Ossur describes it for people with low to moderate activity levels and frames it around safety and mobility. The maker's page does not list the weight limit or battery life, so those figures are confirmed in the reply to your enquiry.

For transfemoral users with low to moderate activity who are comparing microprocessor knees and want one that does not rely on hydraulics. Suitability is assessed, and the knee fitted and programmed, by a prosthetist.
This kind of device is prescribed and fitted by a clinician. An enquiry starts that conversation. It is not a purchase.
