Power Protection and Stability with Fujitsu Batteries

Fujitsu batteries play a vital role in preserving system configurations, maintaining uptime, and protecting data during unexpected power loss. From RAID controller backup units to CMOS and real-time clock batteries, these components ensure continuity and prevent corruption in mission-critical systems. At Direct Hardware Supply, we provide a range of refurbished Fujitsu batteries designed to match OEM specifications for performance and reliability.

Built for Enterprise Continuity

In server environments, Fujitsu batteries are used to support various subsystems such as RAID cache modules, motherboard BIOS settings, and power loss protection circuits. RAID controller batteries, for example, keep write-cache data safe until power is restored – critical for maintaining database integrity and transaction logs. CMOS batteries preserve system settings and timekeeping functions, which are essential for stable server boot processes.

Engineered for Compatibility and Performance

Fujitsu batteries are designed to integrate perfectly with PRIMERGY servers and other hardware platforms. They are manufactured to match specific controller models, ensuring correct voltage, connector fit, and firmware compatibility. Whether supporting a Fujitsu Controller or motherboard within a Fujitsu System, these batteries provide dependable performance across varied environments.

Improve Uptime and Reduce Risk

Batteries in enterprise systems help prevent data loss during sudden shutdowns, allowing for orderly write-back or retention of volatile data. Without a properly functioning battery, systems can experience configuration resets, RAID array failures, or unscheduled downtime. For this reason, battery health should be monitored regularly, and replacements scheduled proactively to avoid service interruptions.

Certified Refurbished Battery Options

Our refurbished Fujitsu batteries undergo careful testing to ensure proper voltage output, capacity retention, and connector integrity. These units offer excellent value and reliability for IT teams maintaining aging infrastructure or replacing failed components. Refurbished batteries are ideal for extending the life of enterprise systems without sacrificing safety or performance standards.

Choosing the Right Battery for Your Hardware

When selecting a Fujitsu battery, consider your server model, battery type (RAID, CMOS, UPS), voltage requirements, and connector format. It's important to match the battery not only to the hardware model but also to the firmware version in use. If you're unsure which model suits your configuration, our team can help identify a compatible unit.
