Customer Reviews

Try this before ordering a new battery
Your Roomba may be experiencing an issue where the battery is deeply discharged and may need to charge longer than the standard 2.5 hours. (or 6 hours if you have a standard charger)

If you have fully charged your Battery (the Roomba Power light is solid green) and it charging time was short (less than 20 minutes) and its run time was short (less than 20 minutes) you will need to do the following.

Reset the Roomba charging system. Do this by removing the Battery and holding down the "power" button for at least 5 seconds. Then reinstall the Battery.

Plug the Charger into Roomba (avoid using the Home Base if you have one so as to ensure the Roomba's charging cycle is not interrupted.)

Charge the Battery until the Roomba Power light is solid green and keep the Roomba on the Charger for an additional 72 hours (3 days). Note: Do not interrupt this charging cycle.

In Max mode, run the Roomba for one complete cycle without a Home Base present, to deplete the battery. Keep track of the runtime and if it has improved, repeat steps 3 and 4 a few times. If your Roomba does not have Max mode, run several Clean cycles until Roomba stops and plays the "dead battery" song.

Old Roomba revived from the dead
I wasn't quite sure why my generation 2(?) Roomba would just shut down right after starting, but I suspected the rechargable battery. This battery works almost twice as good as the original one. 49.99< 279.99.... You know a brand new Roomba!

Extend the life of your Original Roomba
Though a different color, this is indeed the proper replacement battery for original Roombas. If you are lucky enough to have one of these classic machines around in good mechanical condition, do not fret and buy this battery now. You will be amazed and how your little guy springs back to life. Though a bit pricey, this is far less than you'd spend on a new machine. Unless you really need the features introduced on the new units, buy this intead.

My unit went from barely being able to complete one room - and slowly, at that - to doing at least five rooms, each at top speed.
