iRobot Roomba i7 Replacement Battery 14.4V 2600mAh ABL-D1

iRobot Roomba i7 / i7+ / e5 Series — 14.4V Li-ion Replacement Battery (ABL-D1)

This 14.4V, 2600mAh (37.44Wh) lithium-ion battery replaces the original ABL-D1 and compatible OEM cells in the iRobot Roomba i7, i7+, e5, and 7150 series robot vacuums. It fits the same battery bay and connector as the factory cell. Capacity figure is from the product specification — 2600mAh at 14.4V nominal.

• i7, i7+, and e5 platform compatibility: These models share the same 14.4V battery bay, physical connector, and BMS handshake protocol. A single cell covers the full range — no adapter or firmware workaround needed.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Roomba i7 dock. The BMS negotiated correctly with the charger, and the unit accepted the cell without error codes or charging interruptions.
• Dock charging practice for the Roomba i7: The i7 is designed to sit on its Home Base between runs — but leaving it docked continuously after it reaches full charge accelerates capacity fade. Charge to full, then remove the robot from the dock if it won't run again for several days.

Suction dropping before the battery indicator reaches low

The Roomba's motor controller pulls higher current on carpet than on hard floors. When the cell is aged or a filter is partially blocked, voltage sags under that load even though the indicator still shows adequate charge. The BMS reads pack voltage, not motor load — so it won't flag the drop. Clean or replace the filter first, then test again. If suction still drops early, check cell voltage under load with a multimeter — a healthy 14.4V cell should hold above 12.8V during active cleaning.

Roomba i7 motor cuts out mid-run and then restarts on its own

This is a BMS overcurrent trip, not a software fault. Sustained restricted airflow — usually a clogged filter or blocked intake — forces the motor to draw above the BMS current threshold, which shuts the cell down to protect it. The BMS resets once current demand drops, which is why the unit restarts a few seconds later. Remove and tap out the filter, clear any debris from the intake port, and run the unit again. If the cutout stops, the battery was reacting correctly to a real restriction, not failing.
