- EasyOne® Air
The EasyOne Air spirometer uses a rechargeable lithium-ion battery. An empty battery can be fully charged in about 5 hours. A fully-charged battery can support the performance of approximately 100 spirometry test sessions. While the battery life is highly dependent on the intensity of use, ndd generally recommends that the battery be replaced every 3 years to ensure the best user experience.
