Check your existing battery configuration
Match the complete UPS model and revision, RBC reference, battery voltage, dimensions, terminal type and polarity. This is a battery-only package, not a complete prewired cartridge. Reuse suitable original leads, fuse assemblies and trays; these are not included. Follow the UPS manufacturer’s replacement instructions. The UPS is not included.
The supplier rates each battery at 9Ah. Runtime depends on load, temperature, battery condition and UPS settings; capacity alone does not promise a fixed runtime increase.
