Easy replacement of dead battery, just remove soldered battery wires and solder on new battery ones. Completed in 10min."

The battery pack came in fast and it works great. It charges up in 2 to 3 hours. My original one needed 8+ hours to charge.

This thing is a great $$ saver, though you pay for it in the difficulty of removing the lid from the old battery. It can be done with patience, just be aware that it's not a 5 minute thing to install these.

As others have mentioned, the battery case is hermetically sealed. A couple of regular screwdrivers will get it open with a few minutes of careful prying. The replacement pack comes with short leads. It's probably easier to connect the old leads to the new ones and use the heat shrink tubing on the connections. I chose to desolder the old contacts and solder the new leads to the contacts. It's tight working quarters in there and in hindsight wished I had just spliced the wires together.

I give it 4 stars, not for the effort level, but for the lack of documentation.

I'm very pleased with the ease of replacing battery packs, the price and the performance. I highly recommend this method of updating Roomba battery packs.

It was a life saver to read all the previous purchasers and their stories. I was ready for the hassle of replacing non-user replaceable part. That readiness was sure needed as I wiggled a big knife through the glued up battery casing.

I am happy with the result. iRobot is an excellent product and they didn't use cheapest possible battery for their Roomba but this Tenergy batteries are one of the latest and it does hold the juice very well. Now I have my casing glue removed, I can forever keep my Roomba going. I love you iRobot! I hope you do more! My next lawn mower has to be from iRobot.

I, like some of the other reviewers, only got about 10 uses out of this battery before it quit holding a charge. By this I mean, it runs for 1 second and sings "come and find me"... which isn't as fun as usual because he will still be sitting at your feet. I used the roomba's service mode to run the wheels continuously to drain the battery down to zero. After a long day-long charge, it again rain for 1 second and stopped. No gain. Sad roomba.

The pain part is that it took forever to crack open my old APS battery as mine was very thoroughly sealed shut. I would recommend trying to open your battery before buying a kit like this to make sure you have one that is easy to open. Once open, the new battery kit does not fit quite right and required some force to get it in the old battery case. Then the new wires do not come with friction fittings or any other kind of connector.. just bare wires requiring soldering skills.. and a soldering iron.

Spend the extra $$ and get an irobot NiCD battery.. roomba just may not be compatible with the NiMH or I received a defective product. 2 stars if all you need is the triangular screwdriver and a blue and red doorstop.

this worked amazing for about 6 months of light use - it would run and run and run.
too bad that a few weeks ago, the run time went from 1.5 hour + to only about 10 minutes. I know NiMH batteries dont last forever, but with this light use it seems like i should have gotten at least a year's use from this

Originally, I was very happy with the replacement cells for the Roomba APS battery, but after about 6 months of cleaning 3x per week runtime has decreased dramatically. Now, my scheduler discovery won't run for more than 15 minutes regardless of attempts to discharge and recondition.

As others have noted, if you plan on keeping your Roomba running, either buy the iRobot OEM battery and have it last a year and a half (like mine) or bite the bullet and find Li-ion cells.

These batteries got used 5 times and then wouldn't hold a charge anymore. Now that iRobot has lowered their battery packs I'll be buying them from iRobot.
