Aequitron Medical Puritan Bennett LP10 portable volume ventilator, new battery

Description

Aequitron Medical Puritan Bennett LP10 portable volume ventilator, used, new internal battery, starts working when turned on (a warning shows because tubes are not connected).
Available optional parts that I can include upon request (no extra cost): Electric cord for an additional external battery to extend uninterrupted work during power outages (needs a battery connector on the other end depending on the battery that you'll use), and spare air filters (when you change them, they are on the back of the ventilator).
Disclaimer: Ventilator has not been inspected by a certified technician recently, so no representations are made about its readiness, it is provided as-is.
