Review on Maximize Cleaning Efficiency with Powerextra High Capacity 7.2V 3000mAh Ni-MH iRobot Mint 5200 Vacuum Cleaner Replacement Battery for iRobot Braava 380, 380T, Mint 5200, 5200B, 5200C Floor Mopping Robots - Unleash the Full Potential of Your Cleaning Robot! by Kristen Campbell

I ordered this battery for our Braava 380t because it's the top rated replacement and costs a lot less than the OEM. The OEM battery lasted two years. This exchange lasted only a few days a year. Runs 20 minutes and just turns off. I'm not asking for help as the warranty expired a few days ago. I'll order another one to make sure it was an accident. Will hope. Updated 11/17/19. The seller who saw my review contacted me and offered to send me a replacement. I told them I had already ordered one and offered a refund. They obliged and reimbursed the cost of my replacement! This is excellent customer service. I have added a star and will update the new battery information again in the future.
