Replacement for Electrolux Osiris and RX9

The Cameron Sino OSBP72LI is a new lithium polymer battery built to match the original specifications for Electrolux Osiris, RX9 and Saugroboter RX9-1-SGM robotic vacuums. It delivers a capacity of 2600mAh at 7.2V, providing 18.72Wh of energy. The pack measures 77.10 x 58.80 x 25.52mm and weighs 120g. A fully decoded chip ensures communication with the vacuum works the same as the factory cell.

Sustained run-time and protection

The 2600mAh capacity determines how long the robot can clean on a single charge under normal household conditions. Integrated circuitry guards against overcharge, over-discharge, over-voltage and short circuits, so the cell maintains stable output through repeated cleaning cycles. The manufacturer notes that a new pack reaches its best performance after two or three complete charge and discharge cycles.

7.2V 2600mAh lithium polymer form factor

The single specification that decides fit is the 7.2V 2600mAh lithium polymer pack in the exact 77.10 x 58.80 x 25.52mm housing with the OSBP72LI part number. Buyers whose vacuums require a different voltage, capacity or physical layout cannot use this unit. Always verify the original battery part number before purchase.

Questions about this item

How much heat does the 7.2 V 2600 mAh lithium polymer pack generate during a full day of robot vacuuming?

The battery is designed to match the original specifications and includes overcharge, over-discharge, over-voltage and short-circuit protection, which keeps temperature rise within normal operating limits for the Electrolux Osiris and RX9 series.

What must I already own for this OSBP72LI replacement to work in my cleaner?

You need a compatible Electrolux Osiris, RX9 or Saugroboter RX9-1-SGM robot vacuum that originally used part number OSBP72LI or S91-0400410-SU2, plus the standard charging dock supplied with that robot.

Will this 77.10 × 58.80 × 25.52 mm pack fit and function in an older RX8 or RX7 robot I still use?

The manufacturer lists RX8, RX8-1-4SWN, RX8-1-4WN, RX7-1-TM and several Electrolux part numbers as compatible, so the pack fits the same battery bay and works with the existing charging electronics in those models.
