Compatible replacement battery

This lithium-ion pack replaces the original power source in AEG Electrolux Osiris RX7, RX8 and RX9 robot vacuums. It matches the 7.2 V rating and 3400 mAh capacity specified for part numbers such as 900258195, 900277268 and OSBP72LI. The fully decoded chip communicates with the vacuum’s electronics exactly like the factory cell. Buyers who need a higher-capacity pack or a different voltage cannot use this unit.

Physical fit and installation

The battery measures 77.10 x 58.80 x 25.40 mm and weighs 121.0 g, matching the OEM footprint so no chassis modification is required. A standard connector plugs directly into the existing harness, and numerous online videos demonstrate the straightforward swap. Builders who lack access to the battery compartment or whose vacuum uses a proprietary latch design will find this pack unsuitable.

Thermals and power behaviour

The 24.48 Wh energy rating delivers typical run-times without exceeding the vacuum’s thermal envelope. Normal charging cycles operate well below the 60 °C / 140 °F storage limit noted in the safety data. No active cooling is needed; the pack relies on the vacuum’s existing airflow. Users who routinely run the robot in extremely hot environments should monitor pack temperature during charge.

Questions about this item

How long will the 3400mAh capacity last before the vacuum needs recharging during a full-house clean?

The 3400mAh lithium-ion pack stores 24.48Wh at 7.2V. Runtime depends on the vacuum's power draw and floor type; expect a gradual voltage drop under sustained high suction rather than a sudden cut-off.

Does the 121.0g battery get hot or noisy when the robot runs for hours on a single charge?

The battery itself is silent and has no moving parts. Under continuous load it will warm slightly; the vacuum's own motor and airflow generate the audible noise. Avoid charging above 60°C ambient.

My Osiris RX9 uses part number OSBP72LI — will this pack connect without an adapter?

Yes. This unit is built for OSBP72LI and S91-0400410-SU2, matching the original connector and the fully decoded chip. Confirm your model number against the listed RX7, RX8 and RX9 variants before fitting.
