1.0 out of 5 stars Does not live up to expectation, June 13, 2011

First, this battery did not come with a label that shows the brand name and power rating, which questions the quality. It worked for about 1hr for the first time before roomba signaled for docking. After recharging overnight it worked for 30mins before roomba signaled for docking. Now the battery does not work for more than 20 minutes. The advertisement says it can work for up to 2hrs and I expect it to live up to 85% of the claim. It is even worse than the original battery that came with the roomba. I think the manufacturer needs to send me another one that will hold up to that claim.

This review is from: 14.4-Volt 3300 mAH NiMH Replacement Battery For iRobot Roomba Discovery 500 Series Robotic Vacuums (Electronics)

I decided to purchase this 3300 mAH battery and pay the extra four or five dollars. The delivery time was very fast. I ordered it Sunday afternoon and it arrived early afternoon on Wednesday. I put it in my Roomba and let it charge for maybe half an hour. Then I couldn't wait any longer and put it on its mission. I cannot recall ever seeing my iRobot Roomba 530 with this much vigor even when it was new. The old NiCad battery never did have much pep. The new NiMH battery is even pushing my dining room chairs a little before it backs off. My wastepaper basket is definitely in a new location. I do not recall seeing a specification label on the NiMH battery I received. I'll pull off the bottom backing place of the Roomba and check again. I would like to know it is at least labeled as 3300 mAH. I paid an extra $5 to get 3300 mAH versus 3000 mAH.

Update: I let it charge overnight and then turned it on to vacuum 4 large rooms. It ran with vigor for a full hour before returning to the docking station to recharge. I don't know if it was running low on power or just thougth it had finished the job. But when I opened the dirt trap, I was really surprised to see so much cust and debris. I've never seen that much dirt on one pass previously. In fact, it had as much dirt as five passes with the old NiCad battery. It is obvious from the noise it makes and how it zips around that this NiMH battery is far superior to the original NiCad battery.

When I checked the price today, Amazon has it back in stock, but at a significantly higher price. I was about to order another battery for my upstairs Roomba, but now I may have to consider the cheaper 3000 mAH NiMH battery listed elsewhere on Amazon.

For the price of this replacement compared to what you pay if you get it from iRobot directly, this is a no brainer.
I have been using this for the last 4 months and its held up quite well. I'm quite pleased with the performance.
