Title: Not iRobot as advertised/product photo - overpriced aftermarket knock-off
Review: IT IS NOT THE OEM iRobot BATTERY advertised! I purchased this specific battery because it was the least expensive OEM battery I found (Listed as iRobot plus iRobot battery photo). It is an aftermarket knock-off. Amazon sent a Chinese off brand "DucGreen". Similar aftermarket batteries can be purchased elsewhere for $10-$15 less. It provided 45 minutes operation with my 400 series Discovery after a full charge. I will return it. Check this one if you don't mind an inexpensive, aftermarket replicaCard Tenergy Replacement Battery (Grey Color) for iRobot Roomba 4905 400 series Vacuum CleanerAt least you will get what you paid for.
