Better performance, durability, and 4 times the battery life! Meets UL & CE safety standards!

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)
