Replacement Battery for Roomba i3 i4 i7 i8 J7

This 14.4 V lithium-ion pack delivers 3400 mAh capacity and fits Roomba i3, i4, i7, i7+, i8, i8+ and J7 models. It replaces original part numbers 4624864, ABL-D1 and ABL-D2 with a fully decoded chip that communicates with the robot. Owners of compatible iRobot vacuums can restore runtime without modifying the chassis.

Practical Limits of the 14.4 V Lithium-Ion Standard

The chemistry provides 48.96 Wh of energy and requires 2 or 3 full charge-discharge cycles before reaching peak capacity. A low-quality third-party charger will shorten service life, so the original docking station or an equivalent supply is recommended. Storage above 60 °C or 140 °F damages the cells, and the pack must never be disassembled, immersed in water or thrown into fire.

Build Quality and Connector Implications

The pack measures 74.20 x 51.00 x 50.20 mm and weighs 237.0 g, matching the original footprint for a direct drop-in fit. Over-charge, over-discharge, over-voltage and short-circuit protection circuits are integrated on the decoded board. Shock-absorbing foam in the retail box guards the cells during transit, and installation videos are widely available online for first-time fitment.

Questions about this item

Which Roomba models does the 3400mAh 14.4V battery fit?

The battery is listed for Roomba i3, i4, i7, i7+, i7158, i7550, i755020, i7558, i8, i8+, i8550, J7, e5, e5150, e515020, e5152, e5154, e5158, e515840, e6, e6198, e619820, 5150, 7150, 7550 and the 7150 series.

What does the 3400mAh 14.4V rating mean for daily cleaning runs?

At 48.96Wh the pack stores enough energy for typical whole-home cycles on supported Roomba models; actual run time depends on floor type, suction setting and battery age.

What connector standard does the battery use and what does it limit?

The pack uses the original Roomba ABL-D1, ABL-D2, ABL-D2B or ABL-F connector, so it only works with robots that accept those part numbers.
