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.

Frequently Asked Questions

Q: Which replacement battery fits my Roomba model?

A: Roomba i7, i3, i4, i8, J5, J7, J8, J9 and e5, e6 use ABL-F (4INR19/66-2). Roomba S9 and S9+ use ABL-B (4INR19/65-2). Roomba 600, 700, 800, 900 series use battery model 4376392. Check your Roomba's battery compartment label or original battery part number to confirm.

Q: What is the difference between ABL-D1 and ABL-F Roomba batteries?

A: ABL-D1 and ABL-F are very similar but have slight differences in capacity and compatibility. ABL-F (4INR19/66-2) is 4460mAh/64.2Wh and fits i Series and J Series models. ABL-D1 is an earlier variant for i7/j7/i4/e5/e6. Always match the part number printed on your original battery.

Q: How do I know if my Roomba needs a new battery?

A: Signs your Roomba battery needs replacement: runtime drops below half of what it used to be, the robot stops mid-cleaning and returns to base before finishing, the battery drains within minutes of starting, or the Roomba shows a battery error. Most Roomba batteries last 2-3 years with regular use.

Q: Can I replace the Roomba battery myself?

A: Yes. Replacing a Roomba battery takes 5-10 minutes with a standard screwdriver. Turn the robot over, remove the bottom cover screws, unplug the old battery, plug in the new one, and screw the cover back on. No soldering or special tools needed.

Q: How long does a replacement Roomba battery last?

A: A quality replacement Roomba battery provides up to 120 minutes of runtime per charge and lasts 500+ charge cycles (about 2-3 years with regular use). Higher capacity batteries like the ABL-F 4460mAh give longer cleaning sessions than standard capacity models.
