The 16-cell Inogen battery for the G5 and Rove 6 — Used

Inogen part BA-516 is the 16-cell battery Inogen lists as the double battery for the Inogen One G5 and as the extended battery for the Inogen Rove 6. This one is Used: a genuine Inogen battery, inspected and tested, sold with a warranty by American Oxygen for less than a new pack. Expect somewhat less runtime than a brand-new battery.

Fits the G5 and Rove 6

The same Inogen part, BA-516, is listed for both concentrators. The G4 and Rove 4 use their own batteries.

Tested & certified

Each Used pack is inspected and tested to confirm it charges and holds power before it ships.

Backed by us

Sold with a warranty by American Oxygen for peace of mind on a pre-owned pack.

Details

Which Inogen models does it fit?

✅ Inogen One G5 (see the G5)
✅ Inogen Rove 6 (new or Used)
❌ Inogen One G4 — Inogen lists only the BA-400, BA-404 and BA-408 batteries for it
❌ Inogen Rove 4 — same: BA-400, BA-404 or BA-408

Have an Inogen One G3? It takes a different battery: see the G3 battery.

Prefer it new? See the new Inogen BA-516 extended battery.

How long does it run?

Inogen One G5: up to 13 hours on flow setting 1, per Inogen’s G5 spec sheet and the current revision of the G5 manual.
Inogen Rove 6: up to 12 hours 45 minutes on flow setting 1 (±10%), per Inogen’s Rove 6 manual.

Those are Inogen’s figures for a new battery, and runtime is shorter at higher settings. A used battery may deliver less than a new one. Ask us and we can set expectations for your flow setting.

What's included

One Used Inogen 16-cell battery (genuine Inogen part BA-516). Chargers and power supplies are sold separately — for example, the Inogen BA-503 external battery charger.

Why Used

This is a genuine Inogen BA-516 battery that has been reconditioned, inspected, and tested. Cosmetic condition and remaining capacity vary from pack to pack; ask us about the unit you’d receive. Runtime is typically a bit lower than a brand-new pack — the trade-off for a much lower price. Every unit is backed by a warranty by American Oxygen (ask us for the current term). For context: Inogen designs these batteries for 500 full charge/discharge cycles, and a pre-owned pack has already used part of that life.

In short: The Inogen BA-516 is the 16-cell battery for the Inogen One G5 (where Inogen calls it the double battery) and the Inogen Rove 6 (the extended battery); Inogen doesn’t list it for the G4 or Rove 4. With a new battery, Inogen lists up to 13 hours on flow setting 1 in the G5 and up to 12 hours 45 minutes on setting 1 in the Rove 6; a used battery may deliver less. This Used unit is a genuine Inogen battery, inspected and tested before it ships and sold with a warranty by American Oxygen.

Frequently asked questions

Is this battery new or used?

It’s Used — a genuine Inogen BA-516 battery that has been reconditioned, inspected, and tested. It’s not new, but it’s confirmed to work and it’s backed by a warranty by American Oxygen. Prefer it new? See the new battery.

Will it fit my Rove 6?

Yes. Inogen’s Rove 6 manual lists the BA-516 as its extended, 16-cell battery, next to the standard 8-cell batteries (BA-500 and BA-508). It also fits the Inogen One G5, where Inogen calls it the double battery.

Will it fit my Inogen One G4 or Rove 4?

No. Inogen’s G4 and Rove 4 manuals list only the BA-400, BA-404 and BA-408 batteries. For those units, see the G4 / Rove 4 double battery.

How long does a used battery last?

Somewhat less than a brand-new pack, since used cells lose a little capacity over their life. For reference, with a new battery Inogen lists up to 13 hours on setting 1 in the G5 and up to 12 hours 45 minutes on setting 1 in the Rove 6. Ask us and we can set expectations for your flow setting.

How long does it take to charge?

Inside the concentrator, up to 4 hours in the Rove 6 and up to 6 hours in the G5, per Inogen’s current manuals. With the BA-503 external charger, about 9 hours from empty.

Can I take it on a plane?

As a spare, a lithium-ion battery can only travel in your carry-on bag, never in checked baggage, and each spare must be protected against short circuit (original packaging, taped terminals or its own bag). Whether a spare is allowed, and whether it needs your airline’s approval, depends on the watt-hour (Wh) rating printed on the battery’s label, so check the label and confirm with your airline before you fly. For flights, Inogen’s Rove 6 manual recommends bringing enough battery for at least 150% of your expected flight time, plus time on the ground, security, connections and delays, and notes that the AC power supply can’t be used to charge the battery on board.

How should I store it?

Inogen recommends storing batteries in a cool, dry place at 40–50% charge, charging to 100% and running down to empty at least once every 90 days, and keeping them dry (if a battery gets wet, stop using it). If you have more than one, label them and rotate.

What warranty comes with it?

It’s covered by a warranty from American Oxygen. Contact us for the current warranty term before you buy.
