Choosing the correct cartridge
Two series-connected 12V 9Ah batteries provide 24V at 9Ah. Check the tray, polarity, connectors and fuse arrangement against the installed assembly. Follow the UPS manufacturer’s replacement procedure; do not assume replacement while powered is permitted.
The 9Ah option has a higher rated capacity than the 7Ah version. Runtime depends on UPS load, cutoff voltage, temperature and battery condition; a fixed percentage increase is not guaranteed.
This high-rate version uses SG129-36HR batteries. Review the discharge tables in the technical document for the required load and duration.
Internal battery documents
These documents describe the individual SG129-36HR battery, not the overall tray dimensions. The installed batteries lie on their sides as shown in the product photos.
