Compatible Roomba models

This FYIOGXG lithium-ion battery replaces the original power pack in iRobot Roomba i3, i4, i7, i7+, i8, i8+, J7 and e6 series vacuums. It matches the 14.4 V voltage and 2600 mAh capacity of the factory cell. A fully decoded chip communicates with the robot exactly like the original battery. The pack is certified to ISO 9001, RoHS and CE standards.

Thermals and safety

The battery integrates overcharge, over-discharge, over-voltage and short-circuit protection circuits. These safeguards keep cell temperatures within safe limits during normal cleaning cycles and while docked. No active cooling is required; the vacuum’s own airflow passes over the pack. The protection logic helps maintain stable voltage delivery throughout the discharge curve.

Fit and installation

Physical dimensions are 74.20 x 51.00 x 50.20 mm and weight is 225.0 g, matching the OEM form factor for a direct drop-in fit. The connector aligns with the original socket; no soldering or adapter cables are needed. Many installation videos are available online for reference. The pack ships in shock-absorbing foam to prevent transit damage.

Questions about this item

How do I install the FYIOGXG 2600mAh 14.4V battery in my Roomba i7+ and what step is often missed?

Remove the side brush and bottom cover screws, swap the old pack for the new 74.20 x 51.00 x 50.20 mm unit, then press the connector firmly until it clicks — the step most people miss is fully seating that connector.

What maintenance will this 2600mAh lithium-ion pack need later?

Run two or three full charge and discharge cycles when new to reach peak capacity, then avoid storing the robot above 60 °C / 140 °F and never use a low-quality third-party charger.

What limit appears first during long cleaning runs with this 37.44 Wh battery?

The 2600 mAh capacity sets the runtime ceiling; once the pack is depleted the Roomba must return to its dock to recharge before continuing.
