Review on Powerextra 7.2V 2200mAh Replacement Battery for iRobot Braava 320/321 & Mint 4200/4205 by Trent Kraft

Revainrating 5 out of 5

Updated - Very easy to install in Mint and works great after 7 months!

Worked great with my Mint! It was very easy to install. I just opened the battery compartment, disconnected the old battery and put this in. The battery was the same size as my old one. My Mint sweeper now runs twice as long as it did with the old battery. Update: This battery is still performing strong. 7 months of continuous use and the battery life has remained the same. It charges quickly and still lasts twice as long as the old battery that came with it.

Pros
  • Beautiful
Cons
  • Almost never
