How many spare POC batteries can I bring on a plane?

For batteries under 100 Wh (which covers most Inogen and OxyGo single and double batteries), the FAA sets no numerical limit—but you must be able to physically carry them. Use the 150% rule based on your total transit time to determine the exact number you need.

Can POC batteries go in checked luggage?

No. All spare lithium-ion batteries must be in your carry-on baggage. Only the battery currently installed in the device may be in checked luggage (inside the device). This rule is non-negotiable under FAA Advisory Circular AC 120-76E.

Roomba Battery Compatibility: Part Numbers by Model & Series

June 29, 2026 Cao Chuanping

The fastest way to order the right Roomba battery is to match the part number, not just the model name. The good news: across the whole Roomba range there are only a handful of battery families. Find your series in the charts below, confirm the part number on your own battery, and you're done.

How to use this chart: first find your model number (printed under the left wheel of the robot), then locate it in one of the two tables below. The part numbers listed are cross-reference codes — any of them on your old battery's label points to the same pack.

Roomba battery families at a glance

Every Roomba (and Braava mop) uses one of a few battery families, and they are not interchangeable across families:

Battery family	Series it covers	Voltage
R3 / 4376392	500 / 600 / 700 / 800 / 900	14.4V
ABL-D1 / D2 / F (e/i/j)	e / i / j series (incl. j9+ & Combo, with the right pack)	14.4V
ABL-B	s9 / s9+	14.4V
ABL-C	Braava jet mops	10.8V

The golden rule: a 600-series (R3) pack will not fit an i/j/s9 robot, and vice versa — match the family first. Note the Braava mops run at 10.8V, not 14.4V, so their battery is not interchangeable with any Roomba vacuum.

R3 platform — Roomba 500 / 600 / 700 / 800 / 900

These five generations share one battery platform, so packs are largely cross-compatible across them. The R3 cross-reference part numbers are 4376392, 1800LI, 4419696, 4INR19/65 and VB-063237 — if any of these is on your old battery, an R3 pack fits.

R3-platform Roomba models and their battery. Confirm the part number on your own battery.
Series	Example models	Battery (14.4V)
500	510, 530, 535, 550, 560, 570, 580, 595	4376392 pack `4376392` / `1800LI` / `4419696` 14.4V, 3300mAh/48Wh XLife extended-life option for 530–770
600	614, 615, 620, 630, 640, 650, 652, 660, 665, 670, 671, 675, 677, 680, 685, 690, 692, 694, 695
700	760, 761, 770, 775, 780, 790
800	801, 805, 850, 860, 866, 870, 871, 877, 880, 890, 891, 895, 896
900	960, 965, 966, 980, 981, 985

Older 500/700/800 units originally shipped with Ni-MH packs; you can drop a lithium-ion R3 pack into the same bay for longer runtime and a lower self-discharge rate — same 14.4V, same fit.

e / i / j series — ABL-D1, ABL-D2 & ABL-F

The newer e, i and j robots use a 14.4V lithium pack in the ABL family. Which one depends on your exact model — and unlike some guides will tell you, the right pack does cover the j9+ and Combo robots. Match by model:

e/i/j Roomba models and the matching battery we stock. Confirm the code on your own battery.
Your robot	Battery	Notes
i7 / i7+, j7 / j7+, i4 / i4+, e5, e6	ABL-D1 14.4V	The standard pack for the core i/j/e line
i3 / i4 / i7 / i8, e5 / e6 — extended runtime	ABL-F 4INR19/66-2, 4460mAh/64.2Wh	Higher-capacity option for the i/e series (not for Combo)
j7 / j8+ / j9+, i8 / i8+, i6, e5 / e6, Combo i5 / j5 / j9+	ABL-D2 / D2A 14.4V, 32Wh	Wide-coverage pack — this is the one that does fit j9+ and Combo models
j5+ / j6+ / j7–j9+, i8+, i6	ABL-F / D-series	Confirm your exact j-model; we'll match it

Good news if you have a j9+, Roomba Combo j7+/j9+: many generic guides say these "aren't covered," but the wide-coverage ABL-D2/D2A pack is made for exactly these models. If you're unsure, send us your model and we'll confirm.

s9 / s9+ — ABL-B

The flagship s9 and s9+ use their own pack:

Your robot	Battery	Notes
s9, s9+	ABL-B 4INR19/65-2, 14.4V, 48Wh/3300mAh	s9-specific — not interchangeable with i/j packs

Braava jet mops — ABL-C (10.8V)

If you have a Braava jet mop rather than a Roomba vacuum, note the different voltage:

Your robot	Battery	Notes
Braava jet m6 (and m6 6110 variants)	ABL-C 3INR19/65, 10.8V, 1775mAh/19Wh	10.8V — not interchangeable with any 14.4V Roomba pack

How to read your part number

Turn the robot over and find the model number on the label near the left wheel.
Remove the bottom cover (a few Phillips screws) and lift out the battery.
Read the code printed on the battery label — match it to 4376392 (500–900) or an ABL-D1/D2/F code (e/i/j), ABL-B (s9), or ABL-C (Braava).
Order the matching pack, equal or higher capacity at the same 14.4V.

Can you upgrade the capacity?

Yes — on both platforms you can fit a higher-mAh pack for longer cleaning runs, as long as the voltage stays 14.4V and the connector matches. A realistic capacity bump is a genuine upgrade. Be skeptical, though, of extreme "ultra-high mAh" listings in the same shell — many are inflated, and an honest-rated quality pack will outlast a bargain one with a fantasy number.

Frequently asked questions

Are all Roomba batteries the same / interchangeable?

No. Batteries are interchangeable only within a family that shares the same voltage, shape and connector. The 500–900 series swap among themselves (14.4V R3), and the e/i/j robots share the ABL packs — but a 600-series pack won't fit an i7, an s9 has its own ABL-B, and Braava mops run at 10.8V. Match the family first.

How do I know which battery my Roomba needs?

Find the model number on the label under the robot (near the left wheel), then look it up in the charts above. The single most reliable check is the part number on your old battery — match 4376392 (500–900), an ABL-D1/D2/F code (e/i/j), ABL-B (s9), or ABL-C (Braava).

Is the Roomba 600 battery the same as the 800 and 900?

Yes — the 500, 600, 700, 800 and 900 series share the 14.4V R3 platform, so a pack for one (e.g. 4376392) generally fits the others. You can interchange, for example, a 960 and a 675 battery. The i/j/s9 robots use different packs.

Can I use a higher-capacity (higher mAh) battery?

Yes, as long as the voltage stays the same (14.4V on Roomba vacuums) and the connector matches. A 1,800mAh and a 3,300mAh R3 pack are interchangeable — the higher one simply runs longer per charge. Never change the voltage to gain capacity; a mismatch can damage the mainboard.

Why won't my Roomba charge after I replaced the battery?

Usually it's installation, not a faulty battery. Re-seat the pack and check it's fully connected, make sure the contacts are clean, and "wake" a Li-ion pack by docking the robot for a few minutes. Many "dead on arrival" reports turn out to be a loose fit or a pull-tab left in place.

Does a third-party battery void my Roomba warranty?

iRobot recommends its own batteries, and a poor-quality pack that causes damage can put coverage for affected parts at risk. A quality replacement with Grade A cells, a proper protection circuit and certifications behaves like the original — which is what to look for if you go aftermarket.
