry allows repeated charge/discharge cycles so the controller can rely on the battery for multiple events without immediate replacement.

Suitable for (tasks / use cases)

  • Replacing depleted backup battery in compatible Dell PERC controller modules
  • Maintaining RAID cache protection and preserving configuration settings during power interruptions
  • Server maintenance and component refresh in data center or rack-mounted servers using Dell PERC

When it may not be suitable

This battery is specific to Dell PERC controller backup applications and may not be compatible with other devices or battery housings. It is intended for short-term power backup of controller cache and is not designed to power a server or external hardware for extended periods. For systems requiring long-duration UPS support or batteries with different voltage or capacity, a different solution is needed.

Key specifications

  • Energy capacity: 1.8 Wh
  • Rated capacity: 500 mAh
  • Rechargeable: Yes
  • Intended application: Backup power for RAID controller cache and configuration retention

How to use

Install the battery into the designated socket or holder on the Dell PERC controller according to the server manufacturer’s service manual. Ensure the host system is powered down or follow hot-swap procedures recommended by Dell if supported. After installation, verify controller status in system management tools to confirm the battery is recognized and the backup function is active. Periodically check battery health through the controller management interface and replace when the controller indicates reduced capacity or end-of-life.

What to consider before purchase

  • Compatibility with your specific Dell PERC controller model and server chassis
  • Required energy and capacity for your controller’s backup requirements
  • Installation access and whether professional service is needed for replacement
  • End-of-life indicators and expected service life under your server workload

Usage recommendations

Store and operate the battery within the temperature and humidity ranges recommended by the server manufacturer. Follow Dell’s guidelines for replacement intervals and disposal. After installation, monitor battery condition via the PERC management interface and schedule replacement when capacity falls below the controller’s acceptable threshold to maintain reliable cache protection.
