User Reviews about Generic iRobot Roomba Replacement Internal Battery Pack for Battery 4905. Fits Discovery - Sage - Red - and Dirt Dog Models

Bought these to fix a used Roomba. They charged, but then discharged instantly and took another 3 hours to recharge. Probably the Roomba and not the batteries. -- Batteries OK Repair Didn't Work

Easy replacement of dead battery, just remove soldered battery wires and solder on new battery ones. Completed in 10min." -- Cheap and easy replacement

The battery pack came in fast and it works great. It charges up in 2 to 3 hours. My original one needed 8+ hours to charge. -- Works as expected & charges up fast

This thing is a great $$ saver, though you pay for it in the difficulty of removing the lid from the old battery. It can be done with patience, just be aware that it's not a 5 minute thing to install these. -- Cheap alternative
