Frequently asked questions

Does this fit the Oxlife Independence?

No. This pack is only for the O2 Concepts Oxlife Liberty2. The Independence uses a different battery (part 800-1002S), which we also carry.

Can I change it without powering down?

Yes — it's hot-swappable and tool-free. Keep a charged pack ready and swap it in without turning the unit off.

How long does it take to recharge?

About 1.5 to 2.5 hours per battery, in the device (AC/DC) or off-device with the single-bay charger. Time varies with temperature and battery age.

Is it a genuine (OEM) battery?

Yes, it's an OEM O2 Concepts pack. It ships free in the USA.

Can I fly with it?

It's lithium-ion, so airline rules for spare batteries in the cabin apply. Carry enough charged spares for your trip and check your airline's policy first.
