Who it fits

Good fit for

You should choose this cartridge if you own a CyberPower OR2200PFCRT2U UPS. The pre-assembled design makes it ideal for users who want to replace weak batteries without complex wiring. The sealed lead-acid chemistry provides robust power-to-weight ratios. It suits those who need a maintenance-free solution that does not require fluid replacement. The included recycling packaging is helpful for environmentally conscious users. This option works best for restoring original equipment performance rather than upgrading capacity.

Who should skip it

Look elsewhere if your UPS model is not the OR2200PFCRT2U. This cartridge is not universal and will not fit other CyberPower units. You should skip this if you need lithium-ion batteries instead of lead-acid. The 9Ah capacity per cell is fixed and cannot be increased. Users seeking a smart battery monitoring app will find none here. The warranty covers only defects, not normal wear over long periods. If your unit requires a different form factor, this 24.3-pound cartridge will not work.

Verdict: This cartridge is a direct replacement for specific CyberPower UPS models. It offers a simple, maintenance-free upgrade path for degraded batteries.

Key specs for this cartridge

Battery Chemistry: Lead-Acid

This cartridge uses sealed lead-acid cells. This chemistry is standard for many UPS units because it offers reliable surge current delivery. You get a robust power-to-weight ratio that handles short power outages effectively. It is maintenance-free, so you do not need to check fluid levels. This makes it a practical choice for users who want a set-and-forget solution for their specific CyberPower models.

Configuration: Four 12V/9Ah batteries

The unit contains four individual batteries, each rated at 12 volts and 9 amp-hours. This configuration provides the necessary voltage and capacity for compatible UPS systems. The 9Ah rating indicates how much energy is stored, influencing runtime during a blackout. You benefit from a pre-assembled cartridge that restores full function to your unit without needing to source individual cells separately.

Weight: 24.3 pounds

The entire cartridge weighs 24.3 pounds. This weight comes from the dense lead-acid cells inside. You should ensure your UPS chassis can support this mass without stress on mounting points. Heavier batteries often correlate with better surge handling capabilities. When comparing options, note that this weight is typical for this capacity class, ensuring stability during operation.

Dimensions: 12 x 8.1 x 2.6 inches

The cartridge measures 12 inches long, 8.1 inches wide, and 2.6 inches high. These exact dimensions are critical for fitting into specific CyberPower UPS models like the OR2200PFCRT2U. You must verify these measurements match your existing bay to ensure proper installation. The compact height allows it to sit securely within the unit without interfering with internal components or airflow paths.

Physical Design and Build Quality

The cartridge measures 12 inches in length, 8.1 inches in width, and 2.6 inches in height. It weighs 24.3 pounds. These dimensions are designed to fit directly into compatible CyberPower units, such as the OR2200PFCRT2U. The compact profile allows it to sit securely inside the chassis without taking up excessive space. The weight suggests a dense internal construction, which is typical for lead-acid batteries that need to deliver high surge currents.

According to the listing, the unit features a white finish. This color is standard for internal components and does not affect performance. The cartridge is pre-assembled, meaning you do not need to connect individual wires or secure loose cells. This design choice simplifies the installation process significantly. You can remove the old unit and slide this new one into place quickly. The maintenance-free sealed lead-acid design means you never need to check fluid levels or add water. This reduces long-term upkeep.

The packaging is reusable, allowing you to return expired batteries to recycling centers easily. This feature supports proper disposal of the lead-acid cells. The overall build focuses on durability and ease of use. You get a robust power-to-weight ratio that handles short power outages effectively. The physical design ensures the batteries stay protected inside the UPS while providing reliable backup power when needed.

Setup And Everyday Use

Setting up this replacement cartridge is designed to be straightforward for you. The unit arrives as a pre-assembled module, which means you do not need to wire individual cells or configure internal connections. This design choice simplifies the installation process significantly. You simply remove the old battery pack from your CyberPower OR2200PFCRT2U unit and slide this new cartridge into the designated slot. The physical dimensions of 12 inches in length, 8.1 inches in width, and 2.6 inches in height ensure it fits the internal bay without modification. The total weight of 24.3 pounds is substantial, so you should handle it with care during the swap to avoid strain. Once installed, the system recognizes the new power source immediately. Daily use relies on the sealed lead-acid chemistry to provide stable voltage during outages. Because the battery fluid is maintenance-free, you do not need to check levels or add distilled water. This eliminates routine upkeep tasks. The four 12V/9Ah cells work together to deliver high surge currents when needed. You can trust the system to handle short power interruptions without manual intervention. When the batteries eventually deplete, the reusable packaging allows you to send the expired unit back to recycling centers conveniently. This feature supports responsible disposal without extra effort. The 18-month warranty covers defects in materials and workmanship under normal conditions. This provides a clear timeframe for performance assurance. You get a reliable power backup solution that requires minimal interaction after the initial installation. The focus remains on consistent energy delivery rather than complex management.

Check Compatibility Before Installing

Before you install this CyberPower RB1290X4H cartridge, verify your UPS model. The listing specifies compatibility with the OR2200PFCRT2U. Using it in an unsupported unit may cause errors or failure to power. Check your existing UPS manual or label to confirm the exact model number. This replacement is designed for systems that use four 12V/9Ah batteries. If your unit requires a different capacity or cell count, this cartridge will not fit or function correctly.

Upkeep is minimal because the sealed lead-acid chemistry is maintenance-free. You do not need to check fluid levels or add water. However, you should recycle the old batteries responsibly. The packaging is reusable for this purpose. Consider this option alongside other replacement cartridges on this page. Compare dimensions and weight to ensure your UPS bay can accommodate the 24.3-pound module. Proper fit ensures stable power delivery during outages.
