Review on 🔋 Creabest 4800mAh Ni-MH Replacement Battery for iRobot Roomba 400 Series - Long-lasting Power and Compatibility by Jennifer Johnson

It comes fully charged and works flawlessly with Roomba twice. After 32 days (2 days after the end of the return period), the battery is not charged at all. I contacted the seller to see what they would do and got no response. Maybe it was a bad unit, or maybe they're all bad. Are you willing to take the risk? I wouldn't do it after reading this review. I took a chance with a product that had no reviews and I lost. Learn from my mistake.
