Very disappointed in this product. They describe this as an iRobot battery, and even put a picture of the iRobot battery in the product listing, however, and this should have been obvious from the price, this is NOT an iRobot battery! Now, I'm not an iRobot snob, and I would be perfectly happy with a generic replacement battery, IF IT WORKED! It holds juice, and it will power the Roomba, but upon docking with the home base, I get a one red blink error light (battery problem) and a fast red blink on the charge indicator light (never turns green after charging). I thought this could have been due to the Roomba forcing a deep recharge (16 hour cycle), but I left the Roomba on the home base for 24 hours, took it off, and the Roomba was still indicating it had no charge. I did a reset of the Roomba software (hold down the "spot" and "dock" buttons at the same time for 10 seconds), and only then did the indicator light turn green. As soon as I placed it back on the homebase however, the flashing red lights came back. It's not a problem with the Roomba either, I put the old iRobot battery back in, and the charge indicator light worked like it was supposed to. Until I get a REAL replacement, I'm stuck using my old, dying, iRobot battery... which is still better than the defective, generic battery that was sent by Battery Superstore.
Keep an eye out for an updated review. I have a message into Battery Superstore asking for a replacement of the defective battery they sent me. I will update this review with a review of their support, as well as any replacement they send out.
I sent a message to the seller, via the Amazon interface, telling them of the problem with the battery. They were quick to respond, and upon answering a few of their follow up questions, they were quick to process a replacement for the defective battery. I will update this review once I receive the new battery.
The battery they sent out to replace the defective battery, is defective as well. Same problems as the first one they sent out. I will be contacting the seller again to see if possibly there was a problem with the entire lot, or if I am just extremely unlucky in the batteries they have been sending me.
****** FINAL UPDATE******
Rather than keep sending me defective batteries, the seller has agreed to refund my money. They even sent a prepaid mailing label for me to return the defective batteries.
Overall, I'm disappointed that the product did not work, but I couldn't have been happier with the customer service. I ordered an authentic iRobot battery finally, and it works perfectly.
