QA & Troubleshooting

Common questions regarding fitment, capacity, and installation.

How long does this 5200mAh battery last on a single charge? +

This massive 5200mAh ultra-high capacity battery provides up to 2.5 to 3 hours of continuous cleaning time, depending on your Roomba model and floor type (carpets use more power than hard floors). It significantly outperforms the original standard battery.

Is this battery compatible with all Roomba models? +

No. It is specifically designed ONLY for the older Roomba 500, 600, 700, 800, and 900 Series. It is NOT compatible with newer models that use a small square battery (such as the i Series, e Series, j Series, or s9). Please check your vacuum series before ordering.

Why should I choose this battery over the original factory one? +

Because it's a technology upgrade. Older original Roomba batteries used Ni-MH (Nickel-Metal Hydride) cells, which suffer from "memory effect" and degrade quickly. Our replacement uses premium Lithium-ion (Li-ion) cells. This means zero memory effect, a longer overall lifespan, and consistent power output from start to finish.

My old battery says Part Number 80501 / 11702 / 4419696. Will this fit? +

Yes, absolutely. This battery is molded to be a 100% exact fit replacement for original iRobot part numbers 80501, 11702, and 4419696. It will slot into your vacuum perfectly with zero error codes.

How do I install this replacement battery? +

Installation takes less than 3 minutes. First, unscrew and remove the side brush. Next, remove the 4 screws holding the bottom cover in place. Pull out the old battery by its green tabs, drop the new Coredy battery securely into the slot, and reattach the cover and side brush. You're ready to clean!
