Replacement Battery for Electrolux Robotic Vacuums

This 7.2 V lithium-ion pack replaces the original OSBP72LI cell in Electrolux Osiris, RX7, RX8 and RX9 series robotic vacuums. It delivers 2000 mAh capacity and 14.40 Wh energy rating in a 77.10 x 58.80 x 25.52 mm form factor. The pack weighs 120.0 g and uses a fully decoded chip that communicates with the vacuum’s power management exactly like the factory unit. It is a direct drop-in replacement for part numbers 900258195, 900277487 and the full list of compatible models.

Fully Decoded Chip and Installation Support

The integrated chip is fully decoded so the vacuum recognises the battery without error codes or reduced functionality. No additional software or firmware update is required; the pack works immediately after fitting. The supplier notes that many installation videos are available online, making the swap straightforward for most users. The battery carries ISO9001, RoHS and CE certifications, confirming compliance with safety and environmental standards.

Suitable for Owners of Listed Electrolux Models.

This pack suits owners of the specific Electrolux robotic vacuums named in the compatibility list who need a new power source. It will not fit vacuums from other manufacturers or Electrolux models outside the listed part numbers. Buyers who cannot confirm their original battery part number against the list should look elsewhere.

Questions about this item

How many charge cycles before the 2000mAh 7.2V lithium-ion pack needs replacing?

The manufacturer highlights a 12-month warranty on the OSBP72LI, suggesting expected service life under normal use; actual cycle count varies with depth of discharge and charging habits.

What limits runtime first during a long cleaning session — capacity or voltage sag?

The 14.40 Wh rating sets the total energy available, so capacity is the primary limit; voltage sag under heavy load may cut power sooner on high-pile carpet.

Does the pack run hot or draw extra power when the vacuum runs continuously?

Lithium-ion chemistry stays cool at typical vacuum currents; the 120.0 g pack has no active cooling, so extended runs rely on the device’s own thermal management.
