How long does the battery last?
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 a new battery is likely to work for several years, ndd recommends that the battery be replaced every 1–2 years to ensure trouble-free performance.
