    0 5/5 RCP14 - See all my reviews Verified Purchase(What's this?) This review is from: Tenergy Replacement Battery for iRobot 400 series Roomba (Electronics) This is my first review ever. I felt compelled to write it in order to help others looking for a battery for Roomba. I didn't want to spend $70 for a replacement. When I came across this one, I was somewhat skeptical. My robot had been out of commission for nearly three years and I considered throwing away. However, after promptly receiving the tenergy battery and charging it overnight, my Roomba started cleaning better and faster than ever. It ran around for approximately 1 hour and 20 minutes and it's extended the time which each subsequent charge. The price and the performance of this battery are just amazing! Thank you Amazon for providing this great product! 0 Help other customers find the most helpful reviews  Was this review helpful to you? , January 16, 2012

    Poor run time.

    I received this battery promptly and happily put it into my Roomba, which had a dead battery. It started right up and worked quite well.About 40 minutes later, my Roomba was dead again. The battery lasted only 40 minutes, when the product description claims it should run more than twice that. Either this is a dud battery or just a cheap ripoff.Please don't claim that a battery has 3.3 Ah of battery capacity when it clearly does not. There wasn't even a label on the battery.I can't recommend this product unless you're really strapped for cash.EDIT:After opening the battery, I can verify that the capacity is not the 3.3 Ah as advertised, but 2.6 Ah, more than 20% less capacity.Not only this but the company that makes the batteries is called Golden Dragon Battery, based in China.Shoddy product, false advertising, and reselling of other companies products makes me want to say with certainty that I would... 2/5 O.
