Premium Value - Safety and Reliability
  • Housing Design: Patent hard case to prevent damages from shock and vibrations
  • Battery protection:Built-in over-charge, over-discharge, over-voltage, over-current, and over-temperature protection circuit
  • CE certified and UN 38.3 approved
Why is there a need?
  • Longer Battery Life – Ultra High Capacity

  • Longer Storage Time
[ Roomba 980, 960, 890, 690, 614 and other lithium battery models ]
  • At least 33% more capacity and longer battery life than OEM lithium batteries’ 3,300mAh /2 ,100mAh / 1,800mAh

Please note the Roomba 900 series is designed with a limit to the operating time. It might not be possible to get over 2 hours of cleaning per charge. One benefit of increased capacity is prolonged charge cycles since a lower DoD (depth of discharge) is used per cycle. This means the battery will last longer than the OEM battery pack.

  • 46% longer operating time and 4X longer battery life than OEM Ni-MH battery’s 3,000mAh
