Replacement battery for Roomba 500-900 series

This 14.4V 3.3Ah NiMH pack replaces the original battery in iRobot Roomba 500, 600, 700, 800 and 900 series robots. It uses 12 Sub-C cells and fits the standard battery compartment without modification. The pack is built for owners who need a direct replacement when the factory cell no longer holds a charge. Buyers with newer iRobot models or non-Roomba vacuums cannot use this pack.

Thermals noise and power in normal use

NiMH chemistry runs cool during the vacuum’s cleaning cycle and does not require active cooling. The pack delivers up to 120 minutes of run time per charge and can be recharged up to 1000 cycles. Self-discharge is low enough that the robot is ready for scheduled cleans after sitting idle. No fan noise or extra heat is added beyond the vacuum’s own operation.

What the bundled items change

The package contains only the battery pack itself; no charger, tools or software are included. Installation is a simple swap using the Roomba’s existing latch and contacts. Because the chemistry and voltage match the original specification, the robot’s charging dock and firmware handle the pack without updates. Buyers needing a charger or diagnostic software must source those separately.
