Product Description

Better performance, durability, and 4 times the battery life! Lithium technology has been increasingly popular in the rechargeable battery market. Products such as laptops, smart-phones, and tablets all use lithium batteries. Currently, all iRobot Roomba batteries use Nickel-Metal Hydride (NiMH) technology with decreasing operating time after 6-12 months of use. The NiMh battery has memory effect and with high rate of self-discharge (over 25 percent a month).
