CyberPower RB1290X6A Key Specs
Battery Chemistry: Sealed Lead-Acid
This chemistry uses electrolyte absorbed in glass mats, preventing leaks. You get maintenance-free operation since you never need to add water. The sealed design ensures safe use in various environments. When shopping for UPS batteries, this type offers reliability and safety. It is a standard choice for restoring original UPS performance without complex upkeep.
Capacity: 12V/9Ah
The 12-volt rating matches your UPS input requirements. The 9 amp-hour capacity determines how long your equipment stays online during an outage. Higher amp-hours generally mean longer backup time for the same load. Compare this value with other cartridges to ensure it meets your specific runtime needs for critical servers or networking gear.
Model: RB1290X6A
This specific model number identifies the exact cartridge design. It ensures you buy a genuine replacement certified for your CyberPower UPS system. Using the correct model restores performance to original specifications. Check this number against your UPS manual before purchasing. It prevents compatibility issues and ensures the unit fits your specific rack or tower model.
Weight: 35.2 pounds
This weight reflects the mass of the lead-acid cells inside. You need to consider this when handling the unit for installation. Ensure your rack or shelf can support this load. Heavier batteries often indicate higher capacity or robust construction. Plan your installation space to accommodate this weight safely during the user-installable setup process.
Dimensions: 19 x 9.4 x 3.3 inches
These physical dimensions determine if the cartridge fits your UPS chassis. The length, width, and height must match the internal bay size. Measure your existing unit or consult the UPS manual before buying. Proper fitment ensures secure mounting and electrical connection. Incorrect dimensions can prevent installation or cause instability in your rack setup.
Design and build specifications
The CyberPower RB1290X6A cartridge is built as a sealed lead-acid unit. According to the listing, the casing is silver and black. This color scheme is standard for server room equipment, helping it blend into existing racks without drawing attention. The design prioritizes function over aesthetics. You are getting a utilitarian object meant for reliability rather than visual appeal in your data center.
The physical dimensions are specific. The listing states the unit measures 19 inches in length, 9.4 inches in width, and 3.3 inches in height. These exact measurements matter because you must verify that your UPS model, such as the OL2200RTXL2U or OL3000RTXL2U, has the correct internal slot. The pre-assembled cartridge is designed to slide into these specific CyberPower systems. If your rack space is tight, you need to account for this length when planning the installation path.
Weight is a practical concern for installation. The listing notes the cartridge weighs 35.2 pounds. This is not a lightweight component. You will need to ensure your UPS chassis can support this load without straining the internal connectors. The user-installable design means you handle this weight during replacement. Proper lifting technique is necessary to avoid injury or damaging the battery terminals during the swap process.
Setup and everyday use
This CyberPower RB1290X6A cartridge is designed for straightforward installation. The listing describes it as a user-installable, pre-assembled unit. You do not need to configure internal cells or connect loose wires. This design allows you to replace the old battery quickly within your UPS system. The cartridge fits specific CyberPower models, including the OL2200RTXL2U, OL3000RTXL2U, and OL3000RTXL2UHV. You must verify your UPS model before proceeding. The physical dimensions are 19 inches in length, 9.4 inches in width, and 3.3 inches in height. The unit weighs 35.2 pounds. You will need adequate space in your rack or floor standing unit to handle this weight and size. The silver and black casing blends into standard server room environments. Daily operation requires no maintenance. The sealed lead-acid chemistry prevents leaks and eliminates the need to add water. You simply install the cartridge and let the UPS manage the charging cycles. The 12V/9Ah capacity provides backup power for connected equipment during outages. When the battery expires, you can use the included reusable packaging to return it to an authorized recycling center. This feature simplifies disposal. The 18-month warranty covers defects in materials and workmanship. This provides assurance for your investment without requiring active monitoring from you.
Check Compatibility And Space
Before you buy, verify your UPS model. This cartridge fits the OL2200RTXL2U, OL3000RTXL2U, and OL3000RTXL2UHV. It does not fit all CyberPower units. Check your existing system’s compatibility list to avoid wasted effort. The unit weighs 35.2 pounds and measures 19 by 9.4 by 3.3 inches. Ensure your rack or shelf can support this weight and footprint. You will need the original packaging for recycling. The listing includes reusable packaging for safe return to authorized centers. Do not discard the box. Upkeep is minimal. Sealed lead-acid chemistry means you never add water or check electrolyte levels. Just install the pre-assembled cartridge. This product restores your UPS to original specs. It is not a standalone power source. You still need your UPS unit to manage power delivery. Compare this replacement against other certified cartridges for your specific model. Ensure the 12V/9Ah rating matches your system’s requirements. Proper fit ensures reliable backup during outages.
