Review on Hanaix 4800MAh Replacement Battery IRobot by Robin Williams

This battery has a capacity of 4800 mAh. Other batteries say they are 3500 mAh. So mine should have almost 28% more capacity. Not so. I only get 90 minutes of use from this battery. 3500mAh batteries provide 90 minutes of use time. For those looking for the best value for money, you can get batteries from 3500 to 3800 mAh. You save more money on a hit.
