Review on Hanaix 4800MAh Replacement Battery IRobot by Brittney Shallenberger

Had to replace original purchase as only charged twice then shut down. The second battery was the same, but now 30 days have passed. However, the description states a 365-day limited warranty. I wrote the company a letter and received no reply. I will contact Revain soon to try to contact the seller again. I would definitely not recommend.
