A spare on charge
Swap it in, charge the other
The battery powers the electric lumbar and the five-minute OmniStretch cycle on the Omni Gen and the original Omni. It lifts out of the chair and charges like a power bank, so with a spare you can swap a fresh one in and charge the flat one at your desk.
LiberNovo rates a full charge at about 30 days of one OmniStretch cycle and five lumbar adjustments a day, roughly 41 stretch cycles, or up to a year of occasional lumbar adjustment. Taller or heavier users draw more from the motor.
Which battery?
Choose by chair, then colour
Graphite and Glacier are the Omni Gen battery, with a light-bar top and a loop handle. Midnight Black and Space Grey are the original Omni battery, with a smooth top. Both carry the same 2,200 mAh, 10.8 V rating.
LiberNovo says the original Omni battery also works in the Omni Gen, with a slightly different look. It does not fit the Omni Pro (3,000 mAh, which also runs the seat fan), and the Omni SE has no battery at all.

Frequently Asked Questions
Graphite or Glacier for an Omni Gen; Midnight Black or Space Grey for an original Omni. LiberNovo says the original Omni battery also works in the Omni Gen, but it looks slightly different. Colour changes only the look, not the electrics.
LiberNovo rates it at about 30 days of one OmniStretch cycle plus five lumbar adjustments a day, around 41 stretch cycles. With only occasional lumbar adjustment it can last up to a year. A 10-minute top-up gives about two stretch cycles.
Take it out of the chair and plug in a USB-C cable from any 5V/2A charger. A full charge takes about 3.5 hours. The light is orange while charging and green when full. A cable is not included.
The chair keeps working as a chair: sitting, reclining, height and armrests are all mechanical. Only the electric lumbar adjustment and OmniStretch stop until you charge or swap the battery. A red light on the control panel tells you it is low.
Yes. Every powered LiberNovo chair ships with one. This is a spare or a replacement.
