Who it fits

Key specs for this UPS battery

Battery Chemistry: Sealed Lead-Acid

This chemistry type provides high surge currents when your computer needs extra power during a grid failure. It offers a strong balance between weight and energy storage. You do not need to add fluid or perform maintenance. This makes it reliable for standard desktop setups where consistent backup is more important than extreme weight savings.

Capacity: 12V/7.2Ah

The voltage matches your UPS system requirements, while the amp-hour rating determines how long your gear stays on. A 7.2Ah capacity supports moderate loads for a short duration. This is sufficient for saving work and shutting down safely. Compare this rating when selecting replacements to ensure your specific UPS model receives adequate runtime.

Dimensions: 8 x 6 x 3 inches

These physical measurements define the space the cartridge occupies inside your UPS unit. You must verify that these dimensions fit the internal bay of your specific CyberPower model. The compact form factor allows for efficient use of available space. Check your current battery size to ensure a direct swap without needing modifications or extra adapters.

Weight: 13.4 pounds

The total weight includes both batteries and the cartridge housing. This mass indicates the density of the lead-acid cells inside. Heavier units often correlate with robust construction and reliable power delivery. Consider this weight if you need to move the UPS or if the unit sits on a shelf with limited load capacity.

Warranty: 18-Month

This coverage period protects against defects in materials and workmanship. It gives you eighteen months of assurance from the date of purchase. This duration is standard for replacement cartridges. Use this timeframe to evaluate the longevity of the new batteries. It provides peace of mind while you wait for the next maintenance cycle.

Physical Design And Build Quality

The cartridge is constructed from durable materials designed to house two sealed lead-acid batteries. This chemistry choice ensures you get high surge currents when your equipment needs a power boost during a grid failure. The design is maintenance-free, meaning you never need to replace battery fluid or perform routine checks. This practical feature keeps the unit reliable over time without requiring technical intervention from you.

According to the listing, the physical dimensions are six inches in length, eight inches in width, and three inches in height. The total weight is 13.4 pounds. These measurements indicate a compact form factor that fits into standard UPS chassis. The black finish is purely cosmetic and does not affect performance. The pre-assembled nature of the cartridge allows for quick and convenient installation directly into your UPS system.

The product is user-installable, which simplifies the replacement process significantly. You can handle the swap without professional help. The packaging is reusable, allowing you to return expired batteries to recycling centers easily. This design consideration supports responsible disposal. The layout is straightforward, with no complex controls or displays to manage. It is a simple, functional unit focused on restoring power protection for compatible CyberPower models.

You simply install the cartridge into your compatible CyberPower UPS system. The listing specifies compatibility with the CP1200AVR and CP1285AVRLCD models. Before purchasing, verify your specific unit matches one of these models to ensure proper fit and function.

The physical dimensions of the cartridge are 8 inches in width, 6 inches in length, and 3 inches in height. It weighs 13.4 pounds, a manageable weight for handling during installation. The black casing houses two sealed lead-acid batteries, each providing 12 volts and 7.2 amp-hours of capacity.

Before You Buy This Replacement

Before installing the CyberPower RB1280X2D, verify your UPS model. It fits the CP1200AVR and CP1285AVRLCD units only. Using it with an incompatible device will not work. The cartridge holds two 12-volt, 7.2 amp-hour sealed lead-acid batteries. These provide high surge currents and require no fluid maintenance. You do not need to add water or check electrolyte levels. The unit arrives pre-assembled, allowing quick installation into your existing system. Ensure your workspace is clear for the 13.4-pound cartridge. You will need a screwdriver or tool to open the UPS casing, depending on your model. This replacement restores power protection for aging units. It sits alongside other replacement cartridges but is specific to CyberPower hardware. Consider your UPS age and battery health.
