<b>[Product Information]</b><br>
<ul>
<li>5200mAh High Capacity Battery Replacement: Newly developed high 5200mAh capacity will power your iRobot Roomba for much longer. This capacity can run the Roomba for up to 5 hours. An extra 2 hours compared to the original battery that comes with the unit! Original NiMH battery is only 3000mAh & runs for only about 3 hours. Testing done on model Roomba 650 *Usage time may vary based on models and flooring surfaces.*</li>
<li>Package comes with bonus accessories! Including: 1 brush cleaning comb plus 4 side brushes (2 for Roomba 500 600 & 700 series and 2 for Roomba 800 & 900 Series).</li>
<li>Upgrade to the Newer Lithium-ion Type: Older NiMH & NiCd batteries have self discharge and memory effects that will require more maintenance, even when in storage. With lithium-ion batteries, only about 1% of power will be depleted per month when not in use vs NiMH’s 25% self discharge rate.</li>
<li>Lithium Battery That’s Safe To Use: Battery pack’s cells meet UL1642 & CE safety standards to ensure that your upgrade to lithium will be safe to use as a replacement for your Roomba unit.
