14.4-Volt 3300 mAH NiMH Replacement Battery For iRobot Roomba Discovery 500 Series Robotic Vacuums for sale
First, this battery failed to come with a label that shows the trade name and power rating, which questions the quality. It worked for around 1hr the very first time before roomba signaled for docking. After recharging overnight it worked for 30mins before roomba signaled for docking. Now the battery can not work for more than twenty minutes. The advertisement says it could possibly benefit as much as 2hrs and that i expect it to live nearly 85% in the claim. It's worse versus the original battery that included the roomba. I'm sure the producer needs to send me one more which will save claiming.
