Up to ~4.7 h

Details

What's included

One genuine Inogen One G3 8-cell standard battery (part BA-300). Recharges through your G3 with its AC or DC power supply; chargers are sold separately.

Why genuine matters

A genuine 8-cell pack delivers the G3's full rated runtime with the correct charge management and a secure fit. Generic batteries can under-perform, charge inconsistently, or fit loosely in the bay.

Frequently asked questions

Standard or extended — which do I need?

The standard 8-cell (this one) is lighter and runs up to about 4.7 hours on setting 1 — great for daily use. The extended 16-cell BA-316 roughly doubles that (up to about 10 hours) for long days and travel, with a bit more weight.

Which model does it fit?

The Inogen One G3 only. It won't fit the G4, G5, Rove 4, or Rove 6.

How long to recharge?

The standard battery recharges efficiently through the G3; recharge time varies with the flow setting and whether the device is running while it charges.

Is it genuine?

Yes, a genuine Inogen One G3 standard battery. It ships free in the USA.

Can I fly with it?

It's lithium-ion, so airline rules for spare batteries in carry-on apply. Check your airline's policy before traveling.
