Will This Battery Work in Your Roomba?
Dentsing lists the ABL-F 75Wh for the Roomba i7 and i7+, plus several other e, i and j series models. That list comes from the product listing, not from iRobot. Run this quick check before you buy.
iRobot warns that aftermarket batteries can trigger charging errors, and it lists Charging Errors 17 and 23 as signs of a battery that may not be authentic. A model on Dentsing’s list is not a guarantee that your robot will accept the pack. Customer reviews on the listing report both working and failed installs.

All ABL-F values above are advertised figures and were not independently measured. The product page URL still carries a 4460mAh reference, while the listing text says 5200mAh. At 14.4V, 5200mAh works out to about 75Wh and 4460mAh to about 64.2Wh. That gap is why the label on the battery you receive matters.

The difficulty score and effort split are an editorial estimate. The easy rating and five-minute time come from iFixit’s Roomba i7 battery guide. Charging time and any troubleshooting come on top.

Charging Error 1 means the robot cannot sense the battery. Remove it and reinstall it so it is fully seated. If the light ring is off, press CLEAN once or check the app for the charge status. If the robot shows Error 17 or 23, iRobot suggests a reboot: hold CLEAN for about 20 seconds with the robot off the dock.

Safety, Storage & Disposal
A swollen, cracked or hot lithium-ion battery is a fire risk. Do not charge it, and do not treat it as a routine swap. Contact the battery maker or a local hazardous-waste program for handling advice.
- Never pry into, puncture or squeeze the battery casing.
- Dentsing advises removing the battery for long periods of non-use and keeping it in a cool place.
- Keep old lithium-ion batteries out of household trash and recycling bins.
- Tape the terminals or bag each battery separately, then use a battery recycler or hazardous-waste collection point.
Roomba i7 Battery Replacement: FAQ
Does the Roomba i7 have a replaceable battery?
Yes. The battery sits under the bottom cover, near the center of the robot, and comes out after you release its retaining clip.
Is the Dentsing ABL-F an original iRobot battery?
No. It is a Dentsing-branded third-party replacement battery. It is not made or approved by iRobot.
Is the capacity 4460mAh or 5200mAh?
The current Amazon listing advertises 14.4V, 5200mAh and 75Wh, although the page URL still carries a 4460mAh reference. At 14.4V, 5200mAh equals about 75Wh and 4460mAh equals about 64.2Wh, which is why the label on the battery you receive is worth checking.
How long does the battery run?
Dentsing advertises at least 120 minutes per charge, but no test conditions or independent runtime test were found. Carpet, robot condition and real usable capacity all change the result.
What does Charging Error 1 mean?
iRobot says the robot cannot sense that a battery is installed. Remove the battery, reinstall it so it is fully seated, and contact iRobot Customer Care if the error stays.
What do Charging Errors 17 and 23 mean?
iRobot says these errors mean the battery may not be iRobot authentic, and that they can occur with aftermarket batteries. If the message persists, iRobot advises a reboot, which on an i series robot means holding the CLEAN button for about 20 seconds with the robot off the dock. A reboot does not guarantee that a third-party battery will be accepted.
Does a non-iRobot battery void my Roomba warranty?
iRobot’s battery compatibility page says parts not made by iRobot void the warranty, and its Limited Warranty excludes defects related to spare parts that iRobot does not provide or recommend. In the United States, FTC guidance says a warranty generally cannot be voided only because a third-party part was used, although damage caused by that part may be excluded. Check your warranty terms and local consumer law.
How should I dispose of the old battery?
Do not put it in household trash or recycling bins. Tape the terminals or bag each battery separately and take it to a battery recycler or hazardous-waste collection point.
