Replacement battery for iRobot Roomba models

This 5200mAh lithium-ion pack replaces the original battery in Roomba i3, i4, i7, i7+, i8, i8+, J7, e5 and e6 series vacuums. It matches the 14.4V specification and fits the same 139.16 x 51.38 x 50.50mm compartment. A fully decoded chip communicates with the robot exactly as the factory unit does.

Capacity and runtime headroom

The 74.88Wh rating delivers extended cleaning cycles on hard floors and low-pile carpet before the dock is needed. High-pile carpet, frequent edge cleaning or large multi-room layouts will drain the pack faster and may require a mid-run recharge. It is not suited for users who need continuous whole-house coverage without interruption.

Thermals, noise and power draw

The battery operates at the standard 14.4V and adds 425.0g to the robot's weight. No active cooling or fan is present, so the pack runs silently and contributes no audible noise. Normal charging current stays within the robot's built-in limits, and the casing is rated for storage up to 60°C.

Questions about this item

Will this 5200mAh 14.4V battery fit my Roomba e5154 and i7550 without any adapter?

The battery is listed as compatible with Roomba e5154 and Roomba i7550, plus many other e5, e6, i3, i4, i7, i8 and J7 models, so it replaces the original pack directly.

How can I confirm the new battery is working correctly after I install it?

After installation, run the Roomba through two or three full charge and discharge cycles; the built-in decoded chip communicates with the robot so the app shows normal capacity and runtime.

What comes in the box and do I need to buy a separate charger?

The package contains the 5200mAh 14.4V replacement battery weighing 425.0g with dimensions 139.16 x 51.38 x 50.50mm; the robot’s own dock charges it, so no extra charger is required.
