  • Made from high quality matched NiMH Sub C cells.
  • Designed for replacing iRobot ® Roomba ® 400 and 4000 series vacuum cleaner battery.
  • Longer run time than OEM battery pack.
  • Thermistor installed to prevent over charge.

This product is a generic replacement, not the original OEM battery. *iRobot®, Scooba®, Roomba® are trademarks of iRobot Corporation. This product is not subject to any warranty by iRobot.

Usage Note: After you installed the new battery, allow the 16-hours recondition cycle to take place. We recommend plugging the power supply directly to the robot instead of using the charging base. The condition light should give a fast orange flash during the recondition cycle.
