Check your existing battery configuration
Match the complete UPS model and revision, RBC reference, battery voltage, dimensions, terminal type and polarity. Use the supplied photos to check connections and reuse suitable original UPS leads where required. 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.
