Roomba Battery Compatibility Guide

For each question, find out which pack is suitable for your robot, how to interpret the label, and what action to take when the names become confusing.

Start here: find your robot's model number

Each Roomba has a model number on a label attached to the bottom of the machine, close to the wheels. The number looks something like R960020, i715020 or j715020. This number acts as the robot's identity card and resolves all issues concerning compatibility.

The sticker located under the robot contains more answers than any forum thread; that's why I begin with it when asking about compatibility, since as soon as you have the model number, all the other information on this page can be treated as a lookup rather than a guess.

If there's no sticker, then open the app and look at the robot's settings page to see the model. If you're still having trouble, send us a photo of the robot and we'll tell you what it is before you place your order.

The full compatibility map

For each series there is one table; locate your robot on the left and the pack is what you need on the right, and in the 'part numbers' column you will find the numbers that are on the original battery's label.

There are two points worth making. The first is that each 'or' in the table represents an actual option, all of the ones listed being suitable. The second is that the complete model-by-model lists can be found on each product page in the collection, the fit lists on those pages being the full version of the story.

i Series & j Series, in detail

The i and j families are the ones in which the majority of people reside, and there are three groups which operate within them: the ABL-D1, the ABL-D2 and the ABL-F. The groups differ in their capacity but not in the robots they are aimed at, and their fit lists overlap. This is precisely the reason why the labels confuse people and why it is important to check the part number.

There's a straightforward way of looking at the three options. The D1 is the standard pack, the D2 is the upgraded version having greater capacity, and the ABL-F is the high-capacity choice, rated at up to 120 minutes on a charge. All three models cost the same, so the choice comes down to how long the battery lasts.

The full model-by-model listings, with the sub-model codes such as i7150 and j7550, can be found on the respective product pages. They are the detailed information and it's worthwhile looking them over before making a purchase.

s9 & s9+: its own pack, full stop

The S9 is the top-of-the-range suction robot and has nothing in common with the other models. One of the packs, the ABL-B, provides a voltage of 14.4V and a capacity of 74.88Wh. None of the models in the i series is suitable for it and none from the j series fits it either. The S9 is, in my opinion, the best example of how little there is in common between the different series.

That's the ABL-B pack for s9 and s9+.

e series: the budget workhorses

The e5 and e6 have the same battery platform as the i series, which is why they are cheap to maintain. They both use the ABL-D1 standard battery pack, and the high-capacity ABL-F pack will also fit.

500, 600, 700, 800 & 900 series: the long tail

The robots won't die, so their batteries will eventually run down. The 4376392 pack includes the entire range from the 500 series up to the 900 series. The XLife pack, which is the endurance model at 4400mAh, covers the 500 through 800 series as well as the Scooba 450.

Braava jet m6: the mop, not the vacuum

The Braava jet m6 is a robotic mop and it uses its own power pack, the ABL-C which is based on the 3INR 19/65 cells. It has nothing in common with the vacuums. The model is the one that sprays water.

The labels: ABL-D1 vs ABL-D2 vs ABL-F

The fact is that the three labels are used within the same robot family and their fit lists overlap, which is why they are confusing. The ABL-D1 is the standard pack, the ABL-D2 is the upgraded pack, and the ABL-F is the family name of the high-capacity packs based on the 4INR19/66-2 cells.

The names overlap, so the name by itself isn't enough to settle the matter; the part number on the label of your old battery is.

If you want to know the full details about the three labels, you can read the special article ABL-D1 vs ABL-D2 vs ABL-F, which explains each of them in plain English.

Part number decoding: what the label actually says

A Roomba battery has two types of numbers on its label and these numbers give different answers.

The 4INR refers to the cells contained within it; 4INR stands for four lithium cells connected in series, which is the reason why the voltage is 14.4V. The figures that follow indicate the type of cell, and it is this number that determines the specific pack. The 4INR19/66-2 is the high-capacity ABL-F pack, while the 4INR19/65-2 is the s9 pack.

The ABL- figures are the battery family codes used by iRobot, such as ABL-B, ABL-C, ABL-D1, ABL-D2, and ABL-F, the latter of which is part of the same family of names.

Then you have the long numeric part numbers, for example 4624864 and 4376392. Those are the OEM part numbers which appear in the manuals and on the original packaging.

To be honest, the OEM numbers vary from model year to model year, and the manuals can sometimes lag behind the robots. If the number on your label is not in this table, then the fit specifications listed on the product pages should be taken as definitive, and our support team will verify this before any items are shipped.

Not sure? Two checks that settle it

First, look at the label: almost all robots have two screws, one photograph, and the part number will answer the question. For the second check, send us the robot's model number and we'll compare the contents with your robot before you make the payment. All you need is the sticker under the robot.

If we had checked the label first, half of the wrong-battery returns that we observe would never have occurred. That's not meant as a lecture; it's the most inexpensive form of compatibility insurance you could get and it only takes one minute.

When to replace, and how to buy

When you have established which pack is suitable, two practical questions still arise: is it actually the time to replace it and how should you go about the purchase? Guides are available on both of these points.

Every pack in the collection ships charge-tested with a 1-year warranty and free shipping, and each one comes with the screwdriver you need for the swap. If you're still unsure between two packs, ask us before you order.
