Review on Maximize Your IRobot'S Efficiency With SPARKOLE'S 5300MAh Extended Life Lithium Ion Battery For Roomba 500-800 Series by Dave Butler
Outstanding run time
I have been running my Roomba 770 CONTINUOUSLY for 7 hours after first charge in order to deep-cycle recharging first few times. I thought it would never stop. Re-charging now for second run. Whew.
Pros
- Home & Kitchen
Cons
- May take longer to charge than standard batteries
