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). The Best Cost/Performance Ratio The REAL Cost You Pay for Daily Usage - Our lithium battery: $96/800 charge cycles = about $0.12/cycle - OEM Ni-MH batteries: $49.99/200 cycles = $0.25/cycle - Aftermarket Ni-MH batteries: $42/200 cycles = $0.21/cycle (3800mA or 4000mA) Features: - The first lithium rechargeable battery for iRobot Roomba 500, 600, 700, 800 Series and Scooba 450, - 4400 mAh capacity can have 80-110 min running time, Compared to the original 3200 mAh battery 50-70 min running time (operating time, varies between models) - Fully compatible with the original charger - Patent battery balancing technology for expanded battery life; remains fully functional after 800 charge cycles - Built-in over-charge, over-discharge, over-voltage, over-current, and over-temperature protection - No memory effect, Low rate of self-discharge (1 percent per month) - One year warranty iRobot are registered trademarks of iRobot Corporation.
